How do you evaluate focus when focusing?Jason Boyce said:
I think I missed focus a little.......
Are you using automated focusing?

Cocoon Nebula with E160Posted By dan kowall |
Welcome back, Tyler. That's a great start on the Cocoon.
The E160 sure helps make the most of one's imaging time.

Well done, Ralph.
There's lots of detail there.

Cave Nebula SH2-155Posted By dan kowall |
This is one of your best, Jim.
Great composition and color. You're even showing some of the greyish wisps near the center, which are visible only after long exposures.
Despite the short color exposures, I think your color data is good enough to increase the saturation a bit, maybe give a little kick to the blue?
F/3.3!-you're in the high speed lane.

Wonderful processing, Vincent.
It's not so easy imaging dust.
What was your binning for this shot?

One-shot color image processing: HELP!!!Posted By dan kowall |
You need more than three darks to make a good master dark, Luca.Gianluca Valentini said:
It has been dark subtracted with a median of 3 darks and no other processing:
The software needs more images to properly identify what it bad data.
I would combine at least ten subexposures to make the master dark if I were you.
Sorry, I can't help you with your other questions.

.....I've got to say that I was expecting better results with the exposures I got on this......
On the contrary, Louie, this is a fine result.
I think this galaxy is naturally contrasty, and is harder to process than most.
Your version compares favorably with Jim Misti's version:

for its coloration, etc.

Which color to shoot with young waxing moon?Posted By dan kowall |
I agree with Eric about the red.
If you have an Ha filter, M 31 has some nice Ha areas that add a little sparkle to an RGB.
