Vertical format shot framing M52 cluster at top left, NGC 7635 Bubble Nebula left of centre; NGC 7538 right of centre at top, and Sh2-157 faint large nebula at lower right. Stack of 3 x 14 minute exposures with Borg 77mm f/4 astrograph and Canon 20Da camera at ISO 400. Some haze in last exposure.
M52 and Bubble Nebula area, taken with TMB92mm apo refractor with Borg .85 Reducer/Flattener for f/4.6. Taken Sept 29/30, with Canon 20Da at ISO 400 for stack of 4 x 12 minute exposures. Mach 1 mount and Orion autoguider and PHD Guider used.
This is the mis-matched pair of globular clusters in Coma Berenices: M53 at top, a modestly bright and rich cluster, and NGC 5053 at bottom, a dim and sparse globular. This is a stack of just 5 x 8-minute exposures with the Canon EOS Ra at ISO 800 through the SharpStar 140mm refractor at f/6.5 with no field flattener.
