imaged NGC 6946 again (Halifax)

BGO imaged NGC 6946 for me. I continue to monitor the supernova in the Fireworks galaxy. SN2017eaw is still fairly bright and plainly visible (despite the tracking issue).

supernova SN2017eaw in luminance

Luminance only, 60 seconds subexposures, 10 stacked shots. FITS Liberator, Paint.NET. North is up; east is left.

I will add this to the data from 11 Jul '17.


Didn't know that in mid-August the BGO image scale was changed. This is the last shot of NGC 6946 with a frame size of 1536x1536; subsequent shots captured at 1336x1336 pixels by default.
