Am I just listen to the vampire telling me how to process astro photos? 🤣 Great idea Nico!

[@NebulaPhotos]

🧛‍♂️

[@ChrisTurchin]

I was 15 minutes into the video (listening while cooking) until I noticed this too 😂😂😂

[@roderickwho1983]

Jesus Christ, its Count Chocula !!!! Thanks for another great video Nico.

[@SarahMathsAstro]

Excellent tutorial, Nico! And the end result is spectacular.

[@NebulaPhotos]

Thanks Sarah!

[@jeffreysokal7264]

Nice job with the processing, gave me some help. Great job with the makeup! Gave me a good chuckle.

[@michaellorentzen1672]

Thank you so much for an editing video. These are crucial to the nascent astrophotographer. I always learn something new. Every single one of my completed projects has benefitted from an editing video

[@buzzbuoy]

Intro cracked me up! Happy Halloween to you too lol

[@younesel]

Thank you for this knowledge. I find this more of an intro for the people who want to start. There is no in depth explanation, but that is good. It walks you through the steps to take to achieve this result. For me a great video, left with a need for more.

[@HelenasAstrophotography]

This is awesome Nico!! Loveee the costume

[@zxwolf4641]

This is absolutely brilliant - thank you so much Nico! You have quite honestly been one of the biggest reasons for me getting into astrophotography for this reason exactly!

[@NebulaPhotos]

Glad you enjoyed it! Thanks!

[@jackthecat6225]

This is so timely. I had just downloaded Siril and you posted this video the very next day. Thank you so much!

[@azrayastrophotography2260]

Hi Nico, Great information on LRGB processing with Gimp. I use both Siril and Gimp to process my images. I did not know how to add the Lum layer to my images. Thanks again.

[@astroadventures3559]

Awesome demonstration brother. I appreciate the hard work you put in these videos and the fantastic information you're sharing. I'm definitely going to be giving this a try when I get home tonight.

[@astroadventures3559]

Man I love this video idea so far lol awesome way to celebrate one of my favorite holidays from one of my all time favorite KZbinrs. Thanks for this Nico🤘

Mine too! Happy Halloween 🎃!

best video ever :)) tnx

[@DrJ_MKE]

Great video Nico - I always learn some great nuggets from you - thanks for doing these as I use Siril & GIMP exclusively, so these are very helpful. I just wish I had seen this video 48 hours ago as I unknowingly updated to Ventura and I can confirm that Siril does not operate properly with Ventura - UGH!!!! Not exactly sure how to revert from 13.0 back to 12.6 as I don't have Time Machine established or back-ups, etc. and don't want to lose anything if try to re-install 12.6 from the App Store (?). I'm going to reach out to Siril and see if they have a timeline in mind for a fix as I'm dead in the water right now.

[@NebulaPhotos]

Oh no! So sorry to hear that Eric, what a headache. From what I heard on twitter, it is a big problem, so I'm not sure they have a timeline yet.

[@DrJ_MKE]

@@NebulaPhotos You may have already seen it, but Siril has put out a fix to the Ventura bug thsi past week ! I've downloaded the new version and ran a couple of sessions and all looks good so far ! Whew!

[@philippeborie4086]

Excellent ! You wrote "Luminance (230*2"), R,G,B (65*2" each filter) Total: 14.2 hours". It's surely 230*2' and not 230*2" or 230*120"

[@NebulaPhotos]

Whoops! Yes, just a typo. Thanks for letting me know, I will fix it.

[@beyondearthimagery4975]

Love the videos nico! Could you do a edit along video of a modified dslr on a target rich with hydrogen such as the Horseheads nebula or California nebula? Thanks

[@WilliamSmith-gf3nt]

Again I am learning so much from you. I have only used SIRIL for stacking but now I need to go back and rework some earlier shots using the SIRIL processing tools you demonstrated here and also GIMP tools that I never knew how to use before this video. We are supposed to have, finally, clear skies for two nights in a row so I should also have new session photos to practice on! One question though is how you obtained the four separate LRGB files. Were these broken down by SIRIL or did you separately process each set of images and if so did you use your bias, dark, and flat files with each set? Cheers and this video will also be watched several more times.

[@NebulaPhotos]

I took data with a mono camera through four separate filters: luminance, red, green, blue. I ran the mono pre processing script with the calibration files four times (once for each filter) to get the four resulting files that I shared here. Hope that makes sense!

[@WilliamSmith-gf3nt]

@@NebulaPhotos Excellent I understand that completely. Thank you.

[@Neanderthal75]

Great! I'm usually very satisficed by the time I get to the point of having the stacked images and only needing the post processing done. My problem is the calibration of mono files, which I am very new to it and my flats/ flat darks refuses to calibrate the stacked files right. I'm talking about my own files of course. I thought I had my experience ready for mono, but apparently not LOL! Also the camera itself maybe have a role in it, with the Panasonic sensor, which I researched and read some very mixed reviews and how it just won't work with just any calibration frames (regarding how long exposure, how many ADU , and probably I may have to do a ritual tribal dance around it a few times. 🤣🤣 I guess I am spoiled by OSC cameras too much!

[@NebulaPhotos]

Ah flats can be tricky, but I'm surprised to hear you are having a big trouble with calibration moving from OSC to mono. What does it look like when they aren't calibrating right, over-correcting?

[@agustinarturoreynososantos1514]

Which filter did you use for the luminance data? Thanks for sharing your knowledge!!!!

[@NebulaPhotos]

I used an Antlia Luminance filter as part of an LRGB set

[@kevinashley478]

Hey there Nico. I was wondering, could you do a video about how to add data to an already processed image? So like if you take 2 hours of data on say, the Andromeda Galaxy, and you processed the data to a final image, but then you gather 2 more hours of data the next year, how would you combine the data?? Do you already have a video on that?

[@NebulaPhotos]

I don't, but I will add it to the list. The short answer is keep all your raw data. You can add to a project later if you have your raw data. If you only have the processed photo, it's not really worth doing IMO.

[@crateer]

Unfortunately I had to stop watching.. way too scary 🧛

[@vampolascott36]

I realize you're an accomplished DSO photographer, but have you ever applied any of your processing techniques on terrestrial clouds? I'm curious about new techniques to tease detail out of sky/landscape shots.

[@mrmelloman5961]

Yes Siri is very bad on Ventura even right now I tried to process my photo and it did not work my laptop crashed a ton (granted I have a 2013 MacBook Air on opcl) but I got boot camp and deep sky stacker and it work very quick and my photos where stacked just fine

[@MultiJp51]

how do you align the R B G L images ?

[@Hughes0302]

I have a question, I have a sony rx 100 vii, is that camera good enough for astrophotography?

[@NebulaPhotos]

I have never used it. On paper, it looks pretty good, so I would encourage you to try it. Make sure to go to a dark sky, focus manually, and shoot Raw.

[@Hughes0302]

@@NebulaPhotos waiting for a clear sky, it's cloudy and foggy these days but thank you for the advice!

[@bulversteher]

I have a unmodified Z6 + Z100-400/5.6, live in a highrise builiding in Vienna/Austria where I can access the rooftop with pretty much a 360° view. A friend in the same building has a equatorial mount he could lend me. Any targets you'd suggest me to look out for it there happens to be a clear night? Any 77mm filter suggestions?

[@NebulaPhotos]

I would start with no filter, and just go for objects that are high in the sky where the light pollution will be not quite as bad. The Messier objects are a good choice typically as they are brighter objects that can compete better against the light pollution.

[@bulversteher]

@@NebulaPhotos thanks a ton!

[@saikattalukder2180]

Hi Nico. I've a question. How should I approach if I wanna stack astro images taken on multiple nights? If I stack images of each session separately and then stack the result autosave files of each session, will it gonna work?

[@NebulaPhotos]

That can work. It is an easy way to do it, but won't technically result in the best photo. There are other ways too. DSS has a 'group' feature at the bottom for loading in multiple nights. With Siril, I'd suggest Sirilic add-on or learning manual calibration / stacking process (not using the scripts).

[@saikattalukder2180]

@@NebulaPhotos I am planning to stack photos of 4 nights. I am afraid that dss would take forever to stack them all at once.
