The really lousy weather around Toronto has made me satisfy my addiction by turning to astro themed projects.  I recently performed a PST mod by placing the PST body and etalon into a larger f/10 scope.  This was you benefit from the much larger resolving aperture vs the original 40mm aperture of the PST.  Here's an initial image:

This is what the modded PST looks like:

The next step is to remove the etalon and BF5 filter from the PST body and installed them into the optical train with some adaptors and diagonal.  The PST has a really lousy prism that degrades the image.
