Sorry for my ignorance?
What type (reflector or refractor) is a C6 Celestron/Vixen 6" f/5.
For what it is worth. I compared my 1250 fl 10" to Ken's 1500 fl 12" and saturn was 10 - 15% bigger and clearer. This is only a rough guide.
I also look thru a 6" reflector at eta carina and my 10" blew it away.
The 8" is 1250 fl from memory, so magnification will be similiar to the 10" if i am correct???
I would go the 8", you can always sell it 2nd hand in a years time for close to what you pay now if it is in good nick!
