Quote:IDK, but Stellarvue makes a 80ED doublet for 499$ for stock focuser and 699 for their 2 speed, they don't say what glass it is, but these are excellent scopes. and of course they have a 110ED doublet also for 995$ or 1295$

Quote:Quote:The celetron onyx fits your bill. Sent you a pm about one. Very true...this is one wonderfule scope. It is so very very hard to coax any CA out of it also, even on brightest objects. It is a surprising performer too, even at highest magnifications. It easily kept pace all the way into planetary magnifications with an 80mm premium triplet super APO I had too. Only oddities about it are that the dew shield sometimes does not stay extended when pointed at the zenith and if you use a 2" diagonal I have come across a few eyepieces that do not come to focus. I eventually sold my $1000+ premium 80 and kept the Onyx and have NEVER looked back
Couldn't agree more. The only reason I am letting mine go is I use my ed100 when I'm home or going local, and I like my 65mm for travel. If I was into astrophotography then it would have a use for me but as it is I don't really use it. I'd like to see it get a home where someone will appreciate it. Mines also custom painted gloss black and blue metallic

Quote:Quote:At f/7.5 (a little longer than you asked for) it will have better color correction than at f/6 and it is FPL-53 as you requested. I knew about this scope but did not realize it had the FPL-53 element. At that price, compromising on focal length could be an option since I could always get the 0.85x reducer/flattener that is (was?) available for these 80mm f/7.5 doublets. But by the time you do that and add in a good focuser you are back up around the price of one of the more deluxe f/6 scopes...there is no free lunch it seems.One issue I have is that I already made an investment in the Orion flattener for short refractors (the one that doesn't change the focal length) in anticipation of finding an f/6 'fractor for AP. Maybe the simple answer is that I just need to be more patient in the used market. One of the SW Equinox came up on Amart last week but I was too slow on the trigger. In fact I was 0-3 on Amart items last week, which was really annoying
Quote:No CA as far as I can tell on the 80MM EON. Never believe anyone that hasn't used the scope talk about it.
