Just saw this thread. I have not had much opportunity to use my recently acquired 2600MC. I have done one first light from my Bortle 7 sky in Sydney. I must say it is a fun camera to use and look forward to using it from a darker site.
The attached image was made with my 400mm Canon L lens and Optolong L-Pro filter. It consists of 8 x 5 minutes exposures. I would have liked more exposure to smooth things out, but high level cloud cut things short.
This was a Live Stack and aligned image that was also calibrated (darks and flats) on the fly in SharpCap. I then took the 16 bit stacked file produced by Sharpcap (113mb) and processed it in PS.
