Re: Dovetail size for CEM60
If the telescope has the factory dovetail and rings on it you may find that the tension knobs for the rings will not fit onto the mount.
If you purchase a longer dovetail bar you can either attach the old bar to the new one or purchase new tube rings.

I am attaching 2 images, one highlighting the problem and the second is the underside of the vixen dovetail on the telescope.

Re: Dovetail size for CEM60
Teleskop-Service sells many 300mm Vixen style dovetail plates, I prefer to use solid bars instead of extruded but the cost is higher for those.
With the weight of the 105mm a extruded bar will work fine though.
https://www.teleskop-express.de/en/moun ... l-bars-308
They are also available from Astroshop: https://www.astroshop.eu/mountings-acce ... Prism+rail
APM Teleskope sells 300mm plates as well: https://www.apm-telescopes.net/en/geopt ... nght-330mm
Bresser is the Europe distributor of Vixen so you may want to call/ email them and see if they have anything in stock.
You will have to purchase a new set of tube clamps/ rings though and all three of these sites sell them as well.
Enjoy the Vixen, I love my SD115s and unfortunately I had to pass along a A105M II at the beginning of the month.
Wonderful refractors.

Re: Dovetail size for CEM60
After a further consultation with my local astronomy equipment store, I bought this Vixen plate https://www.optiqueperret.ch/acs-vixen/ ... bar-m.html.
It worked well, replaced the original Vixen dovetail plate and installed this new one. It also had bolts to replace the large clamping bolts.
The telescope now snuggly sits in the CEM mount. I am attaching two photos.

Re: Dovetail size for CEM60
I removed the handle and bolted the plate to the top of the rings.
This way I could mount it on the Vixen or Celestron mount just by flipping the tube.
