Furious and Pi#@ed Off

[rainwatcher (Peter)]

There is no thread on the crayford focuser to take any of my T ring fittings, it only has the sleeved 1.25 eyepiece hole with the internal locking collet. All of my other adapters are threaded adapters, or in the case of the celestron eyepiece projection mounting it actually fits over the top of the visual back and is held on with 2 screws. I am not trying to extend my focal plane back any further I just need a way of fixing the camera to the 1.25 adapter in the Crayford. Which is why i need something with a 1.25 barrell on one end and a thread on the other that goes into the camera T ring. The CA001 from Andrews or Bintel is just that fitting and is just the trick. $29.

Oh and by the way Paul i am on the lookout for a .63 or .5 FR to speed up the optics.

What type of camera are you using? By the talk of T threads I am assuming it is a DSLR????. If so why not get one of T hread to 2" adaptors,that way you will not bet creating a bottleneck in the imaging train.

Yep, a canon 1000D. Good idea, but i will still be restricted when i use my 1.25 for eyepiece projection. Thanks, i will look into that.

you only have a 1.25" bore in your crayford? It doesn't have a 1.25" - 2" sleeve in it does it? If it does then all you need is one of these http://www.bintel.com.au/Astrophotog...oductview.aspx

[rainwatcher (Peter)]

Yes i misstyped as that idiot H Clinton would say. It is a 2'' bore. Yes i have to get the adapter.

[rainwatcher (Peter)]

Problem solved ! i was too busy being excited to remember the adapter.

I'm still a little baffled, how were you attaching your camera to the telescope with the original focuser? Were you using a tele-extender?

All you should need is a simple T-Ring setup like this:

Is the camera the Canon 1000D?

*EDIT* missed the 2nd page of the thread! Glad to see it is working for you now.
