Guys how would this connect to the camera please?

Without the field flattener i have:

Focuser--Extender--T-Adapter-T-Ring-DSLR

With the flattener how will this work please? And does the flattener have any effect on the exposures?

Thanks, Steve

You need this http://www.firstlightoptics.com/adaptors/skywatcher-dslr-m48-ring-adapter.html to connect it to the camera, then you may need this http://www.firstlightoptics.com/adaptors/flo-adapter-for-skywatcher-focal-reducers.html on the other end if it's going directly into a 2" focuser. If you have the stock focuser on your ED80, then it screws directly into that.

Yes it's a flattener / reducer, so will reduce your focal length my 0.85x and the spedd of your scope by the same 0.85x.

Thanks for that. I already have a T ring for my 1100d though.. Why do I need that T48 one? I have the stock ED80 Skywatcher focuser so not sure what the adapter does?

The standard T-ring is M42 I think , the back of the F/F is M48 and the Canon M48 T-ring adaptor screws directly onto the back of the F/F.
