Conecting 1100D, T-Ring and ED-80

[ubertank]

I'm thinking this is another stupid question from me - most of mine are..however I'm struggling to see how I can connect my 1100D with the T-ring to the ED80.

I can't see how to connect it either to the diagonal, or directly onto the scope. The T-Ring is the 1100D AF one ordered from FLO.

Anyone able to offer up some advice?

Looking at it, I think the issue is that the ED80 comes with a diagonal that is 2", but has a 1.25" adaptor for it. The 1.25 doesn't have any sort of thread for the T-Ring to screw onto though. I presume this is where my issue lies or am I just being massively daft?

So with it looking like I have the wrong T-ring from FLO, can anyone point me in the direction of the correct one please ?

You also need a t-adapter, which slots into the focuser the same way an eyepiece would, leaving a thread exposed for the t-ring to screw onto.

[ubertank]

Yeah. I had a feeling it would be something daft.

Thanks for the reply.

never used an 80 ed but I was under the impression that the camera connects without the diagonal.

other option might be to use a 2x barlow, mine has the T thread on it, If you dont want the magnification, unscrew the lens and just use the tube.

assuming you have a 1.23" Barlow!!

[Radar2312]

1.25", even, D'oh!!!!

I have never used or had a ED80, but would think a extension tube will be required if the Diagonal in not used (1 less bit of glass) and this would fit on to the adapter ring that goes in to the T-Ring....something like this image,,,Camera, T-Ring then the adapter ring that has a thread to go in the T-Ring and a should to take a extension.....

Extensions come in all shapes and sizes.......

You sir, have saved my last clear sky for the next week. If I ever meet you, I will buy you a beer.

In fact you live in Sutton Coldfield..so do I

[Radar2312]

now that may just be what you call a 'happy coincidence'

Im actually in Streetly, but use Sutton Coldfield as opposed to Walsall!! :-)

And when you get the Field flattener for the ED80 ( recommended ) you'll need an M48 adaptor to screw the camera directly to it . . . http://www.opticalvi..._t-ring_adaptor
