thinking of getting a Ritchey Chretien

im thinking of getting an 6iinch RC astrograph or the 8 inch Altair Astro GSO 6" F9 Ritchey Chretien Astrograph (Fully Loaded) :: Astrograph telescopes :: Telescopes :: Altair Astro

i really like them and have read that they are good for imaging which is what im after just woundering if any one has one or could recomend something simlar? im just worried about the f ratio of 9 and if i use a reducer would it affect the foucs on the dslr??

I think the point of this scope is to get a long focal length for small targets in a lightweight, easy to mount, quick to cool down package.

I tested the 6" TS version of this R/C and I loved it. Star shapes were excellent and the 'scope itself was a joy to use. I was VERY tempted to buy one for my own use but in the end decided that I would persevere with my old 10" F4.7 Newtonian and refurbished that instead. It was the F9 that made me re-access my requirements as I had narrowband imaging in mind where light capture is a serious consideration.

The long focal length makes it great for Lunar and planetary imaging but smaller objects like galaxies would respond very well too provided you can capture lots of data.

This was the second R/C that I have worked with and I have to say that I like 'em!

thats my aim is to get on galaxys and get lots of data i just fancy a change from the newt as thats all i have ever had so i dont know if i like any other style of scopes

I'm tempted too, it would make a nice alternate to my Orion ED80 which is way too short to capture much in the way of galaxies other than M31 or M33.

Go on get one!!!

got outbid at the last 10secs s.o.b

10 seconds??? A well, there will be more chances! I use an Orion version, see sig, and it is IMHO very good value for money - even new.

Good luck on next auction!

you know what they say: Ritchey Chretiens are for rich cretins. I don't mean that, by the way, it's just a play in words.
