Now up to three hours now on this one, and am still banging away with the luminance filter (colour to follow) but have to say I am really pleased with
the quality of the data so far....much of it now with FWHM's well under 2 arc sec.
Time spent doing a proper collimation was well spent.
Given the data was also taken from a city with 4.5 million inhabitants, makes the data even more remarkable.
