Thanks Dave! Yes – I used the DMK31AF04 that I purchased at the Qld Astrofest from those nice people at Bintel. The pixels are 4.65microns compared to the 5.6micron pixels of the DMK21, so in theory, the resolution should be better?
Although the DMK31 can only record at a max of 30fps compared to the 60fps of the DMK21, a big advantage is the 1024x768 chip compared to the 640x480 of the DMK21. Getting a star on the chip at an effective focal length of 8720mm at F48 is sure easier with the DMK31 after a GoTo.
My experience from my last efforts helped me decide on more optimum settings for the split, as I think the seeing and altitude were similar. Using the x4 PowerMate also helped separate the Pup further from the glare of Sirius A.
Cheers
