First ever attempt at a stacked wide field astrophoto, taken early this morning from the backyard, in Griffith (Country NSW)
the tech details:
Canon 400D unmodified
Nikon 50mm 1.8 prime @ f2, ISO800, with F mount / EOS adapter
Fixed tripod
37 x 8 secs sub-exposures
43 x 8 sec dark frames
40 flat frames (zenith at dawn)
43 bias frames (1/4000s)
Pre-processing in DeepSkyStacker
Subtle curve tweeking in Darktable (a linux version of Adobe Lightroom)
DeepSkyStacker - basically went with all the suggested software settings:
RGB Channels Background Calibration
Kappa-Sigma (K=2.00, iterations =5)
Bias: median
Dark: median Kappa-Sigma, Dark Optimisation, Hot Pixel removal
Flat: median
Detect and clean remaining hot pixels
Any tips/advice appreciated
