Lens mounting options

[Phillyo]

I've been scouring the net to find the best way to connect my camera and lens to my astrotrac but I'm a bit stumped.

I have the ZWO ASI533 arriving in a couple of days along with the Samyang 135mm lens. I use an astrotrac with the 410 Junior Geared Head and a ball head on top to the camera (Currently a Sony a9). I'm looking for some 70mm rings that I can connect to a doveplate I'm assuming? Or if I buy the ZWO camera mount will that be strong enough to hold the lens without flexion in the imaging train? 

Any advice greatly appreciated!

If the ZWO fits then I’d get one of these:

Hi jambouk, 

Thanks for your reply. If I use this style of connection will I still be able to use my 2" uv/ir filter?

According to the long running "imaging with a Samyang" thread this fits the 135mm f/2 lens.

The adapter is mentioned from page 11 on.
