This is a really bright object! I managed to get a 50min exposure during cloud gaps at the last new moon. I think it came out quite well for such a short (50min) exposure. One 10 min sub each of L, G. B and two 10 min subs of R. The annoying thing was that the seeing was good during the cloud gaps. I managed to get an FWHM of just under 2" on the luminosity frame.
Telescope: 12.5" Plane Wave CDK
Mount: AP 900
Camera: QSI 540wsg
Guide camera: SX lodestar.
Acquired in Maxim, processed in PixInsight (Standard stuff: DBE, ColorCalibration, Deconvolution on the L frame, HistogramStretch, LRGBCombine, some histogram and Color saturation tweaks. No noise reduction)
