I'm a bit late to the party, as I went out west to do some dark sky Astronomy. So when I got home I hastily set up my ED72 with my Combo Quark to catch this great prom.
I still haven't eliminated the Telecentric Barlow reflections when imaging proms, any suggestions for fixing this would be most appreciated.
I'm thinking of getting a TZ4, but I'm not sure if this Barlow is free from reflections.
