Because of the grainy nature of the exposures taken with the SXV M8C
in MaximDL, I have found that I get the best results in this program
if I use the following procedures:
1. Open image and calibrate for flats.
2. Convert RGB with Y offset checked.
3. If vignetting still bad I split tricolor and autoflatten each
frame. Then I recombine color.
4. Open "Permanent stretch" and set the Gamma for Max pixels and
adjust for a dark gray background.
5. Save as Fits.
6. Repeat procedures for all exposures for combining.
7. Combine images. I use auto one star and either sum or average.
On the combined image I open Permanent stretch and repeat step 4.
The gray image is important. You cannot see much detail here but
when you do the following the image comes out in a most pleasing way.
8. Save summed image as Fits file and as TIFF or BMP with
9. Open image in Photoshop CS and repeatedly adjust the
contrast/brightness until the image is adjusted to your satisfaction.
These steps give the most pleasing background without the grainy
sandy looking background.
I would appreciate any comments or suggestions that would improve
