Description

The Crab supernova remnant (Messier 1), imaged in LRGB with Lacerta 250mm f4 PhotoNewton and ZWO ASI183MM Pro camera over several nights in October-November 2019. The L and RGB channel images are stacks of 20s exposures taken at camera gain 200 and 110. To reduce the effects of poor seeing (this season was not the best as far as atmospheric quality is concerned), only selected exposures with star FWHM<3" were used in the stacks.

L: 257x20s (Gain 200, bin 1x1), 52x20s (Gain 110, bin 1x1), 32x30s (Gain 110, bin 1x1)

R: 846x20s (Gain 200, bin 1x1)

G: 241x20s (Gain 200, bin 1x1)

B: 214x20s (Gain 200, bin 1x1)

Total exposure: 9.2 hours
