Tracey and I spent four nights (five days) up at Cherry Springs from the Saturday of Memorial Day weekend to the following Wednesday. I had the opportunity to image most of all four nights while Tracey worked on competing her AL Messier list.
On the last two nights I decided to try imaging with my small Celestron C6 SCT without any focal reducer or field flattener to see how it would do. Here is one of the images I took on Tuesday night.
