A favourite winter target.
Due to cloud, this was only a 25 minute integration (5 x 5 mins) taken at ISO 800 with a Canon 60Da fitted with a Hutech LPS filter. Id hoped to get about 2 hours of data.
480/80mm refractor with x 1.0 field flattener ( a small bristle from a blower brush, accidentally stuck on, caused the diffraction spikes!).
Ioptron ZEQ25GT mount with SSAG/PHD autoguiding.
Backyard EOS camera control and PHD/Backyard EOS dithering.
18 darks and 40 flats (1/20s at ISO 800).
Post-processed in PixInsight and Photoshop.
Ive been at astrophotography for about a year now – my first attempts were with the Pleiades:
Canon 5D mark II and a 70-200mm f4 IS L lens, wide open at f4.
A single 30 second exposure on an alt-az mount.
