Quote:Could you shoot a pic of the front / star view of your diagonal and lens based artificial star? And - to be clear, you have a 25mm eyepiece in the middle of the tube, and a 4mm eyepiece at the end? Where do you see the star - some point in front of the 4mm eyepiece?
Quote:That is totally cool. I have spare eyepieces, so will have to give this a shot.I'll post feedback on how it works out...
