Using a borrowed 70mm Altair Starwave triplet refractor fitted with a 0.8 x FR (courtesy of Anne Startup) I did some more imaging; this time of a galaxy, a star cluster and a nebula. The night was dominated by one of the strongest and sustained displays of aurora which covered most of the sky and at one point was so bright it was easily visible with the naked eye. As beautiful is this display was, the DSO imaged were full of aurora which required considerable effort to remove them. A mobile phone and a Sony A77 milc camera were used to snap the aurora as it changed colour; one of which shows the scope in operation.

Aurora Borealius
M45: 4 hours of RGB
NGC 6823/ NGC 6820: 1.4 hours of SHO and a further 1.4 hours of RGB. Three versions were produced; an RGB one, and SHO one with RGB stars and a combined blend of the two
RGB
M51: an hour of RGB
The DSO images were all captured in NINA and processed in Pixinsight/Adobe Photoshop 2024.
