Improvements to your PST!

Post by Merlin66 » Sun Sep 23, 2018 10:30 pm

Sylvain Weiller, well known for his excellent images with the PST, has fitted his PST with a x1.5 photographic converter, which he claims has increased the focal length from 400mm to 600mm and gives better definition and resolution.
Interesting!!!
