Description

My first attempt at an H-R diagram using the AperturePhotometry script in PixInsight.

I was able to graph about 2400 stars. There are more shown in the main sequence area than usually seen in professional H-R graphs (see the Wikipedia article on Globular Clusters about half-way down the page). So far, scaling the variables hasn't done much.

Description: A much better version of the H-R diagram using Astroart 6.0. It still looks slightly rotated relative to commonly shown professional diagrams.
