I've had this data for quite a long time and have only now spent the time to process it. I was trying to image at long focal length with my Celestron C8. I also used this opportunity to experiment with DDP and using deconvolution on a globular cluster image. There is considerable color bleeding that I wasn't able to track down - perhaps an issue with the focal reducer?
