OSC Narrowband Processing - EASY WORKFLOW in PixInsight

Link to the raw image if you want to follow along: drive.google.com/file/d/1OpMb...
It's always good to revisit processing multi-band OSC narrowband images taken with filters like the L-eXtreme, as they provide such a low bar to narrowband imaging! Let's do this in this video!

Hey Cuiv I always enjoy your upbeat presentation style and casual approach. This tutorial was very handy as I've struggled to separate out the colors with my L-Enhance without doing "weird things". I also stack in Astro Pixel Processor which has an option for stacking with these duo/tri filters (I'm not sure how much difference it makes). As a new user to Pixinsight I'm slowly getting used to the "mystery" of it. 🤣 Kampai Cuiv!

I'm watching this over and over until it's pounded into my brain. Random question but would you ever consider 1 on 1 paid PixInsight tutoring?

[@CuivTheLazyGeek]

Mmmh, I know some others have done that, not sure whether I'd be able to find the time for 1 on 1 tutoring - but also I consider myself to be average at PI... Maybe a live stream where people can ask questions would be more appropriate!

[@juno1666]

Cuiv, it is really wonderful to have you back! Was this image shot with the Sharpstar 61? I am just now setting up my Sharpstar 61. Clear weather has not been my friend for quite some time. Have you ever done anything to get better DEC balance with the scope? With the standard small dovetail, I think that the big weight imbalance is a bit much for my AVX mount. I ordered a 9" dovetail that I am going to try to mount on top of the stock dovetail to raise the scope for the focuser to clear the mount saddle. Great image and really interesting take on processing. I have learned so much about PI processing and equipment from your videos (I also have the Sharpstar 61 and the ASI533). Thank you so much and its great to see new videos!

[@CuivTheLazyGeek]

Yep, that's the Sharpstar 61!

[@AnakChan]

Well done Cuiv. One other method I'd like to use to remove green from the stars is to invert the pix, use SCNR to remove green, then reinvert back to normal.

[@CuivTheLazyGeek]

Thanks Sean! Wouldn't that be for magenta stars though?

[@AnakChan]

Doh! Yes . Sorry it turns green in inverted mode but in normal mode, it’s magenta. Sorry.

[@Astro_Ophiuchus]

Hello Cuiv, this is a very good video. I’m kinda new to astrophotography. I just got the WO RedCat 71, ZWO ASI2600mm Pro camera and the Optolong L-Extreme filter for Christmas. My question is, am I going to be able to get the same results using a mono camera? How do I stack the data? Do I use the WBPP? Would you be able to make a video tutorial with a mono camera using that filter so I can learn how to do it? Thank you

Hi Cuiv. At approximately 7:50 you mention your GCU and that you haven't yet set up StarNet2 to use the GCU. Can you make a video on how to do that - or perhaps provide a link to an existing video. I just bought a dedicated GCU (an upgrade from my integrated GCU) and was wondering why I haven't seen any performance improvement in my processing. Could this be why? Huge fan btw! Thanks, Tommy

Hi! Completely new to PI, moving from an APP & Photoshop or Siril & Photoshop processing workflow with my OSC 4nm data to PI. Also will be picking up a mono set up for a 2nd wide field quad telescope. I feel that PI is the next big set up - just tried to download the Follow Along files but file not found - can these be made available again? Thank you!

I don't even have Pixinsight, but regardless I'm learning to use it haha! Once, I will purchase , then cry for a whole week for the money I spent and start using it.

[@matthilton8959]

What did you stack in? When I use this filter my starting data is pretty much red. Yours from the offset looked blue and red. How did you manage that?

[@CuivTheLazyGeek]

I stacked in PixInsight using batch pre-processing. I have no idea how the color came out like that to be honest, it just did!

[@endolf]

I just setup PI to use my 3080ti for starnet under linux this evening. Gone from 1m13s to 9s for QHY268M sized images.

[@paulwilson8367]

I have the same throttle quadrant sitting in front of my computer, and also the yoke and rudder pedals. They don't much get in the way of the processing. I fly the XPlane 11, Zibo Mod 737, the aircraft I flew for many years on the line as a commercial pilot. Now I listen and struggle to absorb videos.

[@CuivTheLazyGeek]

I've recently been addicted to MSFS2020 - the visuals are just too good, even if the flight model is worse than X-Plane (at least on the default airplanes!)

[@komr323]

Usually I split the rgb after stretch and enthesize the green channel, replacing it as blue, then green is 60% red + 40% green. Your way should be able to control the noise level better. What do u think?

[@CuivTheLazyGeek]

Mmmh true you'd likely control noise level better, but I really wanted to not go into separating channels!

[@astrobob9432]

At the beginning of your video, just to your right, it appears you have a miniature aircraft power control console, with power or throttle lever, prop/rpm lever and mixture. For a simulator/game?

I used to have all the flight sim gear but sadly my poor old PC isn’t up to the job these days. You must be getting some practice in prior to making your triumphant return to the skies!

[@CuivTheLazyGeek]

Oooh yes, PixInsight is well worth it! And for this particular image, I didn't even have to think about Ha, SII, or OIII - just straightforward manipulation. Yep, doing flight sim in VR, it helps scratch the itch for now :)

[@Kyle_Hubbard]

@@CuivTheLazyGeek As I suspected. A lot of KZbin astrophotographers seem to have equipment what feels like every few months. I appreciate the response. I have one last question if I may? I'm looking to get my first astro camera and had been considering the 533MC over the last six months (Didn't have the funds at the time) but from what I can see there are newer cameras in line with the 533. Like the 294MC. If you had the budget for a 533 plus a couple hundred more what camera would you get? Where I live the 533MC pro costs 900 but the 294MC pro costs 980, it's only 80 more than the 533MC pro, it's not that much more. Opinion?

[@AstroDenny]

This is great- I can say that I do not get results like that with the L-eNhance and the L-eXtreme doesn't work well on f/2 optics. I will experiment with this technique a bit and see if I can get that nice color you're seeing.

[@derekderek2570]

I do feel like the LeXtreme wasn't advertised in a way where it was explained that it's basically useless to faster scopes. at f/2 you're getting less than 10% of the light... even at f/5 is drops dramatically under 50%...really anything after than f/8 you're losing a substantial amount of data with the LeXtreme. The L-eNhance is better by about one or two F stops but then you're having to deal with those flairs on bright stars and those 'less than excellent' bands that you get on the LeXtreme. It's always a give and take in AP (Unless you drop $1000 a filter on some Chroma's)

[@CuivTheLazyGeek]

The IDAS NBZ is probably great for you!

[@CuivTheLazyGeek]

On thing to keep in mind though is that these transmission figures affects light hitting the outside of the telescope objective, but light rays coming near the center are unaffected. Effectively you are reducing your aperture, but it's not as dramatic as losing 90% of the light all around.

[@derekderek2570]

@@CuivTheLazyGeek interesting...I actually had a gut feeling that might have been the case but have been too lazy to go into research mode. Does that mean if your target sits nicely centered it won't have such a large effect on lost data?

[@CuivTheLazyGeek]

@@derekderek2570 No, the light rays are parallel when they hit the objective lens - so it's not about where the target is in the field of view at all, e.g it doesn't cause vignetting. It really literally means that light rays that hit the outside of the objective will be transmitted less than light rays that hit the center. Effectively you're applying a mask to your telescope, and that mask gradually let's in more light at we get closer to center.
