NGC 7510

Sky at Night Magazine - - THE SKY GUIDE -

We slip slightly over the bor­der from Cas­siopeia into Cepheus to get to our next tar­get, open clus­ter NGC 7510, which lies 0.5º west of Markar­ian 50. This is a pretty clus­ter, slightly brighter than Markar­ian 50 at mag. +7.9 and a bit larger at 5 ar­cmin­utes in length. It stands out well against the back­ground stars and looks some­what flat­tened into a pat­tern that re­sem­bles the head of an ar­row. It gets this ap­pear­ance thanks to two ap­prox­i­mately par­al­lel lines of faint stars. The bright­est star in the clus­ter has a mag­ni­tude of +9.6. SEEN IT
