Below is what can be used and seen with the new optical correctors that allows the PST or any other H- Alpha Telescope to be used with a Camera and binoviewer.
These simple plug and play correctors are all you need to have comfortable 2 eye viewing with your TV, AP, Denk, BN, Burgess, SV, WO, Celestron, Orion and most other binoviewers you can think of.
This Photo taken with a PST and a Black night binoviewer using a 19mm Ultra. Camera hand held.
These optical correctors can be use with any Binoviewer
in any H-Alpha telescope. Some thought that the PST could never use a binoviewer because of its limitations, but this is no longer the case. Shown
here is the 1.5x
corrector that has been discontinued in favor of the 1.3x corrector..
