M2 / NGC 7089, globular cluster: unhinged, unguided, unaligned...
...and against the full Moon :)
And for some reason I had tried to use "Polar realign" option of NEQ-6 controller. Never ever touch this button again!!!
Acquisition time: 20.08.2016 22:40 MSK
Equipment:
QHY5L-IIm powered by QHY EZPlanetary on Celestron OMNI XLT 150 mm Newtonian riding and bouncing on the back of galloping Skywatcher NEQ-6 Pro mount.
Aperture 150 mm
Focal length 750 mm
Tv = 5 seconds :(
Av = f/5
Gain... Infinite!
Exposures: some percent of some tens of 5 sec (plus 20 respective dark frames and 50 1 mks offset frames).
Processing: FIT images were fed to DSS. Stacked image was processed in photoshop by increasing gamma to something, brutally clipping black to 45 out of 256 and adding MOAR! gamma, up to almost infinity, again... :)
I had to revisit it...
Flickr added "outdoor" tag... Well, it is very-very outdoor object :)
