Comments, Observations

Nowhere near the best image ever taken of this object but probably as good as I can get here in heavily light-polluted Tempe, AZ.

Finally made some sky flats and applied them. That made a BIG difference! It got rid of red green and blue dots caused by "hot" pixels generated by the imaging chip and got rid of dark spots caused by "cold" pixels generated by the imaging chip. Also any "dust donuts" were eliminated - There was only one tiny one and it was not being seen in this image anyway...

I used handyAvi to make 5-minute sky flats. HandyAvi has an option to move the telescope about in a square during the process so that stars do not get captured in the image...

Still not sure what happened in upper right corner. Don't think there should be a bright area there... Maybe need to do sky-flats again?

Here is the best I could do before generating the sky flats:
