NGC2419, the Far Away Globular Cluster (Feb. 2016)


This image is second light with the CFF CC290 f/13.5 at effective f/7.93, guided on the NJP.  This image is 8x720" with the SXVF-H9 and Astronomik CLS filter.  NGC2419 is one of my favorite targets.  At this longer focal length with this size scope, images show the cluster's true nature as a globular.  It's amazing to think of this thing floating 270,000 light years from our galaxy, almost not gravitationally bound to us.  The skies there must look very different from ours!

The bright star above the cluster is HD60771, a magnitude 7.19 A-type star.  There are several small galaxies in the image.

As before, the NJP guided like a champ.  Here is a screen shot of PHD2 (with a misleading equipment name, as I missed one of my spacers when I first figured the effective focal ratio):
