Thanks Ricochet that's the answer. I'm trying to do this without spending anymore money except on the dob mount🙁 Quick follow up question is there much difference between Omegon Mount Dobsonian mini base and the Omegon Mini II Dobsonian mount apart from the extra £10?

There is no dovetail on the bit behind the bar in the picture, which might imply it's not meant to be fitted directly. Does that mean I need to get get a piece of dovetailed metal to attach to the OTA which then is clamped by the (pictured above) dob mount?

I wonder if that bar has been added so it attaches to the (non-original) mount. If I removed it would it then attach to this?

27mm in the center and 34mm at the edges.

I have a konus motormax 90 which is a Maksutov-Cassegrain type telescope. I got it for £25 at a car boot sale but I don't think the mount is the original one. It is virtually impossible to use, I tried converting it from eq to alt-az which helps a little. The main problem is it vibrates so much, focussing is next to impossible even at low magnification. I got a little dob from ebay - 300mm FL. This is rock steady and great for what it is but the lack of magnification is limiting. What I want to know is: Can I convert the konus motormax 90 to a dob mount with something like the Omegon Mount Dobsonian mini base with synta dovetail? The attachment point on the konus motormax 90 for the mount appears to be non-standard (very thin) do you agree. Thanks in advance.
