I hope this is the best place to continue discussing PST eye pieces.
My Coronado PST came with the Kelner 20mm (I assume that is what K20 means).
But when I used my Orion Edge-On Planetary 9mm the clarity improved dramatically.
Then I experimented with a polarising filter not expecting much but was even more surprised and pleased to see even more details on the sun disk (at the expense of seeing prominenses). Keep the eye piece in the scope loose and rotate it to the best contrasting view.
Since the 9mm eye piece does 44x magnification, and the PST can go up to 80x or 90x, I want to try and get about 60-70x.
I was hoping to find a 1.5x Barlow lens but these seem rare or non-existent.
My plans are to see if I can piece together a 2x Barlow lens with shorter parts to make an ~1.5x.
Another idea is to try a 1.5x Erecting eye piece.
Any thoughts on if I should try for 60-70x and the cheapest best way to get there?
