Hi Fellows!

 

Hope that all is well!

 

 

I just bought another scope that I am going to use for in some distant future as a solar scope. Just starting.

 

1. Do I need Energy Rejection Filter at all? or the objective can keep up without it? it is 6'' achromatic. My intention is imaging only. No observations.  I know that Energy rejection filters are quite expensive, so I decided to double check with the community :) surely I will add narrow band later in the optical train.

 

2. if I do need Energy rejection filter - what is the best place for it?  to cap it on dew shield or directly the objective lens?

 

thank you!

 

Best,

Andrey

Very same question I asked when I first started solar imaging. See here. Pictures are very helpful courtesy of solar guru Marty Wise
