Hi All,
Am a newbie, and this is my first post, so please be gentle
I have a question which I hope you awesome ppls can answer for me?
Hopefully I can ask it correctly.
I currently own a Celestron C10-NGT complete kit theses are it specs
http://yorkoptical.com.au/ProductMen...ee3%2cUnitCost, I will be using it with my unmodded Eos 40d.
Basically my question is, the current finderscope is okay, however I wish to upgrade and put something else in it's place and I was looking at the Orion ShortTube 80 refractor kit, with StarShoot AutoGuider, & 1.25" Extension tube (for focus) it's specs as follows

What sort of issues would I get in using it for Astrophotography, bearing in mind that the Celestron is F4.5 reflecter & the Orion is F5 refractor.
I heard/read somewhare that the two scopes would be fighting against each other in speed/focussing? Not to sure . . .
