Description

I own a 8" Ritchey-Chretien scope that is poorly collimated and last week I made a big effort to try and sort this out.

Last night (29/4/2024) I undertook a star test and made some further tweaks to the primary mirror before slewing around to M51 as it approached the Meridian in the South.
