M101 from DSC

[Carole]

I took this back in 2016 when I didn't get enough data due to lack of clear skies. 
This time I had a couple of disasters.

only 2 clear nights at DSC and one was misty.

Night 1. I took this with my dual rig ED80 taking LRGB ad Ed72 taking Lum only.
The following day I looked at the data and it was a disaster  the dew heaters had failed on the ED80, and the lum on the Ed72 was slightly out o focus, no idea why checked it beforehand.

Night 2
Wanted to get the blue Horsehead so removed the ED72 and put the Samyang lens set up on instead.  This left me with only the ED80 (with new dew heater) to get more data on M101.

In total I managed to get only a further 4 Lum and 4 each of RGB beore the Blue Horsehead was rising.
A friend blasted the ED72 (out of focus) data with Blur Exterminator, but there was still not enough colour.

In total:
ED80/Atik460EX
ED72/ Arik460EX

Lum 22 x 600 (3h 40mins)
RGB 40 mins in total

Grand total 4h 20mins.
Needed some nifty processing to get a sikc purse out of a Sow's ear.
