Thank you so much guys Am now thinking of a sky watcher 80ED and a HEQ5 as I feel an EQ6 may be a bit too expensive With regards to collimation, how often must it be done on a refractor?

WOW guys thanks for the fast feedback! Yes I was unsure if the astrograph would be a good idea and am now looking more at a refactor. You say 80ED, is this some sort of standard? Also i was thinking of maybe a used advanced vx from celestron, would this and an 80ed be good for astrophotography (specifically nebulae)? http://www.astrobuysell.com/uk/propview.php?view=108096 also, are there any recommended 80eds?

Hey guys, I was thinking of purchasing a telescope, primarily for astrophotography. I as unsure as to what kind of telescope I should get. I have heard good thing about the Orion astrographs (8" http://uk.telescope.com/Orion-8-f39-Newtonian-Astrograph-Reflector-Telescope/p/109883.uts?keyword=astrograph 10"http://uk.telescope.com/Telescopes/Reflector-Telescopes/Reflector-Optical-Tube-Assemblies/Orion-10-f39-Newtonian-Astrograph-Reflector-Telescope/pc/1306/c/1315/sc/1350/p/109882.uts) but do not know if it would be better to get something like these or a refactor (preferably APO). Mount - wise, I will most likely purchase used (if that is recommended) but am unsure of exactly what would be recommended for these wider telescopes. Sorry for any "rookie" errors, as I am new here All help appreciated!
