Which scope to buy

I have enough money to buy either a CPC 800 Deluxe HD or CPC 1100 XLT. The question is do I sacrifice 3 inches of aperture for a better quality optical system?
I will be using the scope mainly for observation but also some solar system imaging.
Any advice would be appreciated

The biggest differences between your two choices are:

- much brighter views of deep space objects in the 11"

- 65 pounds fork/ota weight of the 11" vs 42 pounds for the 8"

- smaller OTA size and vents in the 8" allow better cooling and stability for high power views of planets (can add tempest cooling fans).

The outer part of the field of view is much better in the 8" due to the built in field flattener but that's a less important issue than the first three I think.

Another option would be to buy the C11 from the classifieds and put it on an equatorial mount - then you could use more than one OTA. Buying second hand means you don't lose a fortune at resale if you change your mind.

are you moving it around much?, C11 starts to get into the heavy territory whereas a C8 is easily manageable in comparison
permanent -c11
portable C8

i agree with tony the C11 in the classifieds is a steal
