Hi all, well here is my last image done last night of M11. Not guided, 96 frames of 42.4 seconds, 80mm WO APO LXD650 mount, DSI II Color camera with a full Moon and some upper level haze. But not too bad. The stars are not touched up, they are actually round! I did a bit more adjustments on the RA and some new PEC training and I am getting the error down.

Floyd,
You definitely seemed to have achieved "round-dom" with your stars! Nice color, too. If you don't mind a comment or two, I'm wondering if you didn't clip your black point a bit (I'm at work, so I'm really guessing). I'm also betting that there's more detail hidden there. If you can try a non-linear or curves stretch, it's a better route to increasing contrast and showing detail than overdarkening. There are some good tutorials out there that really helped me. (You can check our Warren Keller's for a start.)
Hope you don't mind my two cents.
Keep it up,
Larry

Stars are looking good Floyd, It looks like your getting the focus down also. what helped me is a motor focuser, just a tap of the button one way or the other. Orion has one the you can adp. to just about any scope. I put one on my Orion 80ed and am going to put one on my new R200SS when it comes.

Good luck

Hi Floyd. I should be the last person to give advice, and this is subjective, but with a little bit of processing, the image shows a lot of "untapped" detail. I took the liberty and processed the image in photoshop CS using Waid's online tutorial on "Star shaping and enhancement", with good results. Also I think the circular shaped 'haze' surrounding central field of image could be eliminated with a sky flat. BTW, the star coloration is quite impressive with you camera considering exposure time.
