I have spent about four days with my new PST and have come up with a couple of questions. Any replies will be greatly appreciated.
1. The PST front objective looks different from any other Coronado example that I have had the pleasure to use. Does the PST have a central obstruction? Is this a new direction for Coronado or is the etalon hidden behind the objective and its dark coating?
2. Why does the 40mm filter (for stacking) cost twice as much as the PST?
I am happily shocked at the quality of the PST and its views. It seems to show more detail than a Helios 1 that has more aperture (70mm).
Also, I would like to comment that the Cemax 12mm eyepiece is noticeably better than my Nagler and Takahashi eyepieces IMO. My TMB eyepieces would not come to focus.
