Dirt cheap PST mod pic


Recommended Posts

Just for fun, I modded a little Celestron Powerseeker 70mm f.10 scope I had knocking about. I don't use it for anything due to the terrible plastic focuser and awful distortion around the edges, but its f.10 so i thought what the heck. I threw out the focuser and made up an adapter out of old plastic pipe to hold a 2" extender. I pushed this into the scope tube and set it to hold the etalon at -200mm inside focus. Taped an ERF on the front of the hood and stuck the pst in the back end. I didn't bother to collimate it as I just wanted to see how it worked. The whole mod process only took just over an hour.

Anyway, here is the first light pic. Yes it is upside down.
