Well I was thinking the 12" is 22kg Camera is 2kg finder and SBIG remote guider about 1kg = 25kg or 55lbs. On the limit I know.

The mount is totally rock solid you can bash it on the side and not feel it move with the other hand. It's mounted on a massive concrete pier that is at least 1 meter square going down several meters! I used to hold a 22" cassagrain. So there is zero chance of any vibration type issues.

We are surrounded by trees and in a bit of a dip. I can't be bothered imaging anything low down so this doesn't ever cause an issue. Even in howling winds we hardly notice it blowing in the observatory. I currently have a large yellow dew sheild on the front of the 10" so I would have had wind issues by now if I was going to.

So it's just a question of if the mount can track and autoguide well enough with the extra load of a 12". It sure would be nice to have an instrument of this size.
