In my arsenal, it's my Stellarvue SV80T apo, FPL-53 version. But followed very, very closely by my SV85S with the LOMO doublet.

Well, I have an SV80S that I love. The LOMO optics are excellent as is the Feathertouch focuser. Best 80mm scope, though? I don't know. That depends on the criteria you use. While my SV80S is wonderful, the focuser is non-rotatable (which some may object to), the entire package is fairly heavy given the aperture, the field is heavily curved due to the relatively short focal length, high power eyepieces that are comfortable to use can be expensive (again due to the short focal length), and the scope is not inexpensive.
What criteria should we use use when assessing "best"? Optically best? Mechanically? Best support? Best price/performance ratio? Lightest/most easily transported? Fastest cooling? Most robust? Flattest field? Best planetary performance? Best imaging scope?

Well out the 80mm scopes that I've had:
Orion ST80 f/5 achro
large amounts of falsse color, quite distracting. Could not go to very high powers on double stars without noticing significant aberrations in image. Not really usable at 150x. Light weight focuser. Was one of my first scopes and was a good beginner scope.
Stellerview AT1010 78mm f/6.15 achro
still significant false color, somewhat distracting, but much better than the ST80. Could not go to very high powers on double stars without noticing significant aberrations in image. Astigmatism and coma? present, prevented achieving maximum resolution. Maximum use at about 150x. Nice 2" focuser, smooth. Good low power widefield scope.
William Optic Megrez 80 SD II Semi-Apochromatic f/6.2
still some moderate false color, but much better than both the ST80 and the AT1010. Stars pinpoint. very little other detrimental aberration seen. Could go to very high powers on double stars and planets without noticing significant aberrations in image. Maximum use at about 200x-220x. Excellent resolution, very good contrast. Nice rotatable 2" (but only single speed) focuser, very smooth.
TMB 80 Signature Series Carbon Fiber Apochromat f/6.2
No false color. Stars very fine pinpoints. No noticable aberrations seen. Resolution excellent. Contrast excellent. Have seen mag 13.05 star next to M57 under mag 5.5 sky, best ever with any scope smaller than 100mm. Could go to very high powers on double stars and planets. Have used 250x on doubles. Viewed Saturn at 200x, although better at 150x-160x. Nice 2" Feathertouch focuser with dual speed (but non-rotatable), very smooth, helps accomodate reaching best focus. By far and away, the best of these.

...and one of very few scopes made, including the very finest apochromatic refractors of any make, that qualifies as a superapo by the definition of the term(well, superachromat technically, but that is rather misleading itself).

Hard to argue with that. My A&M/LOMO 80/480 was a nicer instrument in general (nicer tube, better focuser, etc.) but the 80/600 I have now pleases me even more despite the Long Perng tube and focuser.

I don't think one can discuss this topic without including both the TV 76 and TV 85 though they are on either side of the 80mm the op mentions.
The thing about the Tele Vue approach is that it looks at the whole experience of observing. World class optics, world class build, world class ease of use, and world class customer service.
I love looking at all the competitors out there but have found no need or desire to leave the TV camp where refractors are concerned.

I'm not sure, but I thought Cygnus72 was asking what the best one is that we own. If all you have is a Chinese mass produced 80mm long tube achromat then that would be it. A lot of people enjoy looking at the night sky without spending four grand (nothing wrong with spending four grand on a scope, of course!  )

I agree with the others, the 80/600 Lomo is he best 80mm I've owned or looked through. I owned the Stellarvue version as the SV80L. Flatter field than the 80/480 as John mentioned, neither show any color in or out of focus. For me the 600mm was just a more versatile visual scope than the 80/480 LOMO I owned, a TV 3-6mm zoom gave a great range of useful magnifications. Of course, the 80/480 LOMO is a great companion to a larger scope for its wide FOVs and is also a great imaging scope.
Never should have sold my SV80L but feel that the SV90T provides as good of a scope with a little more aperture.

Takahashi FS-78 (if ya don't mind losing a couple of mm's).
At f/8.1, the field is very flat.
Contrast is exceptional.
Color correction is "thinks it's a triplet" class.
I'm not saying it's be best, but sure rates in the top group.

Y'all think Tak'll come out with a new 3-inch-class refractor anytime soon? How long now since the late great FS-78 was yanked off the market?

I've got the same scope. I don't know about the best 80mm scope, but it's definitely easy on the wallet and its long focal length really minimizes CA. However, I have to admit I'd still like to get one of the short focal length ED scopes everyone's always raving about, mainly for the low mag, widefield views they provide.

I have the Lomo 80/600 super apo triplet. I hadn't had much first-hand experience with many 80mm scopes before I got this one, so I don't have much to compare it to. The weather has been relatively poor during the past year since I got it, so have only had it out about a half-dozen times or so. It is very sharp, and the bright limb of the Moon has no color. I've taken it to 400x on Jupiter when conditions permit, and it will bust open tight doubles beautifully. I just got a DSLR so this weekend I'm planning (weather-permitting) to mount it on the G-11 and shoot the Moon with it.
The scope has been sold in a few different flavors but IMO deserves nothing short of a Starlight focuser.

I'll place my vote for the 80mm F8 Vixen Fluorite (FL80S). I have compared it to every 80mm on the market save a few of the most recent Chinese offerings and have never thought I should "upgrade". Going strong since 1987.....

Another vote for the Takahashi FS78, yet I've looked through Jason's Vixen FL80S many times and it's hard to fault it in any way. I'm not a fan of the Lomo's, but I'm not a fan of any short focal length scope I've tried. Though, I can understand how an imager might feel differently.

I really think of the FSQ85 as an imaging scope. It is serious overkill for a visual observer. But I have a dream that Takahashi has on their drawing board a light, 80-85mm FPL53 doublet, compact but not as fast as the Baby Q or the Sky 90, maybe f/7, as a visual observer's true successor to the FC-76/FS-78.
Uh, wow... only after setting that down on (electronic) paper do I realize of course such a scope is essentially already there, it's called the TV-85...

I am partial to my Stellarvue SV80L - Lomo triplet at 80/600. I haven't checked out many others, but when I tested it against a TV-85, I kept the Stellarvue. Perhaps that was partially because of the Feathertouch focuser in the Stellarvue, but I did like the lighter feel/smaller OTA diameter of the TV-85 (because no baffles?). But my weather conditions are so bad often that I suspect I couldn't truly put good 3" telescopes to a good test.

I've not had a lot of 80mm scopes, just three and two were achromat/enhanced achromat class. The third though is the APM 80/480 (f/6) and quite superb. Although I haven't searched for color there is none in routine use at magnifications from 20x to 320x on Luna -- so the in-focus limb showed no obvious color other than lateral color from the EP in the off-axis. Stars very pinpoint and doubles are just a joy to observe. Feathertouch focuser is exceptional and very sturdy feel to all its components. The added plus that I really like having at the ready is that the tube splits so you can shorten it and then use binoviewers without the OCA/amplifier so you get to keep all your TFOV from your eyepiece. Also a nice touch is that it has both baffles and flocking inside...and the baffles aren't any flimsy thing but good solid thick guage metal that are easy to access if need be. So being able to go from 12x @ 5.46 deg TFOV using my 40mm Titan-II ED all the way up to over 300x on Luna using my Radians, Supermonos, or Plossls on my 4x Telecentric makes it a pretty much do anything scope. Plus with the 24 Pan giving 3.2 deg TFOV I've not yet had a need to get a finder scope for it as that has been wide enough to find most anything without effort -- very much point and shoot

It's too bad that they couldn't keep making them as well as Takahashi and their fluorite series as well.
When you look at all the answers in this thread, there are sure a lot of high end choices for us even if some are only on the used market nowadays....

I had a Celestron ST 80. It made a nice, low power, finder. Had an Orion ED80. It was nice but got soft at mags above 150x. I currently own an SV80S with the Lomo objective. It's the last 80mm scope I'll ever need.

Let's put a price restriction in place to make this question more challenging and/or relevant for our pocketbooks. What is the best 80mm scope for less than $500? (Can include OTA-only scopes as well!)

Let me guess Doug...60x900 and 80x1000, although the difference in length looks like a little more than 10 percent.

Well, my Stellarvue 80mm ED Next gen certainly fits the bill for me. Minimal FC if any at all. The mag can be cranked up pretty good before anything bad happens. Great build quality. Fair pricing. Service is as good as anybodys, no question.
Other than a mega high-end triplet, I dont think Id get more enjoyment out of anything else. Actually, I wont upgrade until I can get a 4" Triplet.

I figure it should perform as well as the FSQ-106; correction at least as good as the LOMO but an even wider field - and flatter. It's probably not very significant for visual use, but the request was for the best.

Yes, it's a great little scope. I put it side by side with my new NP-101 and noticed as far as eliminating CA, it matched pretty closely the far more expensive Televue. Although it wasn't as bright, images were tack sharp. Only problem is it doesn't have as flat a field as the 101. I notice stars start to go out of focus nearing the field stop on my 13mm Ethos. Not bad, but the NP is just so perfect in that regard that it's hard to beat it.

uhmmm I disagree with you. IMHO the FS 78 is better than TV85. I compare this two and in contrast, resolution and image detail the little Tak is a winner . Yep I got one and it´s my precciooooouuuuuuuuuussss!
An astronomer fellow in a club that I have visited several times has a Tak TSA 102 and a FS78. We observed together in several nights and I had the chance of compare my TV85 against this two very great Tak scopes.
With respect to the FS 78, while an awesome scope, I can`t say that it outperforms the TV85. The TV85 was a little brighter, obviously in reason of its bigger aperture, and the Tak showed a bit less CA (although the TV85 showed too little so that it matters), I suposse for its minor aperture and longer focal length. Both of them yields beautiful, contrasting and sharp images in each target. But the FS78 seemed to me big and cumbersome for its aperture.
And look in this review how good -according the reviewer- is the TV85 when it compares to the legendary Astro-Physics Stowaway 92mm.
It is NOT possible that you or anybody can be wrong with the Televue 85.

I don't know if suspect, but certainly not an even-handed compare. First off the AP was not masked to 85mm, so that throws off the compare right away. In my own tests between various scopes when I do a compare between ones with slightly different apertures, the results always fall the way it did for this compare, the larger aperture scope appears better on stars, globs, etc., and the slightly smaller one always seems to do a tad better on planets (which I surmise is because the little less brightness does accentuate surface feartures most of the times when doing direct compares and does make the background space look more stark). Other confounding variable was the use of two different brand diagonals between the scopes. So would have been a more "level" compare if the same eyepiece/diagonal combo was used for both, and if the apertures were masked so equivalent. So IMO this review needs to be read with these things in mind. Still a very interesting compare.

It sounded as if the seeing wasn't very good and that it was coming and going quite a bit. It is difficult to get good comparison results when the seeing isn't very good and is changing rapidly.
Maybe that particular Stowaway had a problem but the results of the review don't fit my experience. I've looked through several TV-85s they are very nice, but I also know that my f/7 Stowaway gives outstanding views.

I recommend a Stellarvue SV85S. I own one and am always amazed at how well it performs for a doublet. It can certainly hold its own against some of the newer triplets that I have viewed through. I prefer to use it on an AltAz mount for portability reasons. I just ordered a Desert Sky Astro Mount for a grab and go. The views through this scope with a 22mm Nagler T4 are breathtaking!
In fact there is one for sale on A-mart:

That's a great collection of small scopes. Of those, the one that I would save from a burning building is the FS-78! I love doublets--especially small ones--since they cool so fast, and always being ready for action is part of what small scopes are about.

Your statement and the Bill one are right. But, IMHO, that only demonstrates the fact that the TV85 is so good that to compare it to very high-end triplets, larger in aperture, even must be made in carefully controlled conditions. It is easy to forget that the TV85 is only a doublet…

Sorry, I am a pathetic fundamentalist.
Yet you speak the truth. When I got my NP-101 and compared it with the 85, I soon discovered the smaller scope matched up pretty well. Yes, it does show some CA when a bright star is highly magnified, but for the most part, I don't see any CA to speak of. None with the moon. Mostly it's dimmer than the 101. It still resolves images with the best of them.

I'll place my vote for the 80mm F8 Vixen Fluorite (FL80S). I have compared it to every 80mm on the market save a few of the most recent Chinese offerings and have never thought I should "upgrade". Going strong since 1987.....
Nice scope had one and foolishly sold it. I also had a Stellarvue SV80S very nice but I really liked the longer FL of the Vixen 80mm Fluorite. I ended up selling to 80mm f/6 LOMO and replacing it with a SV90T Fluorite. At 630mm the FL is almost the same as the Vixen was but I have 10mm more aperture, sliding dew shield and a Feather Touch on the Stellarvue.

My WO 80mm 480mm F6 Triplet with Lomo Super APO Optics is the best 80mm I have come accross. In 2005 when I bought it WO advertised it as a Flourite Triplet which was misleading and contriversial at the time. In any event I kept it and it has never let me down. I will never part with it.
