Description

My first look at this beautiful cluster with the CCD camera and RGB filters. I last imaged it about 5 years ago with a DSLR camera.

Title: Reprocessed using PixInsight.

Description: There are lots of strong star halos in the data, that I previously hid by only applying a minimal stretch and lowering the background. I still had a lot of issues using PI, but decided that the stars look better (shinier) with the halo glow than without. I experimented with the clip factor and background level in MaskedStretch to try to balance the halos and background.
