Well it finally arrived. And after a quick tweak (as much as the seeing would allow) of the collimation, I quickly put the new C9.25 to work. Jupiter being the first astro target...
Good image scale, crap seeing, but hey not too bad for a first off shot.
~600 frames ToUCam at f/25 (5.9m f/l) C9.25.
Stacked with Registax3.

Normal mode for ToUCAm. None of this Raw mod rubbish!! :)

Cheers

Moon is Europa I think. I think the colour is about right for the moon too.

If that image is from tonight you are right Robby, I had a school viewing night tonight and we watched the Europa shadow transit through a 12" dob. Your image is upside down :P or was it upside down in our the dob? :confused: :D :D

Nice Robby, shame about the seeing.

Shows great promise though, can't wait to see the results on a night of good seeing.

btw how come you got a new OTA?

Long story Mike, well not that long.. Basically ended up in a deal with a Star-Mate with a dealer in the US. I sent him a Star-Mate and he sent me a C9.25 OTA. Almost anyway! I had to send him some cash on the deal. It took awhile to turn up and customs made sure that put all there crubby figers all over it and sucked as much GST as they could from me!
The C8 has done me well, but the longer focal lenght for the C9.25 will be great for astrophotography. Visually it's only a little better than the C8. More contrast if anything else.
Arrived on Wednesday, & I have had two clear nights since then... New gear curse had left me alone this time! Problem is now I need a bigger mount... :)
Cheers

OK, just so us Kiwis stick together, I was on the case at a similar time to Robby. Here's what a 7" scope showed, with similar (4/10) less than ideal seeing
Mewlon 180, 2.5x Powermate. About 630 frames from 700. This is Optimised Colour Mode, a shame Rob is too scared to try something new.

Whats the price difference of a 9.25" and the C8? In Aussie dollars?

Love the 3D effect on the last image. Also the disc of the moon Europa, I only see these as blobs of light through my 8" Dob.
