PST improvemnts
Suzy_A,
The Kellner that comes with the PST, I agree is pretty basic! I'm sure you have a better 10mm in your box.
To get focus on a webcam I had to unscrew the eyepiece holder and remove the bottom spacer, then re-mount the eyepiece tube (it has the BF at the bottom).
If you are going to use the PST etalon on a 80mm scope, PLEASE make sure you also fit an effective ERF filter up front!!
