Hello,
Could someone tell me what the thread size + pitch of a Coronado BF is please? I have unscrewed the BF
from a Coronado diagonal and want to make an adapter for it.
The thread diameter measures around +/- 33mm.
Thanks,
Pieter

Re: Solar images 150mm pst mod
Pieter, Pretty good results....well done. Just a question - what's the distance/ length of the combined spacers between the etalon and the front of the BF diagonal? The distance between the rear of the pst etalon and the focal plane is about 200mm. This is the value from the original pst scope. The...

Re: One more raw photo for your processing 150mm + 0,2A band
Hi Valery,
There has not been a clear sky here in months, so I tried to process your image.
Hope you like it. I used ImPPG and some Photoshop Actions to boost the contrast.
This is very nice data btw.

Pieter

Re: 295mm D-ERF + C11 scope. SECOND LIGHT. GOOD SEEING!
Hi Valery,
This is very, very impressive. And to think it was the shortest day of the year!
Curious to see how this scope performs when the sun gets higher.

Re: Best donor scope for pst mod?
Thanks for the suggestions, much appreciated! A question to "Merlin66" So if I understand you correctly, the vignetting at the etalon front lens in combination with the 150mm f/8 (fl 1200mm) scope will turn it into an f/10 automatically? That's why no front baffle of 120mm would be needed ...
