Hi Wes,

It wouldn't be less sensitive, but I'm wondering about gain levels at the 15-30 fps range, particularly when using a smaller scope. This is where my uncertainty lies.... if the same ICX098BL is used at 15 and 30 fps, say, will the gain have to be increased so much on dimmer targets that it outweighs the benefits of no compression? With the standard Toucam which has the color version of the 098, I've seen a significant dimming when going to even 10 fps on a target like Saturn which requires a gain increase of about 70% or so. I know the monochrome version wouldn't have this much increase, but there would still be a jump.

Oh, I think with a scope like yours, you'll benefit greatly from these faster cameras because you have more than enough aperture to compensate, but unless a CCD significantly more sensitive and/or less noisy is used, the smaller scopes are going to have a harder time benefiting from the additional frames... unless a bright target like the moon, sun or maybe Jupiter is imaged.

I predict you'll have good results with the camera you have coming and look forward to seeing the images! (Is that the one with the 424/204 CCD?) You certainly have the aperture and conditions to benefit from these faster cameras.

Here's my latest image of Jupiter. Seeing was good but contrast isn't that great because of the Moon close by. Note the "small red SEB spot". Note the huge blue Festoon at the EB and the dark barge on top of the STB spot!

The oval BA is also rising on the right.
