Great Video Nico, I just used the Siril-Gimp method on the Horsehead nebula and it worked great. One thing I do differently though is the stars layer. I run the image with the stars through Starnett to get a starless version. I then bring it in as a layer above the stars layer. I then used the “Subtract” mode on the starless layer to get a stars only layer. I make a new layer from visible and then erase the stars and starless layers. I change the stars layers to screen and voila, a stars only layer that can be reduced by playing with the opacity.

Hi Steve, One way to do it is the way I show here. (It's my favorite method, but of course there are many way). To sum it up: Just layer in your registered Ha and OIII stacks and colorize them to taste, screen blending the OIII on top of the Ha.

I know the thumbnail suggests a comparison. Maybe a mistake, as my goal was to show how to get to a similar result in each of the programs, but making them 'match' would just be testing the skill of the processor (me), and I could make them match exactly. So I decided not to include it. I'd encourage people to pick the workflow they enjoy the most. Any of these combinations can produce top-tier results with practice.

If by any chance it was the SV220, how do you rate this filter (note I have a full spectrum A7iii and use a camera lens with a max filter thread of approx 67mm, min aperture of f2.8)? I'm looking at maybe getting this, but its close between the zwo dual band filter and the SV220.

@NebulaPhotos 8 ай бұрын
Yes, with an image like this one (wide field, lots of nebulosity) I’d probably start with ABE and only use DBE if needed. I wouldn’t use the defaults in ABE for a photo like this one. The most important thing is to change the function degree from 4 to 2 so that the background model doesn’t overfit. A function degree of 2 or even 1 will create a nice smooth background model which is usually what we want when dealing with fairly linear gradients. But I’d likely also increase the sample size and spacing (30:30 over the defaults of 10:10?), and I like starting with a ‘Division’ extraction rather than the standard ‘Subtraction’ which is only necessary for tough cases.

One more question, if I might.........no color calibration used? Spectrophotometric Color Calibration?
@NebulaPhotos 8 ай бұрын
I don’t use color calibration when I shoot with a narrowband filter(s) because I know that I’m going to alter the colors to my taste anyways. I know that they have a ‘narrowband’ routine in there, but it’s not for me. I do use photometric or spectrophotometric calibration when I shoot broadband (OSC or LRGB).

Great video, I wasn't aware that siril's script for extracting OIII and Ha does something other than just splitting R and G channels. I wonder if the snr is better with siril's script, I find in my case that blue channel is just way too noisy to be combined with green channel (at least in my case with a dslr). Another testing idea when it gets cloudy! Thank you!
@NebulaPhotos 10 ай бұрын
They use some fancy math (see the note mid-way down this page): siril.readthedocs.io/en/latest/processing/extraction.html I often just use the green channel too, but I do think Siril's way of doing it is likely superior. Of course, it may depend on light pollution level, so testing is great idea!

Hey Nico, great video as always. Any reason why, on the 1st scenario (Siril), you do not create a star mask under the Starnet "plug in" to isolate the starts instead of getting the stars from the HOO image? Would have bene great to get your conclusion opinion comparing the results of hte 3 versions.

It depends on the image, but typically I don't use a 'stars only' image as I find the blend is more seamless by not doing that. So just my personal preference.

Would this work with images captured using a tri- band filter specifically the L-eNhance. Also, I am currently using DSS with Affinity Photo for processing, would I be correct in assuming this would work in more or less the same way as DSS + Photo Shop?

I prefer DSS over Siril for stacking because the workflow is much easier for stacking multiple nights that have their own calibration frames.

It is the linked stretch (default) that is green. An unlinked stretch should show normal colors because you are allowing the autostretch to color balance - apply different amounts of stretch to the red, green and blue channels to normalize them. Open screen transfer function and make sure the link icon is not active, then reset your autostretch and stretch again and the green should be gone.

So I don’t think it is the amount of data. But when I stack the data, and go to process it in Photoshop, Siril, etc. I can’t see anything.

Because right now it looks like I am taking pictures of a blank, black sky. Thanks!

It's normal for the photo to start black out of DSS/Siril (24:50). My guess is you are not stretching it enough to see what you've captured. In photoshop, just repeatedly use 'Levels' moving the middle slider to the left until you see something. Check out my start to finish tutorials for more detail on some of this. If you are sucessfully stacking that suggests you are in-focus enough for the stacking software to find stars, so my guess is you just need to work on stretching. Another idea: in Siril open histogramTransformation, click the autostretch button, click apply. What does it look like?
@christopherpsaros766 10 ай бұрын
When I click apply, I can’t see any nebulosity, or galaxy, etc. it just brightens the background.

If you are on target, and are really seeing nothing in 90 minutes, maybe there is something wrong with your calibration. If you can't figure it out, send me an email: nicocarver at gmail dot com

Hi Nico, is it worth trying your Photoshop portion of this, despite the fact that I cannot eliminate stars? I cannot open/use Star Xterminator (I purchased the plugin before realizing that my system doesn't support it--CPU issue). Could you offer any advice on other ways to remove stars, if any? Thank you very much!
@NebulaPhotos Ай бұрын
Same issue with Starnet? If neither Starnet nor StarXTerminator work, the old way of removing stars was with multiple passes of Dust and Scratches filter, it's not as effective, but can work - look up 'JP Metsavainio tone mapping' for the technique.

Tip: Have your photography equipment set up September 14th by 5:30am and pointed to 71° azimuth. Have a tracker that can follow horizontally north to south at the Earth's current rotation speed for that along the horizon. Not sure how that works but you do. You might get the shot of a lifetime of a bizarre phenomena that I witnessed the morning after Leonard passed between the earth and sun and right before the sun rose. From our perspective p/1 will appear to travel horizontally toward the sun. Nobody believed me when I told them what I witnessed but it makes sense because the tail flips (from our perspective) and the Earth's rotation makes it appear as though it's travelling north to south and rising at the same time until the sun rises and dims it out. It is indeed a strange sight! You have better equipment than I but I will try to catch it if it's clear north of Chicago. Heads up!!

This is what I observed from northern Illinois the morning after Leonard passed the earth/sun zenith plane. It goes quickly so be prepared. kzfaq.info/get/bejne/ataAktWgvKizc6M.htmlfeature=shared

Hey Nico, i have an off topic question...so, what is the thing called, the rings with the mount that you put a telescope/camera lens, in to mount it to the tracker?
@NebulaPhotos 10 ай бұрын
Not sure what you are asking. The rings are typically called rings. The rings attach to a ‘dovetail plate’ which is clamped by the dovetail saddle of the mount.

@@NebulaPhotos ah, ok. Thank you! I just needed the names of the individual parts. So for example, I recently purchased a little 70mm MAK. Nothing spectacular, but i have been able to see great images of saturn and jupiter. I would like to put it on my SA 2i, but the "dovetail plate" that it came with is about 3 inches long....and thats being generous. So based on what you said, I need a dovetail plate and rings. So, I assume that i get rings based on the exterior diameter, right?

Anyone know a good place to buy a Dual Narrowband Filter for a 58mm lens
@NebulaPhotos 10 ай бұрын
You have two options: 1. clip-in filter like the optolong l-enhance clip-in if you use a Canon crop sensor body. 2. use step-down rings with a 48mm filter like the Svbony SV220 (tinyurl.com/svbony220) I used for these images. From 58mm to 48mm, the vignetting won't be too bad, just a little crop.

Pixinsight > Photoshop > Gimp Pixinsight has so much flexibility. By the way, O3 real color should be greenish. 500nm is exactly that. In biology, 488nm on confocal microscope laser is assigned to green.
@NebulaPhotos 10 ай бұрын
Yes, I know, but aesthetically red+green looks really ugly IMO. And since narrowband processing already messes with color balance, I don’t mind changing the colors to taste. If you want to stick to ‘true-ish’ color this whole scene would look just red because the OIII is too weak a signal.

Hi, I have seen the narrowband processing for nebulae, and I am currently looking for a topic for my doctoral research where I can apply "Deep Learning." This field of astrophotography is quite appealing to me. Would it be possible for us to have a conversation, and you could explain to me from your experience the potential areas in which AI can assist in astrophotography?
