Description

M42 imaged with C11 XLT and Canon EOS RP(a). A difficult target at this focal length with this instrument but finally one M42 I am happy with that isn't a 'hot mess'   The f/6.3 reducer takes the scope from f/10 to f/6.3 and the focal length from 2,800mm down to 1,700mm. I shot the following unguided. 250 x 15 seconds, 45 x 30 seconds, 4 x 60 seconds. I also shot some dark, flat and bias frames and stacked them using DSS.
