Hello all. I keep vacillating between the Celestron C6 SCT on the AVX mount vs the Orion ED80 on the Sirius EQ-G.

My main concern is the mounts - I don't know which is better, or why Orion's is more expensive with basically the same specs.

The telescopes... I can't decide on whether I want to deal with the frustration of imaging through an SCT or the frustration of dealing with the errors in a doublet refractor.

Finally, add on question: does the Canon T3i have the mojo for good astro imaging?

Thank you!
