Sydney has excellent seeing conditions right now.
This is a most unusual time.
The best I ever saw in Melbourne was 2 arc seconds.
Many nights it was over 7 arc seconds.

Thanks Alan...indeed unusual conditions, but the time I took finally optimising the optical system was also worth the effort.

A new standard there.

Ta Greg, I’ll take that as a very big tick in the box from the man who has a penchant and means for some seriously top-shelf gear.

I actually had no intention of doing “another m42” and it was Marc’s comment about resolving the trapezium that motivated me to point the scope at it in the first place. Looking at the raw data I thought the star profiles looked remarkably tight, it was only then that I decided to stick with it.
