Milton,

I think Alan & Kurt are talking about the non FMT7 800 x 600 pixel size aren`t they?

Yes.

The 814 x 618 pixel image log for my movies had a fps reading I think wheras the log I found for the 800 x 600 pixels one has just an exposure reading of 0.05ms..?

Exposure time has nothing to do with frame rate, except frame rate is the maximum exposure time.

You can be shooting ant 1.75 fps and have the exposure to 0.01 ms (which is 0.00001 or 100,000 th of a second).

Anyway I`ve had a quick look at Fly capture on my PC & it has an "enable" FMT7 selector but the image scale dosen`t seem to change from 800 x 600 pixels on any mode?

Read what we said. It's the 800x600 size that DOES NOT have the words "FMT7" on it. ROI is not enabled for fixed sizes so the only size that you can do is 800x600 in either 8 bit or 16 bit Monochrome with the 2007 and later Scorpions.

This is shooting a blank-no scope but out the door into the light! I don`t know enough about it at this stage! If Alan`s timed it that`s good enough for me..! As to collimation here`s a couple of Jupiter snapshots from last time I shot it, the first at prime focus the other with a 2x barlow & the Scorpion, I believe. I had tried to adjust collimation until I had the clearest view of Jupiter`s stripes through the 25mm eyepiece..

I can`t promise I`ll look at collimation of the scope any time soon (it`s cloudy tonight for instance..!)

You do not use stars for collimation, you use stars! You'll make it worse, not better.

Please READ the URLS I indicated in the previous message because they CLEARLY explain what you should be doing on.

TTYL..
