Like M57, M27 also holds some very dim surrounding nebulousity which shows up well in Ha. I've been gathering data for M27 that now has 14.5 hours Ha, 8.5 hours RGB (170 minutes each), and 10-1/3 hours luminous. The equipment used is a 12.5" f/9 OGS RC and STL-11000M camera. I'm not certain what processes to use to bring out this surrounding dim detail. I've combined the RGB data as well as the Ha and luminous and made the necessary background adjustments using ABE which did very well. At this point I'd probably make a star mask for each and try some HDRW processes. I'm wide open for any suggestions on what else to do or not. I'll post some results of the masters later this afternoon but thought I'd ask before leaving for a while.
Thanks
