This might be a dumb question, but are blocking/ITF filters the same in the Solarmax 1 and Solarmax 2 scopes? If I bought a new BF10 would it be safe in the older Solarmax 60? The blocking filter that I have looks good, but when I unscrew it (eyepiece side) and shine a light into the diagonal housing, I see some clouding on the backside of the ITF filter. However, the ITF filter still has a nice reflective coating when viewing it from the outside (telescope side of the diagonal). Is it safe to use in that condition? I know it's possible to change out the ITF, but I'm considering buying a brand new BF10 filter/ITF/diagonal, and then getting an upgraded ITF for the old BF10 unit a little later. In the interim, I've placed a Baader UV/IR Cut/L-Filter in the nosepiece of the diagonal in front of the ITF filter.
Thanks for any advice, I really appreciate it!
