Wispy!

I notice you've shot this at f5 on the FSQ - I'm assuming that means native focal length without a reducer / flattener. Out of curiosity, how flat was the field before you removed the stars? We have a 16803 and FSQ in the school observatory, but haven't tried that combination together so far.

Thanks,
DT
