Description

One of my favourite open clusters and perfectly placed in the sky at this time of year.
We don't get many clear nights in Northumberland and this was no exception!  The session began well but high cloud soon began to creep across the sky.  I salvaged 27 frames taken over the course of an hour with the RedCat and ASI533 camera.  Processed in PixInsight with some of the brighter star cores tightened up with StarSpikes Pro in Photoshop.
