revisited Arp 133 (Halifax)

Returned to Arp 133 centred on NGC 541. The Burke-Gaffney Observation produced a much better image than my first attempt on 30 August.

galaxy cluster centred on NGC 541 in luminance

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


Tried again on 20 Nov.
