Description

My HEQ5 was showing nasty 13.6s oscillations on the RA axis - with 4" amplitude. This made all stars egg-shaped. So I bit the bullet and installed the Rowan Belt Mod. It now guides with 0.8". There's still a bit of work to do, probably cleaning and regreasing of the RA axis, but I finally get decent stars on my C8. Eccentricity 0.53 and FWHM of 2.4" in the stacked image.

This is my first project, an easy one: M13 in Hercules. I hope you like it. I have to work on getting better flats to fully correct for those annoying dust motes.
