Quote:Hi Bob:I have not migrated from a C11 to an 8SE, but I can probably offer some perspective. I've looked through a 12" dob and found the views better than the 8, but not hugely so. You will definitely notice some reduction in what you can see, but I think you'll be pretty happy with the tradeoff for portability - HUGE difference there!The thing you will likely notice most is that the 8SE will be considerably more shaky than the CPC. Again, this is a tradeoff for portability. The tripod is lighter and so is the mount. The problem can be mitigated to some degree by using anti-vibration pads (about a 50% reduction in settling time) and by hanging a weight (e.g. powertank) from the spreader. Some also purchase a motorized focuser to eliminate the need to touch the scope, which removes that as a source for vibrations.But in the end, it will never be as stable as the CPC. In fact, some SE owners upgrade their tripod to the CPC tripod to gain some stability. For my 2 cents, that defeats the purpose of owning the SE by adding weight and bulk. If you think this may be an issue for you, you may want to see if you can find a nearby owner or astro shop and try one out.-Dan

Quote:Using the CPC mount has been the best addition to my c8se. The whole set up is much more stable and less toy like. As for portability...it's mow a two piece set up as opposed to a one piece. For outings it really doesn't matter, it was always a two piece set up. If you can find one of these used for around 150.00, don't pass it up.

Quote:The takeaway I am coming away with is to keep my CPC1100 and buy a used 8SE. I can probably get a used one for $750. The only thing I would want to upgrade is to a 2" diagonal. I am concerned with vibration in the wind. The cpc1100 is like a tank...but the 8Se is my grab and go.
