introduce minute vibrations that reduce CCD resolution.

I have a CM1400 and use it for CCD work with the ST7E camera. I
originally used it with the CI700 mount that was part of the original
sales package. I was always disappointed with the results. I
understand the CI700 is similiar to the G11, but perhaps not as good.
I finally lucked out and found an AP1200GTO mount and life has been
wonderful since.

Here is a CCD benchmark between the CI700 and the AP1200:

AP1200GTO picture:


ebula+30May2001.jpg&.src=ph&.view=t&.hires=t


Both images were made using the CM1400 and the ST7E running at the
F/11 focal ratio. The CI700 shot had minimal mass in the system,
while the AP1200GTO shot had a TV101 piggybacked atop the CM1400.

The mount made all the difference in the world. The CI700 shot was
the best I ever got with it. I sold it to a visual-only fellow that
is quite happy with it.

Beautiful shot! I have a AP1200GTO scheduled for delivery in January
because of my frustration with trying to do CCD with the C14-G11
combo. Hope I have as much sucess as you have...Ken

Thanks for the comment on the shot. I think you will have equally
good or better shots once you get that prized AP1200GTO.

That mount is fantastic. I just love it. I finally have a platform
that I can mount nearly anything. Lately I have been running a pair
of refractors in tandem: an FSQ106 for imaging and a TV101 as the
finderscope. You will really enjoy your mount.
