Description

The image was taken with a ZWO ASI183MM-Pro at 4x4 binning with Gain 0 as a comparison with the Starshoot G4 monochrome camera. According to some of the people at AAVSO, binning acts as a 12-bit camera to 4x4 would give the camera a virtual 16-bit ADC. Also, the pixel size of the ASI183MM is 2.4µm and a 4x4 binning would be the equavalent to 9.6 µm, which is compariable to the 8.6µm x 8.3 µm pixel size of the Starshoot G4 (the pixels for the G4 are not perfectly squared). However, I got carried away and went ahead and took subs of M74 with the rest of the LRGB filters. I will, however, post a side by side comparison of the subs of the two cameras later and post it on Cloudy Nights and maybe the AAVSO website.
