The data is from february 2020, but the processing is from just now.

I used the XT toolset to completely reprocess 15 hours of LRGB data on this pair of galaxies.

Gear used: SkyWatcher 190MN with ZWO ASI174MM-Cool camera. The camera was discontinued by ZWO a year or two ago. I still don't understand why, because it is a very nice deep sky camera. The sensor isn't large, but the pixels are, and the sensor had one of the highest Full Well numbers when it was introduced. The read noise is quite high, for today's standards, but if you use the camera in "CCD mode", ie with low gain, it performs very well.
