Richey-Chretien Astrographs
Hi
I notice that Lee Andrew has Richey-Chretien astrographs at very attractive prices. I am considering getting an RC-8in f8 for use with my DSI2 and Canon 400D imaging cameras. However, I would like some advice from those who have had experience with this type of scope, especially:
1. Would the above scope be suitable for use with my guiding cameras?
2. I understand that there are some issues with the focuser and focuser travel with R-C scopes - if so what are they?
3. Could focal reducers be used with an R-C (focuser travel?)
4. How does the weight of an R-C compare with a comparable Schmidt-Cassegrain scopes?
5. Any other comments?
Cheers Peter
