Hi, I want to thank everyone who has responded to my previous post. I got some very good information and web sites and I really appreciate it since I am in learning mode with NB imaging. I got an additional 5 hours of SII and an additional 4 hours of OIII and reprocessed my earlier image. I have posted the original image and the reprocessed image at the URL below. I would really be interested in which one people prefer. The original image is a softer image with more blues, which I personally like. The reprocessed image has much more red (due to the added SII data), at the expense of the blues. However, the reprocessed image seems to have more detail to me and less noise. It is a tough choice and maybe I should just post both but I would be interested in what people think. http://www.azstarman.net/NGC2264_NB.htm Thanks, Bernard -- See message header for info on list archives or unsubscribing, and please send personal replies to the author, not the list.
