Let's Photograph the Rosette Nebula!

Processing Guide (Updated): bit.ly/astro-processing
In this video, I take you along as I photograph the beautiful Rosette Nebula in the constellation Monoceros. This winter has been COLD and CLOUDY, and getting outside for a night of deep-sky astrophotography has been tough!

A quick fix for keeping the warm air in the garage would be to hang a few thick drapes or rugs right next to the garage door. Open the garage door so the drapes covers the entire entrance and have a slit somewhere in them so you can push your way through with the gear.

[@michaelklemm-abraham7298]

Just wanted to write the same thing. Some thick fabric from ceiling to floor arround the garage door on the inside to limit the issue. You were faster than me.

[@nils-kopal]

I had 100% the same thought 🙂

[@danlangston4074]

I worked in a studio in NY that had the same garage door problem and we used a PVC strip curtain door to keep the cold air out of the office area. It’s basically a giant thick shower curtain but it is cut into like 6 inch strips so you can walk though it. Worked pretty well.

[@carterbeltz846]

You inspired me to get a telescope recently, and I just got my first picture of the orion nebula last night! I was so pumped to see it

[@alexandrustan5450]

Which telescope and mount did you used?

[@zabridges]

Check out insulated garage door screens with magnetic flaps. Looks like it would be a great solution for your heating issue. Thanks for making your videos! I have been watching since 2016.

[@TL1000S97]

It has been -35C here where I live (Norway), and I have been "shooting" in -25C at least at two occasions. I am impressed that the gear works (well, the ZWO Autofocuser is not happy below -20C). Yesterday it went from -22C to +4C! And rain instead of snow blizzards. It feels almost warm going out this night to shoot some more. 😂 The weather is not as it used to be when I was a boy (a long time ago). Hope we all can get some decent conditions/clear skies from now on. Always inspiring to see your content Trevor! 😍

[@AstroBackyard]

Thank you, and clear skies!

[@krystofmacek7996]

Here in central europe was only like -13°C at night. I tried to cool my camera to -40°C and cooler was only running like on 50% power, not sure if it made any difference but I tried 😂 When examining dark frames from -10 and -40 i could definitely see less hot pixels. Biggest issue was (like always) Asiair wifi connection, i looked like freezing weather made it worse 😂

[@netanmaldoran4816]

This is why I'm glad I'm in Arizona. Always clear and relatively warm :O

[@albertsmith5581]

El Nino is killing us this winter in Florida. This is our prime time observation season and since mid-november I bet we have had no more than 5 acceptable nights for viewing and photography. Rain and clouds have taken over our normal clear dry winter nights.

[@X_Excelsior]

Not much better here in Germany

[@Reddragon-lf3uq]

5 acceptable nights, sounds like a treat to me. I live in Estonia so every year we get a total of up to 40-50 acceptable nights for astrophotography.

[@SpaceMan_Dan27]

Absolutely cursed. I live East of Tampa. This has been the worst winter that I can remember in recent years

[@Messier269]

​@@X_Excelsiortrue it's horrible

[@AstroBackyard]

Brutal. I feel your pain!

[@perry3928]

Hi Trevor. Nice to see you back. What a great technique mixing different data from different scopes. Brilliant. Well done.

[@icyxxxxx]

I was searching for this nebula on KZbin and I remember ur channel and I searched it and saw this video 😂 amazing!

[@astrojudebob]

I'm across the lake from you, Trevor, and haven't had a clear night in two months. I feel like the next clear night won't be til galaxy season, lol.

[@mistafrags6113]

You work is amazing, your channel is my number 1 stop for any tutorial and just excellent shots of deep sky. LOVE IT !

[@michaelw6173]

Love the dogs squeaky. My dog gets them and straight away surgically removes the squeaker. But I got distracted. Great work. That part of the night sky has so many objects to image you could spend months enjoying it.

[@lampyman101]

I feel your pain on the weather this year. It's been an almost complete washout for me since like last spring with very few reliably clear skies. All too many times I've set up only for clouds to rush in after a few mins of capturing. Here's hoping for a better year this time around.

[@mohammadal-debsi9976]

RESPECT!!! For these super efforts in this cold..... and I thought carrying up the rig UPSTAIRS and downstairs was a difficult task.!!

[@hartcityparanormal115]

Absolutely stunning!!

[@HeavenlyBackyardAstronomy]

Nicely Done, Trevor. You are absolutely correct about Russell Crowman's Star Exterminator, Noise and Blur Exterminator ... They have a nominal price tag to them but are so well worth it.

[@jameschase9002]

Fantastic (as usual) Trevor. Thanks for the update on RGB stars!

[@SkyShedPODTeam]

Love it Trevor! Great stuff! CS!

[@TTV-Optic]

Hey bro I havnt watched in a while but now its coming back into better weather I thought I would hop by nice to see your still at it your the reason I own a telescope

[@robinhoward6447]

You are setting the bar Trevor! Wonderful images of the Rosette. Clear skies and keep giving us the targets to aim for. Clear skies from the UK!

[@AstroBackyard]

Thank you!

[@GFTJITMNTSBTKAT]

Fantastic image Trevor! Thanks for sharing the suggestion on the RGB stars. I just finished my first SHO image of Rosette, so I may go back and try the RGB stars. Love your channel!

[@johnpaterson4163]

absolutely stunning mate 👍🏻

[@liamross2636]

Fantastic image Trevor, here in australia, we’re suffering in the opposite climate! Trying to get a capture in 80% humidity at 30°C + is definitely a challenge. Looking forward to Milky Way season, both for all those targets, and the cooler weather!

[@adriangravelle1520]

That was totally Awesome!

[@muddyexport5639]

Excellent info and results!

[@stuartpinkney2340]

Awesome absolutely awesome

[@mwales2112]

Beautiful image Trevor... Thanks

[@OldCurmudgeon3DP]

The photo resolution is amazing. I liked the Blackmill track too.

[@donadams.6679]

Great video Trevor. Thanks!

[@EricTheCat]

Great result! From Minnesota I know what you mean about the cold weather. This season I got some glove/mittens where the gloves have open fingers and you can close the mitten over the fingers and also got thin "smart phone gloves" that fit inside those so if I need the dexterity or touch screen usage I can open those without fully exposing my fingers. Also plenty of hand warmers!

[@carlosespada6202]

excellent explanation and result! 👏👏

[@manufacturedfear]

In southern Spain we have sun during the day, clouds during the night 🥲

[@jwdeepsky]

So helpful combining those rgb stars. I'm gonna give it a go!

[@astronomybob]

Beautiful image Trevor!

[@Saturn-zi8rl]

You are the best Astrophotographer in the world ❤️❤️❤️❤️

[@gregorymckenna6609]

Re cold rushing in via garage door. You might try installing thick clear plastic strips (on the outside so they don’t interfere with the door or install them inside on a movable rack). This will block the cold. Same technology used in some walk-in freezers.

[@Tp_astro]

Awesome!❤

[@michelestorci7076]

Hi Trevor, thank you for your excellent work which has inspired me to go back to my telescopes after many years. Just wanted to rectify you on something you said: red stars are cooler than blue stars, it’s the opposite of the tap water. This is clearly discernible in the HR diagram. Apart for my OCD keep up the good work! Best, from Italy.

[@jaytroxel3495]

Really enjoying your videos.. subscribed! Thanks!

[@astrocarone9671]

Man I miss astro. The sky has been terrible. I can't wait to get back into it. Awesome shot.

[@crawfprof]

Great results and cool video as usual! Amazing that you've been able to get out and image. No such luck for me near Rock Point, but I've been out of the country, I see you have yet to set up your POD. I finally got mine off the deck and assembled (on the grass) just to have the additional wind break.

[@tiggandsoot]

Curtains are a good idea but they also make the hanging plastic louver type curtain . You could build a short wall inside so you end up with an Airlock kind of room

[@seventhsun1]

Thank you for the video!

[@thos759]

Wow …Wow … WOW !!!

[@nickkowal6537]

@astrobackyard For the heating issue get some curtains up around a small docking area by the garage door. Maybe something like room dividers or bodyshop curtains. Even just thick domestic ones. Ceiling mounted and running to the floor.

[@IcedReaver]

Nice video and final image! This winter, I've also been shooting the rosette in narrowband, but I've been doing a 2 panel mosaic to get the same field of view as you. I'm just missing the last bit of OIII data, but this weather has just been awful, no imaging for a month! PS if you're looking for advice on videos to do during cloudy weather, please make one on creating such a good horizon image in stellarium. Mine is kinda warped and I can't eliminate the background sky through a lot of the trees. Thanks!

[@skinfology]

As a complete newbie I don’t understand all this processing stuff but still hooked with your videos. Am I mad lol. By the way keep it up Trevor

[@canofanger]

All you need is a clear plastic sliding curtain to isolate that area when you open the door (like the spray booth type. That will keep the heat in the room.

[@romaindechamps457]

Nice video Trevor! I too own an EQ6R alongside a 130PDS, so a little less heavier than you rig. It sleeps outside under a shell with a protection bag on it and I carry it for few meters each time I go out, having the rig set. Makes it super easy to start a session an increase a lot my imaging time. One thing I noticed is that you had the clutches engaged when you move it and I was told that it could damage the rig (putting pressure and weight when balancing it around). To avoid this I just disengage the clutches - the scope is balanced anyway so it does not move much and this way I am sure it doesn't damage anything. I trust you've done this back & forth much more than I did but it might worth a try :)

[@aTillasSister]

Hi! Thanks for all the tuition and encouragement over the years. Here's an ASIAIR tip for continuing previous sessions. Keep a sub of each target stored on the ASAIR. From Preview, Image Management, load a sub and goto. It will goto the target and report any wrong rotation and how many degrees CW or CCW to align with the old sub. With a manual rotator on the OTA, you can rotate and refresh as necessary to get back into alignment for another session on the same target. I also mount the mobile device on a tripod for polar alignment.

[@mathewdespres]

Awesome! I know your coming to my town in a few months and I can’t wait to meet

[@3DAstroTC]

Still one of my favorite targets! The S/N of each channel 👌

[@geldingmakr]

Great video; nice work 🔭🤩👏

[@nigelray12]

You could make a platform for the scope to sit on that can be wheeled in and out of the garage. Make it so all your tripod scopes can be put onto the platform. Maybe to stop the cold air coming in is to have an inner and outer door inside the garage so you can place the scope in between the doors. When one is closed the other can be opened and no cold air allowed in.

[@nickwaslen698]

Hey Trevor and Ashley! Do you guys still enjoy birding and bird photography? I still go back to your bird nerds channel and watch some videos every once in awhile.

[@PineBloxx]

Awesome

[@stefanschneider3681]

Breathtaking 🤩! Was definitely worth freezing a bit 😉…

[@chridignan9178]

Beautiful image. Thanks for your video - very handy! We just have wind (99mph) and rain storms here in the UK - not great for guiding! Take care all. Chris

[@Jcorban08]

Super interesting video, as always! Love your final image too! I like this formula in pixelmath for adding stars back in ~((~starless)*(~stars)) It makes me feel clever whenever I use it 😂

[@masterxyr]

the extra mile really shows off here. spectacular image and subject. congratulations on your work I surprised myself by wondering which of the possible light spectrum combinations I preferred, since either one of the 3 always seems to cover the other. Had never thought about that and have yet to reach a conclusion too lol

[@huffbanger]

Excellent content, production and editing! Looks like you're getting good results with the ASIAIR. I just purchased one in attempts to streamline my process. NINA has been great, but I want stupid simple with less variables.

[@strykker666]

Absolutely amazing, as always, Trevor!! I would love to get those colors on Rosette. I'm actually shooting that target currently. But I'm using a 533MC Pro with a RedCat 51, and a L-eXtreme filter. Bortle 7 area. For some reason, my SWSA GTi won't meridian flip, and it's driving me nuts!

[@tomhoskins4913]

Outstanding work Trevor, I use linear dodge in the blending mode. I am still learning Pixinsight but always fall back to PS to finalize an image.

[@guyjordan8201]

Just a thought with your cold air problem with the rear garage door, would you consider putting on an airlock? A 2 m deep screen enclosure extension at that rear garage door, with plastic barrier during the winter, would drastically reduce the volume of air exchange in your garage. Love your videos

[@ronanhunt88]

Loop grippers are like the most key tool in astro!

[@briankotak403]

Great video Trevor! I’ve been waiting for this one. Sometimes my stars when using the L-extreme filter on my 2600MC Pro look horrible. Not always. Maybe scope-dependent. Anyway, I have been thinking about RGB stars for my narrowband images. Looks quite simple. Thanks! Dr B from Manitoba, Canada 🇨🇦 Hi Ash and Rudy!

[@stevepecket2535]

Hi All. UK weather is always crud but I was whining at -7C the other night...-25C is never stepping outside!!!!

[@ghost70]

Think you need a tuff truck wheeled mount there Trevor. Also why not run a cheap diesel heater like Chrome from Vancity vanlife does? Leave the door open a crack then puts an aluminium strip across the bottom with the exhaust and air filter on the outside . You will be toastie warm then .

[@AstroQuest1]

Brilliant image Trevor! Congrats. I had to do a double take of you using PixInsight haha😊. It is worth it though especially all of the add-ons from Russell Cromin and Bill Blanshan - also GraXpert is awesome. You can do all that in PS but it would take forever. I still do a lot of Photoshop stuff like you though. I have matched up diffrent FOV images where I ended up using the RGB stars for most of the image but used the NB stars for the part that was not covered by the RGB stars - although it was not as big as an area as as you had. Cheers Kurt

[@milwman1958]

Oil filter wrench is what it was! Scott

[@whyamibeingpesteredtogetahandl]

aka a strap wrench.

[@GediAstro]

Dude, you should come to my skies in Stockholm. I struggle with clouds for 3-4 months in a row and -20C. Also, I'm at Bortle 9. Still loving it :)

[@cjmenagh882]

Scope buggy and a side entry door for the garage sure would be nice.

[@jameswoods1939]

I'm betting the box has the Askar 185 inside :) I didn't get a good look at it, though. Great video, as always, Trevor.

[@AndreaGirones]

Strap wrenches are the best!

[@Jfoy42]

That's incredible!!! I've gathered some data on the rosette nebula, but I am gonna need to get better with processing the stacked image in PS. This does make me want to invest in a telescope rather than use my Canon DSLR. The 75-300mm kit lens doesn't tickle my fancy anymore. 😅

[@BobJohnsonSince1970]

Trevor, you need some JMI Wheeley bars to speed up your mad-dash in and out!

[@davidforcier4]

Missed opportunity to include "The Martian" SAS explosion killing all the crops while opening the garage door 😁 Great image!

[@wooddogg8]

🤣🤣😂😂👍

[@RobofGabriola]

Canada. Winter. Astrophography. I feel your pain. In fact, here on Gabriola Island, BC, in brotherly solidarity with your plight, my Seestar S50 is outside imaging M31 and I'm on the couch sipping scotch. Sure is cold out tonight...+5C. Location is everything. (Couldn't resist.)

[@gleadr6869]

Very nice Image! The center at the end looks like a hooded person with their arms crossed.

[@daniels_astrophoto]

Evening Trevor and Ashley 😊

[@joellc88]

It’s been like 6+ weeks of clouds and rain on the east coast of Australia. I’m starting to get a twitch

[@garyschmelz6728]

My only clear nights are in the middle of a work week and even then it is one night every three weeks or so. The tool is called a strap wrench.

[@OGParzoval]

Trevor I think I see or dont see the problem. That sky pod isn’t deployed :) Though seriously gloves with pockets on the back side of the hand and some hand warmers and your hands will feel pretty warm as long as they’re not being blown away by the wind. I’ve had the same issues, clear too windy, cold, and clouds, and usually being on the dry side of the Rockies at 7k feet we get these beautiful dry calm nights where the sky is clear. There’s also those nights it starts cloudy I dont pull the satellite imagery, go watch a movie or play a game and come out and it’s stupid late and the sky is clear and I’m just too tired lol. I see my own sky pod in the future. I’m a big computer nerd so automating it all is on my list.

[@fromupthere.2209]

Same here in Australia but because we have had cloud the whole month and still its cloudy.. :(

[@Katieyhughes]

Evening Ash & Trevor ☺️

[@benjaminmarks9440]

Be curious to see how the stars that result from a Spectrographic color calibration (with the emphasis on star correction) on the narrow band image would compare to the RGB stars? You could potentially get nice tight color corrected NB star profiles. Work flow would involve removing the SPCC color corrected stars (the nebula will probably turn green), playing with the nebula colours etc. then adding those SPCC corrected stars back in perhaps using the ~((~Image)*(~Image_stars)) formula in pixel math. The Image in this formula is the starless image that you’ve tweaked etc. and the Image_stars are the extracted SPCC corrected stars.

[@allenbaylus3378]

when you go to a food store - they have these long clear vertical blinds by the freezer to keep the cold air in and the warm air out. I am unsure what the name is but it may be worth looking into for a winter solution.

[@hamsterking5086]

I would love to see you capture IC 418 some time

[@chamallowgrille2493]

Due to your télescope, I think you can bought or create a simple wood plank with little wheels for get out all the equipment quickly

[@JoseLausuch]

My cooler is working hard to reach -20°C and yours just 3%... Omg, I just hope you can control everything from inside the house 😀

[@afd33]

Great video as always. My bedroom the heater doesn't work particularly well, and I've been amazed at how well a Dyson fan that has a heating feature works considering it's only a couple hundred dollars. It's loud enough you wouldn't be able to record with it on, but it could help warm things back up after the door was open.

[@Astronomyplace]

I got my new telescope at the beginning of this month and the weather is perfectly timed to be bad when I got it

[@Astronomyplace]

I wouldn’t really recommend the one I got I am sending it back and getting a 6 inch dobsonian, but it was a Orion observer 114mm 500mm aperture EQ

[@rockmusicvideoreviewer896]

Why not use your Radian Raptor telescope? I don't even see it anywhere? Why ? lol. 1:34

[@cierraarmijo]

I'm gunna guess the Celestron Origin is in that package :P

[@michaelt.9372]

I live in a Bortle Level 2 area and I want to get into astrophotography so badly.

[@bofblog]

Nice image with the conditions, would the garage door benefit from fitting hanging heavy plastic sheet pieces door drapes for holding the heat in during winter and easy to move during Summer

[@balmung1992]

Convert the layer you’ll be making camera raw adjustments too into a smart layer. This lets you go back in and tweak settings as the smart layer saves the edits as opposed to using the history tool.

[@davidsimard1522]

Welcome in my world east coast of New Brunswick we get all weather conversions on top of us

[@timbotron4000]

The big box in the garage is the Askar 185??

[@allenbaylus3378]

Askar 140 or 185 - that was my guess as well... It's hard to guess scale since it is packed in a shipping container with padding and lying down on its side - so I lose the length.

[@TSteeyo]

Tip here: Using the bottom of a computer mousepad can help you get really good grip to unscrew stuck filters, extenders, etc, trust me!
