Congrats Jen, hope you have a ball with it.
Hmmm getting focus with PST and a camera can be a bit of a pita at times. My experience is that the chip is too far away and you will need a shorter 1.25" adapter. Either that or screw an old barlow lens (sans the barlow tube) onto the end of the adapter. You'll get a bit of magnification but you should be able to reach focus that way ..... if the chip isn't tooooooo far away.
What would be realllllly nice on the pst is if the eyepiece holder could screw off and you could screw the camera directly to the pst. Would work a treat then.
