Question C11, question

I just obtained C11 (from garymck, thank you!).
I have a question, would this adapter be OK for Canon EOS?
I have T (M42x0.75mm -> EOS adapter

That's the same adapter I have for my SCT plus my Canon t-ring.

Yes, the t ring will screw onto the t thread at the end of the SCT adapter.
There should be an adapter on the C11 rear cell which goes from 3.25" to 2"SCT thread.

Another question....
Is this any good for C11 weight?
or this?
I may also need a suitable puck (for EQ6... I have one, not sure yet if it will fit the adapter)

Bojan,
I use the C11 (with many add-ons) on the NEQ6 mount.

What dovetail is currently fitted to the OTA - the narrow Vixen type or the wider Losmandy type?

I use a dual saddle on the NEQ6 which will accept either, but feel the Losmandy gives more rigidity.

Hi Ken,
It is Losmandy (on both sides - so I have one extra on top), and it definitelly looks stronger than Vixen

Bojan,
Just check your NEQ6 saddle...the newer designs included a basic Vixen/ Losmandy capability.

The other adaptors - what did you have in mind???? Mounting cameras/ guiders etc on the top rail?

(I use an ADM mini-rail on the top of my C11 to hold the electronic guider and support for the spectroscope)

I have older, classic EQ6 saddle, for Vixen style bar.. so I need to change it with Losmandy saddle..

Something like this (but not for US$120....).

Yeah,
I have the dual Vixen/Losmandy version of this. I have the Geoptic version on the NEQ6 and the Losmandy version on the HEQ5.
Certainly quality product, and works 100%

ADM prices are reasonable for the good quality. You can buy the Skywatcher dual saddle cheaper but it's not very good; the dovetail bar doesn't sit square in the Skywatcher.

Still... I think I can machine it for much less than that. It's only aluminium after all.... plus couple of M8 screws and knobs.
What I want is functionality, not looks.

Fair enough..... I'd make the stuff too if I could

I have a pedestal drill for repurposing existing plates or saddles. One thing I don't enjoy is cleaning up metal waste.

Here (on CN forum) you can find drawings of Losmandy bar...
Might be useful for someone.

Bojan,
This x0.63 corrector has been around for many years and widely used.
Getting the correct back focus distance (105mm) is important for performance.

Not the best in class, but seems capable. What camera will you be using?
