I noticed that the max payload capacity of the porta-mount is listed at 10 lbs. My C6 OTA with accessories is pretty close to 10 lbs. Would the Porta be sufficient for this scope? How much vibration could I expect while focusing and slewing?

shams42,
I have my Brandon 94 mounted on mine it is Close to 14 lbs and works fine,I have seen the weight range listed by many dealers as 10-20 lbs maximum load which I think is over estimated. It appears that shorter tubes do allow you mount a slightly heavier telescope. I have had the power to 180X vibration is not much of a problem Though I do use a set of Celestron Anti-vibration pads. If you do get this mount be sure to get Longer flexiable cables they definately make life easier. The most critical thing is balance when using this mount, Only adjust the tension to hold the scope, fine tune the balance by sliding the tube along the dovetail bracket.

Yes, absolutely enough, and not much jitter at all.

I just ordered a Porta Mount. I believe there's 2 varieties now. I believe the larger has 20lbs payload

I own a Porta and it will easily support the C6 with very little vibration. In fact, I also had mounted on it a Meade 8" classic SCT that weighed about 16 pounds with diagonal/finder scope and it also worked great with not much vibrational dampening time. Very good mount for the money.

I've used my Orion 150mm Mak on my Vixen Porta, no problem. I highly recommend you upgrade the Vixen Porta with a Manny'sâ„¢ Panhandle and the longer Antares control cables ($10 at Agena Astro):

With a long focal length scope and a high magnification eyepiece, keeping things in view is a little trickier than with a GEM.

I didn't know they were steady at the bigger payloads. Just made my mind up to get one. Thanks.
