Hello
Here are some Moonscapes from the Tak Mewlon 180 F12 taken at prime focus. The jet stream has been dominant, hovering over Brisbane the last week or so making the seeing conditions quite poor; the image would not stand up to a Barlow or PowerMate.
The 1200 frame avi’s were processed in Registax 4 with the final stacks ranging from 29 to 375 frames, showing how variable the seeing was. I let R4 choose the alignment points and the choices ranged from 17 to 32! Boy, did R4 take a loooong time to chug through those avi’s!
Those nice people from Bintel came up to the Qld Astrofest with a DMK31AF04.AS (Firewire) at a fire sale price, so I just had to take it off their hands to save Mike carrying it back to the Sydney shop! It was simply fabulous to be able to capture at the 1024x768 size of the DMK31 compared to the postage stamp sized 640x480 DMK.
It is worth noting that despite the poor seeing, the small craterlets in Plato are still resolved at the prime focus of the ‘scope, something which really surprised me.
Cheers
Dennis
