Camera: QSI 583wsg with Astrodon Tru-Balance E-Series Gen2 filters

Exposure: LRGB 210:125:125:110. Luminance unbinned, 10min; RGB unbinned, 5min.

Calibrated and Stacked with CCDStack2; RGB combine and DDP with MaximDL. Processed with CS4.

The trio consists of NGC3628 (top), M65 (bottom right), and M66 (bottom left). I shot this back in 2014, but was never very happy with it, primarily because my so-called processing skills left a lot to be desired back then. It would be interesting to re-process the 2014 image, to get a better comparison of the SV80 scope versus the Megrez90.
