Hi everyone,

I had decent seeing this morning, but not as good as I hoped for.

Meade LX90 8" SCT @ f/60, ToUcam 840 w/IR block filter, Seeing 5-6/10, stack of 375/1811 @ 10fps.

Thanks,
Ed Roach

What a great image Ed, I like it very much

f/60 that's alot of magnification. Can you explain how do you reach that sum? If this image is 1 to 1 I have to calculate my magnification again it is a little smaller and thought at f/45

Hi Ed,

Very nice image, thanks for posting.

Very nice shot Ed. Your caught the North Polar Hood clearly, as well as the Gomer Sinus "fork" features.

Best Wishes

Hi Ed -

That's a very fine result! Interesting to note the number of frames you selected - would you say this is a normal ratio of good/rejected frames from your location? I can almost define the seeing conditions by the percentage of usable frames from my location - 20-25% is my average for 5-6/10

Thanks Robert your comments are appreciated.
I placed my Meade #140 2x barlow into my diagonal, placed my 2.5x Powermate into the Meade and put the Toucam into the Powermate.
Before I checked the focal ratio in K3CCD Tools I figured I'd get to about f/50 to f/52 with that combo, but it brought me to f/60. Maybe it had to do with the primary mirror being closer towards the rear cell to get into focus creating the longer focal length/ratio?

Thanks everyone for the nice comments, they are greatly appreciated.
