[Chaos-l] t-adapter advice

[Michael Hrivnak]

I picked up a Canon XSi (a DSLR at the top of the "Rebel" line, aka 450D) this 
week, and naturally I want to do some shooting through my refractor.  What do 
I need to know about picking a t-adapter?

I can get a Celestron universal 1.25" t-adapter with Canon ring for $33.

Or, telescopeadapters.com sells a "2" UltraWide Prime Focus Adapter" that 
skips the t-ring and claims to reduce vignetting.  This one is $70.

And advice or other suggestions?

Thanks,
Michael
