Waa waa.

I headed over to John Glossop's place for the weekend out at Cootamundra. Cheers, John, as per always.

This is another paltry image which is far from my best effort. Almost makes me want to quit imaging with a DSLR during summer time. Heat is horrible for noise.

I've also ended up with some horizontal banding which I've never seen before. Incidentally, this was the first time I've used Nebulosity for capture only (straight to the Compact Flash card) and processed in IRIS as per usual. I also used Nebulosity to dither for the first time. I'm not sure if this is the cause of the banding. I hope it's not. This is the first time I've used the software since purchasing it.

I think my camera may have lost focus slightly during the night as well as I don't think I tightened the focus lock tight enough (it was fairly loose this afternoon when I was disassembling my gear).

Anyway, I managed to get 2 hours [5 minute sub-exposures] (4 minutes [24x10 second] and 2 minutes [24x5 second] for the core) right before the Moon's annoying light started to bathe the Cootamundra night sky.

The seeing out at JohnG's place was so good on Saturday night/Sunday morning. Absolutely incredible.

Read and view here.

Comments, criticisms, etc., as always, most welcome. Hit me.
