Hi everyone,
It is an interesting part indeed, last year I did a shorter exposure with the C9.25 around the reflection nebulae and it showed a galaxy, an emission nebula, a dark nebula, a globular cluster and the dark stuff in one exposure.
I detrail in PSP6 by using the lightest combine and darkest combine commands, so to remove a slight trailing I make a copy from the original image and shift the copy by on pixel in a perpendicular direction of the trailing, and then do a image lightest combine. This way I also reduce the noise in the image a bit, but the resolution decreases.
Alternatively I can do an image darkest command with an in the trailing direction shifted copy instead to do the detrailing, but this increases the noise and resolution.
To maintain the same resolution I usually do a combination of both methods to get the best results.
Cheers,
Erwin
