Re: Difference Between the Orion EON ED80 APO and the Skywatcher ED 80 APO
Bill brings up a very important consideration...weight! I too piggy back a WO ZS 80EDII on my 10" LX200. These scopes are almost identical to what you are considering. I have zero issues with counter balance, but the Losmandy system wasn't cheap either. In your final price, also consider the cost of attachment.
As to your original question, I have not imaged with either scope you have mentioned, but I have looked through them visually. Both are very nice scopes, the fit and finish seems to be the difference. The EON's focuser seemed a little smoother to me, as did the rotator. One caution on using doublets...you have to make sure to focus between filters (even with triplets most people check focus). The color correction is not as precise for imaging. Visually, there are no distracters in either of the scopes you are considering.
I can also attest to the AT-66ED. My friend has one, and it makes great wide fields, but for a guider it may be aperture-limited on your mount. You can see our setups at
By no means am I an expert, but I'm working on it! :) YMMV
Best of luck,

The Orion EON ED 80 and Skywatcher ED 80 are within my price range. They look identical to me and all the descriptions I have seen are the same. I am sure they must both be built by Synta, but am not sure if they are truely identical. The Skywatcher is $100 cheaper. Can anyone say for sure if they are different and if so, in what way.
