Description

Newton is back, a few weeks ago I screwed everything in a pathetic attempt to collimate and align the secondary mirror ... a disaster!

It took 2-3 hours to fix it.

I highly recommend the use of a concenter to place the secondary mirror at the proper place, also thank you to astro-baby for her excellent tutorial
