Not sure Thredbo would be any good as its pretty windy there.
But yeah a trip to my dark site could be an interesting exercise.

I cant put my finger on it exactly, perhaps the exposure time, I did 10hrs lum, that might be the diff.

Did you process much in PS?, was focus OK?.
It was taken over 2 nights. I am not exactly sure what the seeing is like but generally speaking the seeing at my home is not as good as the seeing at my dark site which tends to be quite good.

Red subs seemed a bit bloated but luminance seems OK.
Extra time always goes down well.

I am happy with it as is. I am sure a better version could be made as with any image.

A trip to my dark site with a tripod for the PME would be interesting.

I'll also have to check collimation as I haven't collimated it since I got it as CCD inspector said it was close. I should really tweak it though.

Most images of this object aren't particularly sharp or lack colour.
It could always be improved. I noticed the red subs were fat so perhaps temperatures shifted and a refocus was needed. Still I think it turned out well. As I said above luminance is pretty sharp.

Am I imagining it or were your early shots with the 17" a bit sharper? I am imagining it is a seeing issue...hell I know about that

Never the less still a cool easy grab of a cool looking object.
