It's M104 season!
Not up to the standard of Lee's amazing image, but it's a PB for me so far. Although F10 / 2000mm is way oversampled with the 183, I use binning which helps. I still think the 8" F10 works better than the 10" F4 for small, bright galaxies. At least with the 183, but still experimenting.
Deforked Meade LX90 ACF 8" F10 SCT, HEQ5 Pro guided with PHD2, ZWO ASI 183mm Pro cooled to -10C, Svbony LRGB filter set, Luminance 369 x 30 seconds, Red, 123 x 30 seconds, Blue 130 x 30 seconds, total 742 x 30 seconds or just over 6 hours of data.
