NGC 4656-My stars look any better now?

Hello again!

Im still trying to get the MPCC+camera to sit flush and flat in the Moonlite (thanks to the inset lip on the MPCC), and have had trouble getting my stars to not look oblong.

I adjusted it and played with it lastnight and decided to try to image and see how it turned out.

This is NGC 4656...and Ill go ahead and say HAD I KNOWN that this is usually taken with 'The Whale' galaxy I would have done it, but since its not listed in the New CCD astronomy tool thingie from Ron, I couldnt see them together to know!

It was only AFTER I had imaged this and did a google to see how mine compared to others that I realized this is the 'Hockey stick' that accompanies The Whale. grin.gif

Anyways, Im hoping my stars look better but I was curious what others might think.

Here is NGC 4656.

4x300 Lum with flats and darks.

They look small and button like to me. In fact just dandy, but why not show the comparison between this, and the image with the dodgy stars.? As I say, these look fine, but it would be good to see the improvement you have achieved compared to the other one.

Ron.:D

Good point Ron and thank you for the help.

I created a thread here showing off how my stars were oblong on my IC 1396 a week or so ago in the equipment thread, it never occurred to me to post a comparison-youre a smart guy!

Here is the oblong stars in my IC 1396 to compare with.

Im sorry. I forgot to mention that others have told me they think it was my guiding, tracking...or the fact that I did not weed out some of the bad exposures on that IC 1396 which I think was 24x300 seconds.

This next one is where I tried to weed out the bad exposures more and redo it again with less than the original 24 exposures. I forget how many are in this but I took out a bunch that I thought were BAD exposures.

Others have said THIS IC 1396 looked like the stars were better, but I didnt adjust anything, I only removed what I thought were some of the 'bad' exposures.

Here it is again with some of the 'bad' exposures removed:
