Re: Solarmax 40 and Baader H Alpha 35mm CCD filter
You mean you expect replacing the itf (and not erf) from the diagonal with this ha filter?
Visually it is dangerous!
Even if baader 35nm is similar to the erf that are not blocking ir as good as itf!
If itf is rusted then ask m’aider or beloptik for replacement!

Re: Binoviewing Lunt 40
I’m using a celestron ultima barlow and a small extension to reach the focus
Is your problem intra or extra focal?
Do you need to place your bino inside or outside to teach focus?

sweet spot and f/d effect
hello just a quick question : presuming I modify a lunt 50 f:d 7 presure tuner, how will f/d scope impact the sweet spot? to be clear, what do you think about using a 127mm mak with f:11 or f/15 ratio vs my current 130 f/7 scope? I assume that Bandwidth would be positively impacted, but sweet spot???
