M 92 - Globular Cluster
Fusion of two images:
1) acquired in 2018-05-11 through my Canon EOS 60Da + Canon EF 400mm f / 5.6L:
376x30" ISO 1600 = 188min;
2) From "One Click Obs" from Telescope Live (IC Astronomy Observatory:
Officina Stellare 700 RC F8).
It is an LRGB image from 2/2/2/2 exposures of each filter for 300" each = 40min;
removal of "hot pixels" and other defects
with PhotoShop and PixelMath in PixInsight...and with the merger.
