2018-05-06 - Prominence Close Up

This is the first time that I have used the fabulous old Thomas Cooke 10" refractor housed in the Marlborough College Blackett Observatory, for solar imaging. Combined with the Daystar University hydrogen alpha filter, it makes for a very efficient system. This image is constructed of two images - one for the surface detail and one for the prominence detail, the two combined in Photoshop. I am extremely happy with the results obtained from the 158 year old telescope!
