Before you go for that large Newtonian think first about the time it will need to be re mirrored.

If I could afford the mirror in that video, I reckon I could probably afford the costs when the time comes to redo the surface. :)

In another video out of Scotland on the mirror process the guy said they do it every two years...I wonder if that is the norm.

During a 2 week window with boards open to NSW I managed to have "Zamar's" mirror recoated by Palmway Optical with the 98% enhanced coating. It was picked up Thursday and returned home safely on the following Monday . The original coating was 22 years old. 2 years sounds ridiculous for amateurs unless it was silvered.
