Easy upgrade for your scope
This lens is amazing, it opens up many astrophotography possibilities for the Nexstar and Evolution Alt-Azimuth mounted Schmidt-Cassegrain telescope. Essentially turning your f/10 telescope into a f/6.3, reducing exposure times to within acceptable limits (on some deep sky objects), I highly recommend this lens.

Dr. Katz is hilarious
I have always loved Dr. Katz, so funny, many gifted comedians including Jonathan Katz himself!
