||40 minutes (40 X 1 minute)
||Canon 60Da DSLR
|| 200mm SkyWatcher f/5 Newtonian reflector with
Paracorr for a total focal length of 1150 mm
||St. Croix, Nova Scotia
||Calibration and stacking done with Images Plus.
No darks were used in the calibration as the 60Da has built in dark
suppression. Statistical filter applied for reduction of the fine grain noise followed by an arcsinh initial stretch. Feature mask function used to
separate the stars from the background. The background was stretched
with a curve adjustment and then sharpened using multi-scale
decomposition. The stretched image was then recombined with
the stars and the halos reduced with a masked curve.
