This image is a stack of three, four minute sub
exposures calibrated with flats, flat darks and darks. The SNR is
rather poor as the image was taken under rather light polluted
skies. There was a 20 KPH breeze during the session and the
mount handled it well.
Calibration, stacking, background noise
reduction and initial star size reduction done with Images Plus .
Background correction and further noise
reduction applied in Paint
