Ah, really? That's interesting! I would have thought it would be consistent and the target irrelevant. To alleviate me of some of my ignorance, would you mind briefly explaining that?

Edit: Nevermind, reasons are obvious. You stretch them differently depending on the makeup of the nebula which causes different star sizes.

Cracker shots mate! Personally I prefer the stars in the MT version. I think I'll try and get what you've suggested on this one: 3nm for the OIII and 5nm on the SII which I believe will have less of an issue with the moon?
