20170120 Sun

Excellent transparency (Hong Kong standard, of course) 9/10 with quite nice day time seeing at 7/10! However, excessive dust on my CCD renders higher image scale useless... I guess a 3x barlows should be ideal. First up is the full disc shot, with the reducer at 0614 (UT):-

And then two high power shots without the reducer, but with a 5x powermate, taken at 0628 and 0633 (UT) respectively.
