Hi Mark,
Agree, just try it and see and then make changes if needed. Will let you know how I get on.
Yes, will be a Lunt CaK B1200 diagonal.

My First CaK Questions
Ok, here goes. Have read a ton of posts on here (and elsewhere) on this subject but two questions remain:- 1.

Final image is the result of stacking 53 frames in Registax 5.1, touch of wavelets and a little Gimp to finis...

I am a keen amateur astronomer who has been observing the Sun for almost 25 years on and off. Vast majority of that time was spent visually observing and recording sunspot...
