Dave,
I've been thinking about your setup a bit.
There is no doubt that your Canon lens' are doing the job- sharp, excellent contrast and color. But they are pretty low power which limits their use for wildlife.

I wonder if you considered adapting that Orion 80m Ed for wildlife photography? I would think it would give good results. All you would need is a T ring and an extension tube for under 50 bucks and you would be in business.

If it's the scope I'm thinking of it would give you 18x at f7.5 setup for prime focus- plenty good enough for most situations and then you wouldn't be so limited to just feeder birds. A 600mm tele for 50 bucks is a good deal.

Just a thought.

Thanks Sparrow, i have the t-ring and i believe i have
an extension tube that might work.
Right now my biggest problem is a tripod to mount that
scope on, i just have a cheesy tripod, it works ok for
just the 20D and the lenses i have but the scope/20D
combo is too much for it, tough to balance and just breathing on it causes it to bounce around.
Recommend any descent tripods that would work ?
I did try the ED80 a time or two last year, the camera was just mounted with a t-ring, the closest i could get focus was on something atleast 75ft away.
Here`s a couple shots taken with it...

First of all your Hummer pic is first rate. You can't get much better than that.

Tele stuff:
Tripod-I use a Bogen tripod 3228+3047 head+ 3273 Pro quick release
assembly on the short tube. The quick release should solve your balance
problem pretty much. See pic of this setup.

The only thing better is the Bogen 3421 Gimbal fork mount which would
give you perfect balance but it's expensive and large and needs a pretty
robust tripod to work really well. I use this set up with a Bogen 3246
tripod for the 100mm Pentax. It's a large heavy setup but at 40x nothing
else will really do.

Your focus problem should be solved with an extension tube. You need
about a 80mm extension tube to replace the focal length lost by removing
the diagonal. This should bring focus much closer.

Sparrow,

I think this bird is a Lincoln's Sparrow, not a Song Sparrow. Song sparrows have a black "stickpin" in the center of their chests. Lincoln's Sparrows have this buffy necklace
