Good to know, I didn't realise Antares was a double star too. I might try to split it one of these days, to test out how good my collimation is
I ended up collimating on Hadar (which was high up on the horizon). If you have any other suggested targets to test my collimation, pls let me know.

Miaplacidus (beta Car) in the south is probably a good choice.
