Description

This globular cluster was imaged to utilise telescope time after a prime target disappeared into a neighbour's trees and before the next main target rose sufficiently above the horizon.

LRGB imaging is challenging in an urban environment and the new Pixinsight NormalizeScaleGradients was very useful in helping to remove gradients caused by light pollution at different angles and times during subframe acquisition.  Otherwise processing was a conventional Pixinsight LRGB workflow.  Final noise reduction and sharpening of the JPEG image using Topaz DeNoise AI.

Images acquired on nine nights from mid-December 2021 to mid-January 2022. All 180s subframe exposures with camera cooled to -10C (this period was unusually warm) -- L:138, R:21, G:19, B:32
