Default Advice re Solar Filters.

Using my CP 995 and my ETX 90 is it possible to take photgraphs of the sun using a Type A Solar filter or is it neccessary to have Type C for photographic use. Any tips : hints would be appreciated.

Geordie, could you explain a type A and a type C solar filter? the only ones that i know that are useable for solar photography are the glass or mylar (glass is better) that fit over your scope's corrector lense. the filters that screw into an eyepiece are very dangerous to use. i had the experience of one cracking from extreme heat while viewing through it. it's not pleasant.

The type of filter that I am attempting to describe is a glass filter which has been specially coated, ( mirror effect) on both sides and screws onto the end of your telescope. The type A is for visual use and I was wondering if it could also be used for taking photographs. To set up you use the shadow method and not your finder scope or an eyepiece as this would cause instant damage to your eye. In effect what I am trying to do is cut costs as these filters are quite expensive here in the UK
