T-Ring adapter / Spacer?

Hi Guys

I bought a 40mm slide Adapter + T-ring a few weeks ago, I've only just had the time and chance to use it, when i use the T-ring and camera i run out of thread on the scopes focuser just before it comes into focus.

I was wondering if there was another adapter that i would need to help bring it into focus, prior to getting to the end of the tread?

The scope I'm using is a Bushnell 4.5" (150mm) x 900mm


Cheers

Shannon

I had a similar problem and I bought a 50mm extention tube. You might need a longer one...? (I know there was an 80mm when I got mine).
Mine is basically the same as this:

I think you would want this one: http://www.bintel.com.au/Accessories...oductview.aspx

I don't think the one suggested will fit into your telescope. From the looks of it you can only use 1.25" accessories in the focuser.
There are 2 that might do the job:

or

The second one will add 50mm and should do the trick.
