Big Spot


Sunspot 1754 photographed 11.00 am 27-05-2013 from my backyard, using a QHY5v planetary camera attached to my 13 year old ETX 90Ra Mak. AVI clip stacked using AutoStakkert and then manipulated in IRIS and Photoshop. The spot is very visible as it is quite large, in fact the Earth would sit comfortably within the umbra. The 'orange peel' appearance of the photosphere created by convection cells is quite apparent. I know the technicolour APS approach is not for everyone but I quite like it!

I thought my old ETX did well for its age.
