I have a baader varilock. It connects to DSLR with a camera t adapter - but how do you attach to a dedicated astronomy camera like a zwo?
Setup: corrector - flattened t-adapter - varilock - camera/Nikon t-adapter
Now I want to use zwo camera. Need connector or something.
Also: Can I connect a Clicklock to the varilock?

Thank you for answering my previous question but I am new at astrophotography and I’d like to ask how does the clicklock attach to the varilock. Does it use set screws or does it thread on? If so exactly how does it connect or do I need something aditional to connect the part of the varilock that twist out to adjust with measurement on it screws to a t adapter the other end is where I want to attach clicklock .

Good afternoon. I've a Ziel Newton 150/750 mm + Canon EOS 1100D + Protective T ring. The focuser is near the end with this setup. When I add also the coma corrector (MPCC), I can't reach focus because it's too inside. Could this product help me? I have also to buy other parts?

Perfect for the job
I bought the 29-46 T2 extension tube to allow me to get the correct spacing between the Optec Lepus 0.62 standard edition reducer and the Optec Adapter T2/Lepus. For the Canon EOS I needed 35mm extension so this fitted the role perfectly. Further it also allows me to use it with the Nikon DSLR by increasing the spacing appropriately.

It was very easy to set up and very sturdy/rigid once the locking ring was tightened.
  • Very well engineered, lightweight, flexible in use, physically rigid and very easy to set-up.
  • A bit expensive, but actually cheaper than the alternatives, especially when operating both Canon and Nikon DSLRs.
