Yes, I read that review and other info - that's why I'm very interested in this scope. Do you have this scope on a mach1 mount?

I'm the guy who submitted the first-light photo and comments
on the "initial impressions" posting on AstroMart's review
I didn't specify which mount I used, because it is
quite fashionable -- and usually right -- to stress
over-mounting any equipment used for imaging.
But the fact is that, *properly supported*, the Mach1
is just fine. Roland C. seemed to think that this
would be so when I asked him about it, and he was correct.
In fact, the Mach1 is loaded down more heavily than when
I use the TOA-130 on it, and if anything, the tracking
is *better* than with the TOA-130, despite the increased
The CCA-250 is remarkably compact. A lot of its "length"
is really a semi-permanently mounted dew shield in the
front of the scope. But the "working" part of the OTA
is quite short, perhaps 22 inches long or so. I also
use the optional larger shaft with extension on the Mach1,
and two 18-lb counterweights.
I am really thrilled at this combination -- it meets all
of my requirements, and is *truly* eminently portable.
Judge for yourself how effective it is by my little
first-light effort (more to follow when the clouds go
Yes, bigger mounts are better, but the Mach1 handles the
load superbly (I use an OAG, so I don't have a separate
guide scope). Since I must be a mobile imager right now,
and I am not about to carry heavier equipment into the field,
this setup approaches the ideal for me.
I'm sure it will work for you also, providing you will
be imaging in low-wind conditions, and the Mach1 base is
supported in a rock-solid fashion.
Feel free to PM me if you have further questions about the
Mach1/CCA-250 combination, or just post here if that's not

Thanks Herb and Greg,
It looks like we have the same goals: a great imaging platform that is still (just) mobile. I have to schlepp my stuff outside every evening and a few times a year to a star party. I'm using the eagle pier which provides a lot of stability and in my backyard there's usually no wind. Thanks a lot for your info!
... and now I have to find a legitimate reason to convince my wife ... ;-)
