I shot over several nights from August to mid-September, it lay around for a long time, a lot of work on it and also the vegetable garden. Processing features: 1. Laida SII 5 nm filter on a color camera, I didn't bother, extracted the L channel and used it for the SII channel. 2. I didn't like the stars from SHO, so I used HOO, on a too bright blue background, the stars still remained bloated, so I slightly suppressed their brightness.
So, I should have taken flats, but I took this shot without them.
Even so, it turned out almost fine, just needed a little tweaking in the software.
The light pollution in the narrowband isn't too bad; it's when you're shooting galaxies that flats are absolutely essential.
And how should it be? If you choose the "Photo" preset, both saturation and brightness increase. But you can't sit at the monitor like that for long—your eyes start to bulge. That's why most people use the "Custom" preset with moderate brightness and contrast (above average). You, it seems, went to the trouble and applied restrained processing in the right settings, which unfortunately looks a bit dull on most monitors.
The Veil Nebula in photo mode does indeed look very saturated. However, even without considering that, there are "clumpy" areas. But I didn't do any processing there at all.)
Would you like to combine the signal? I'll send you the stacks, and we can collaborate just for fun. It'll be 36 hours total. Not 50, of course, but the noise should be reduced by about half, and the details will be a bit better.
Let's give it a try. I'm curious to see how it turns out, and I'll also learn how to combine different sessions.
Just send the data channel by channel, and it would be great to have clean stacks without any subsequent processing.
