I went back and reprocessed my photo of M27 with a trail copy of APP to see what it could do.  This is a combo of 33x 60 second subs taken with a Canon 60D (FS Mod) @ISO-200 and my LX-90 OTA.  Its not bad, but i am finding that it is harder to get good images with APP than with my other astro program.  Trying to find the right settings to use is like trying to guess a color with your eyes closed.  Anyway, enjoy!

What is your other program? I really like the very modestly priced StarTools. Here is my take on M27 using StarTools.

I use MaximDL.  It lets me automate pretty much every step of the way, from controlling my scope, to taking and processing the photos. Its a little more user friendly too.  Still APP did a better job of reducing the stars to points rather than bloated smudges.  Guess i need to learn how to process better in MaximDL...

What kind of skies did you shoot in (Bortle/SQM)? And did you use the focal reducer? (From the image scale I assume you did.) I ask because I would have expected more nebula from 33 minutes of total exposure. For instance, compare this shot, which was only 8 minutes total through a 6-inch f/5 Schmidt-Newtonian (in Bortle 3 skies). Stock Pentax K-3II.

Yes, i used a focal reducer but it appears to be the chinese made F/6.3 from Meade though not a true F/6.3.  I get around F/4.7 or so out of it and have to crop the image to reduce the football stars somewhat.  Keep in mnd i am still trying to figure out APP so it wasnt as good as an image i got from the same source files as the one processed with both MaximDL and Photoshop together. See below.
