For those interested, here is the gear I use (or equivalent; Orion has discontinued some of their products, so the equivalent skywatcher products are listed). Most of the links are Amazon Affiliate links. Thanks!
Skywatcher HEQ5 Mount amzn.to/3NVrVQi
Skywatcher 80mm F7.5 Doublet amzn.to/47mbfZi
ZWO EFW mini filter wheel amzn.to/48OxhoN
Optolong LRGB Filter Set (1.25") amzn.to/47r23Tw
Orion 0.8x Reducer amzn.to/47s64a4
USB RJ45 Cable for Controlling Mount amzn.to/4aPlIzu
Raspberry Pi to control mount amzn.to/48mTBWH
R Pi case with touch screen amzn.to/3HvdNKl
ZWO Autofocuser amzn.to/3Skg0hX Last week, I did some live stacking on RU-vid of M51. In this video, I process those data using free software (Siril, Gimp and my sharpening tool), showing how I did it.

Remember, the tool is still in beta for the web version. Only 600kb , BW, no alpha channel images can be uploaded. nqFI29h8W0Fp9UkKOJry

Very nice, I have yet to figure out your sharpening tool. I tried to upload a B&W downscaled tiff file I took of the horsehead nebula. It was under the 800Mb limit yet it kept giving me an ERROR.

Very nice! I have yet to figure out your sharpening tool. When I upload an 800mb B&W tiff image of the horsehead it either disconnects from the server or gives me an ERROR message. The image was pretty noisy, would that mess up the sharpening?

Thanks! So right now, the tool can only accept 600kb images (which is pretty small). They also have to be black and white with no alpha channel. That's the limitation of the free web server I'm using. Hopefully in the next week I'll have a standalone app that can be downloaded and you can upload any size image (as long as you have enough ram). It will still be limited to monochrome images (probably).

This isn't a critisism of any kind, (you got my sub so hopefully that indicates my intent). At what point does an image stop being astro photograph, and become computer generated art? I promise I'm mot trying to insinuate anything, and I'm by no means a purist when it comes to my own photography, I'm just interested if you have thought about this, and where if anywhere you'd draw a line (between astro photography, and Computer Generated Art)?

That is a good question. You can make AI tools that create new data. I think some denoising tools can do this because they are too general. Take an AI tool that was trained on cat pictures, and you might start getting whiskers in your astro images. The thing about this tool, is that the training data is very constrained. Meaning, during training, the input is a blurred set up pixels, and the output is a sharpened one. After training, learning stops. The neural network is now just one mathematical formula, and the functions will be applied to any image in the same way. It's like a deconvolution matrix, but implemented in a way that takes into account patterns of blurring. But you don't have to just take my word for it. If you like, you can try it on your own astro images (if you have them). Compare the original and the new image and look for things that might be off. Then, let me know what you find! If you think it works, great! If you think it's creating things that aren't there, that's still great if you tell me about it :) I can then try to improve things!

I just realized you might be also talking about the processing in general (not just the sharpening tool I used). I think this deserves a really detailed answer. I might make a video on it sometime. But the short(ish) answer is this: 1) Digital cameras measure photons linearly. Meaning, a pixel that is 2x brighter than the other probably had 2x the number of photons hit it. 2) Our eyes do not see linearly. Our brain automatically adjusts for brightness. Sometimes in pictures, you'll see that part of the image is blown out even though the rest of the image is fine. You can see both areas in a way that isn't blown out. 3) This is why we need to stretch the image. It helps bring out the fainter details that (if our eyes were sensitive enough) would look kind of normal 4) Many of the techniques used are indeed subjective (adding high pass filters; color calibration techniques etc). But that is true of other photography too. 5) I don't think most astrophotographers' goal is to produce a scientifically accurate image. Rather it's to produce a pleasing image that brings out the underlying structure of what they are looking at. So, do I think it is computer generated art? Not really. Not like what DALL-E is doing. The picture has real data in it, and the processing helps us see those data.

@@superearth5256 Yeah, I think that if the exposure is too short, then there just isn't enough signal to pull out detail. What kind of setup were you using if you don't mind me asking?
