mm.. in case you want to know, the pictures were taken using a ETX 90mm RA on the morning of November 4th.

Saturn: Creative webcam using 2x and 3x barlow respectively. About 300 frames each, stacked and processed in Registax2. This is the result straight out of registax. No other modifications.

Moon: Canon ixus 500 through a 27mm eyepiece. Sharpened slightly and noise reduced in Neat. Inset details were taken with the movie mode through a 15mm ep on 3x zoom, and stacked in registax2.

Note tiny crater chain below-right of Ptolemaeus (inset top-right),
Huyginus crater (crater in a rille with collapsed wall; inset middle),
and the alpine valley (inset bottom)

One of the best seen taken locally using ETX90RA.

wow chris, if the etx can do so well...think what your 6" aperture will do!
why not try it and see how the results will turn out?

cheers

Rich,
Haha.. the F5 cannot beat the ETX at high mag unfortunately. Also, there is no tracking.

Thanks guys! Can't wait for Jupiter to rise so that I can try my hand at it again.

Not easy for a f/5 scope to do that rich!

However, if can use a 4x barlow to bring to around f/20 on the webcam, I think it's still worth a try. For tracking, just use your hands to push, Chris. Need a little practice, but can be done if you are viewing that webcam using a small TV. Just be very gentle for say 10 seconds. Since you are using video...it's ok if you can't track it very accurately.
