The two images below are of M16, the Eagle Nebula. One shows the Sharpcap screen while stacking and the other shows a final screenshot of the stack. The second image is cropped to reduce the size for posting. The camera used was the ASI 294 MC and the scope and mount are as listed in my signature. Skies were decent that night and I was subtracting darks.
As you see, the stars seem way too large and partially mask the ‘Eagle’ and generally detract from the screen capture. This has been a common issue with my beginning experience with EAA and Sharpcap and I can’t seem to figure my way out of this problem and hope some of you experts out there might help me learn what’s going on so I can solve this issue.
You can see the primary settings in the Sharpcap screenshot. The scope has decent collimation when I test it before the session but the Svbony helical focuser I use has internal ‘play’ and the camera is not solidly fixed in the focuser so some wiggle is possible when setting up and, getting the camera a bit off axis as a result, might be happening. I don’t want to presume that’s the issue though.
Please offer any ideas or suggestions - they are much appreciated.
