I have one and I am sad to say I don¡¯t love it.
When it works, it's incredible.
It's dependent on an internal GPS chip and it takes .....fooooorever to lock on a signal.?
Which defeats the purpose of maximizing my observing time.? Currently on loan to one of my SAS members to try before buying.
I think astrohopper does as well as a job and it's free.
