Description

Earlier this week I imaged some RGB and Lum subs of M98. Clouds rolled in and ruined the complete set of 60 Luminance subs so all I got was the 20 each of RGB. Not a whole lot of subs to work with, and with short 60sec exposures the amount of data was really low - in fact, only about 20-80 ADU over the noise level of 500. But I was somewhat pleased with the results, so here it is. Yet another DSO for the M110 TSS contest, and yes, I will image this again with much longer exposure and integration time (and with Lum subs!!)

I also conducted an experiment with processing this with and without dark calibration frames. Details at: http://skyandrockets.blogspot.com/2021/06/darks-vs-no-darks.html
