Description

SH2-171 part of NGC 7822


Clear skies are very limited here now.

The combination of larger aperture, 0.66x reducer, and bin2x helps get better SNR in shorter time.

Camera gain was at 56 with read noise at 1.5 e-.

The 3nm also help with better contrast from Bortle 6.

Data from the 4th to 9th of December over 3 semi clear nights.


At newer version of this object was aquired with the larger CDK14 telescope here:
