Can’t go wrong g with OPT or WO

Zenithstar 73 showed up in 2 days and what a piece of equipment it is! Needed one other small piece and it was delivered the same way, so it seems order amount has no bearing on how you’re taken care of. OPT online support was great when needed as well. Definitely on my top list of suppliers moving forward in this astrophotography pursuit.
