Looks a lot like this image! (except this is a tad oversharpened on the ridge):

Thanks, Greg. I could play around with warmer temps but I'm going to be away a for a large chunk of winter so I think I'll bite the bullet and see if I can get the camera fixed ASAP. I'll still have data from SRO and New Mexico to process
That field does look quite similar

Seriously though, how have you found the "seeing" in Brisbane over the weekend?? I've been trying to collimate my RC scope and have been getting rather frustrated with poor images...
Do you still have your Tak collimating scope?

Very kind of you, David, but I think the Mach 1 would struggle. How's the big mount going?
I was imaging at 2.4 arcsec/pixel, roughly focused and guiding with a 50mm Borg guide scope, so the seeing could have been 10 arc second and I probably wouldn't have noticed.
I do still have the Tak collimating scope. You're welcome to borrow it if you like.

Thanks, Simon. Last time the camera went back it took ages but that was for a new sensor. Hopefully, they can fix it quickly this time.
Cheers,
Rick.
