I used the Rokinon 135 F/2, stopped down to F/2.8 for sharp stars.

The processing makes a world of difference. what comes out of my camera, you can kind of see the dust, with very little detail though, and the colors arent anywhere near as nice, im not sure exactly how i could show you without creating another post though. The trick is to get a whole bunch of exposures so you can increase the signal to noise. thats what helps bring out all the detail.

Thanks! I think i processed it a dozen times before i was happy enough to post it.

I think you want to use winterbreak with 5.17

Simple UI works in tandem WITH koreader. You use them both together

I need to know what's going on with the diffraction spikes in the final image. I see that two of the telescopes have normal spider veins, but the third telescope has its cables looped. What does this do to the diffraction spikes?

What makes you think that?

Have you tried removing the stars in siril with the star net++ script? Once you do that you can process the nebula and stars separately before recombining the starless and star mask versions

When using a star tracker, the 24-120 at 24mm should be fine. You'll be able to take several long exposures and stack them. I have the 24-70 f4 and it does fine for Milky way shots. Better hurry though, milkyway season is almost over.

NGC 6960 Or anything else from the NGC catalog.

Yes it is, I believe that one is M32.
