The Stellarvue Access 80 mm telescope is your chance to own a high-performance Super ED Apo at an affordable price! It uses a unique combination of materials to keep the cost down without sacrificing usability. The objective contains an apochromatic doublet using a combination of Hoya FCD100 and Lanthanum which will keep your image contrast high, and since every lens is aligned before shipment you can be sure that you’ll be getting color free visual performance, but without the higher price. With the 2.5 inch focuser you’ll be able to handle any combination of diagonal and eyepiece. Also, with the superior design of the rack and pinion focuser you can be assured of smooth yet stable draw tube travel.
Tube and dew shield: The Stellarvue Access 80 comes with an aluminum tube and dew shield that is finished in Instrument White. Fittings are black anodized aluminum. The dew shield retracts reducing the length of the telescope when being stored. Extending the dew-shield minimizes dewing of the objective at night and serves as a glare shade during the daytime.
Internal tube treatment: The inside of the main tube assembly is painted "ultra flat black" and is baffled to eliminate tube wall reflections.
2.5" Stellarvue visual/photographic focuser: Our new smooth and stable dual speed, 2.5” focuser provides a full 3.5" of travel. This focuser is perfect for visual use and imaging. The rear of the draw tube will accept our dedicated reducer/flattener (SFFR-80A) or will thread in with the optional rotator for an additional $59. The Stellarvue focuser is a heavy-duty rack and pinion unit designed to carry a higher capacity. It has an ultra-smooth (10:1 Ratio) fine focus control to attain perfect focus every time. An internal brake system allows the user to adjust capacity. All of the features add up to one of the finest dual speed focusers available today.
Aluminum hinged rings: The Access 80 comes with two lightweight, hinged aluminum mounting rings. Each ring has 6 mm threaded holes top and bottom. There is one center hole and two holes spaced 38 mm apart. Use the included rail for telescope mounts using the Vixen style rail or use the optional TP6 for mounts that use the larger Losmandy style rail.
Vixen Style Rail and Balance: The Access 80 comes with a Vixen style rail with a center 1/4-20 threaded hole and several holes and a slot to permit positioning rings for the best balance. With heavier accessories position the rings closer together.
Case: The SV080Access comes with a thickly padded, C20 airline carry-on case. Outside dimensions: 22" x 9.5" X 7.5". Inside dimensions: 19.5" X 6" X 5".
Light gathering and magnification power: An 80 mm refractor gathers 131 times the amount of light the naked eye does. Although Dawes limit states maximum power for telescopes under good conditions is about 189 power for an 80 mm telescope, you can exceed this power on a steady night. Check the Recommended Accessories section to make the best choice for eyepieces.

I have owned refractor telescopes before, but none have come as closed as this one to the clarity of the skies I have seen as with this scope. I just wish I could get more clear nights to use this scope. I can only imagine what the Premier APO telescopes show. That will come later, though at 76, I believe I will stay with this size.
The only area, which was my fault, is that I did not look at the photo close enough to be sure what type of focus it had on it. The brand new ones have a general and a fine adjusting focus and this one just has the general focus (no fine adjusting). Though I have never had one with this added feature it would have been a plus for this telescope.
I love taken telescopes to schools and having children and others come to the house to view the sky, and I am sure this telescope will open some eyes to the wonders of God's creation.
Thanks for a great scope
I already posted a review of this scope nearly two years ago when it was new, but I'm writing again because I've found Stellarvue's customer service to be so excellent that it deserves special mention. In my original review, I gave the scope five stars because of its great performance and very reasonable price, but I also noted that my star test had shown some spherical aberration. Just recently, I looked back at this web page and noticed that Vic had responded to my review, offering to test the lens and replace it if it wasn't .95 Strehl or better. So I decided to take him up on the offer. I sent in the scope, and now it's on its way back to me with a new lens!
I bought my scope before Stellarvue started including a Zygo test with the doublet lenses, and I had no reason to have expectations as high as .95 Strehl. (A common standard for optical quality is .8 Strehl; this is often what's meant by "diffraction limited.") My original lens must have been very close to .95, because Vic said in his email to me that the new one is a few points higher. So this isn't a case of a manufacturer replacing a defective product because they obviously must. Rather, it's a case of a manufacturer voluntarily offering to replace a product that falls just slightly short of a very high standard, which wasn't even guaranteed in the first place.
So I'm a very happy customer. The views were great to begin with, but now they'll be even better--just in time for the best opposition of Mars in 15 years!
It's also very exciting that Stellarvue has now added bigger telescopes to the Access line. If I ever buy another refractor, it will almost certainly be another Stellarvue. They're the perfect company--somehow able to provide a level of quality and personalized customer service that one would expect to come with a much higher price tag.
So here’s the deal.
I had a SV80ED carbon fiber. Used and enjoyed it immensely for 5 years. But I wondered if SV’s newest iteration would be a worthy upgrade. Alex, who replied to my queries, said yes, it would. Substantial improvements both both optically (FPL-53 and Lanthanum vs FPL-51 in my circa2012 SV Raptor) and mechanically.
I thought about for a bit, then sold my beloved carbon fiber beauty and ordered an Access 80. Then I waited. And waited. And waited some more for a clear night in Western Oregon. Got one last night, so I had my first light adventure with the Access 80.
Know what? Alex’s assessmnent is true——and then some. 100% spot on. Mechanically and optically..and aesthetically as well, the Access 80 is a flat out JEWEL of a refractor. The R&P focuser is a beast——strong and smooth and sans slippage, any at all, even at zenith (vs the Crawford in my former SV80 that did tend to backslide occasionally under some heavier EPs).
So I spent a joyful 2 hours traipsing around in Orion, Monoceros, Canis Major/Puppis and Perseus. In three letters: W.O.W. Precise pinpoint stars everywhere I stopped to stare: bright blue and yellow dots in the CMa double H3945 (what a prosaic name for something so beautiful); the trapezium never looked more clean and sharply defined, ditto the Struve 747 and Sigma Orionis triples; M41, M46-47, M35, the Alpha Persei Association, Double Cluster, and on and on. Everywhere I looked I was served up, in one sense, to almost a first time experience, so impeccable was the resolution and the contrast.
I am able to use a green laser pointer (in a dovetail bracket using the Vixen foot that comes on this scope) which, paired with a 2” 30mm uwa eyepiece, makes the Access 80 its own 18mm finder .
Both my 24mm/68 (23x) apov and 19mm/66 (29x) eyepieces produce wonderful wide field vistas of both target object and surrounding starry context, so low power with the Access 80 for the best overall celestial tapestry, while my 11mm/82 (51x) provided a darker backdrop and the most complete object portrait in terms of overall configuration and number of stars. High power (6mm/66 (93x) and 4.7mm/82, 120x) found almost no drop off in resolution.
Focuser movements are tight and precise; I could easily make the tiniest of micro-adjustments that moved the object from 99+% sharp focus to full on, well, perfect. I expected the optics to be good.....just not quite THIS good. And I mean Good in an absolute sense, not denuded by one of those “for the price” qualifiers.
My Access 80 feels heavy——heavy in the good way as in solid, substantial, a real presence to it. No corners cut anywhere: fit and finish, overall buildi quality are outstanding. And count me among those who prefers the ota-matching white focuser, so the same eye-pleasing aesthetic end-to-end.
If I have any kind of a gripe, and I have to really do some reaching here to find one, I wish that the padded case was 2-3” longer with a divider to accommodate a 2” focuser.
But that’s it.
I could not be more satisfied or excited. Can’t wait for our first string of clear nights.
And thanks Alec, Sarah, Vic for exemplary customer service.
Looks and performs great.
I bought this scope for travel and it works perfectly with my Ioptron smart star Cube Pro mount that has a payload of 12lbs with the counter weight. Observing at 21.5 SQM is as good as my 8" VC200L at home with an SQM =20. I used Pentax XL eyepieces. I found 2 minor problems, one is with the rotator that doesn't allow focus with my long 2x Siebert barlow, the other problem is the stellarvue 1.25" diagonal is so tight that sometimes I am having trouble to remove my 19mm Panoptic from the diagonal. The optics of this scope I found are excellent for visual.
This is a repost from my Cloudy Nights review of 08/11/16:
First Light - SV80A
There was quite a bit of smoke covering much of the Central Valley yesterday due to the numerous wildfires along the central coast and interior. That being said, as dusk fell, much of the smoke moved west and the sky became marginally clear overhead and to the east. I decided to give it a go. Bear in mind that I have never used a refractor before. I've always been a reflector kind of guy and only recently acquired a 180mm Mak-Cass, which I use almost exclusively for solar system viewing and imaging.
First Impression: I set up, aligned and then put in my Stratus 17mm. I went first over to the waxing Gibbous moon as it dominated the SW sky. The night before, the smoke was so bad that it was orange. Tonight it was much better. The first thing I was struck by is how sharp and clear the image was. At 32x mag I could make out every detail that was in view. The shadows cast by Montes Apenninus and Montes Caucasus were so sharp that I was a bit mesmerized. I switched to my Stratus 5mm and at 112x mag there was no decrease in sharpness. I moved along the terminator from north to south. One difference I noticed right away was the increased sharpness and definition of crater wall edges. I put in my 4-element 2x Barlow with the 5mm. Though the motion of the heat waves began to appear, there was no decrease in the sharpness or clarity of the images. There were no chromatic aberrations throughout the FOV using the 17mm or the 5mm eyepieces.
I then slewed over to Saturn. I started with my Baader Plantarium 24mm. Stars in the FOV were sharp and pin-point. I could easily make out Titan and Saturn was clearly defined with ring sharpness and separation from the planet proper. I moved up to the Stratus 8mm. Titan, Dione, and Rhea were clearly defined. There was no change in color and I could easily make out the Cassini Division. At 5mm the view was still sharp and I could make out three distinct color bands and Rhea. Again, there was no CA or distortion at the edges of the FOV in any of the eyepieces.
Leaving the 17mm in, I worked my way around from SW through north and then to the east. I paused at M3, which was a bit difficult to resolve, but this was due to the LP and diffusion from the residual smoke. I wanted to see a large star field, so as it was darkest and clearest in the east, I slewed over to Cepheus and Lacerta. I quickly realized that my 17mm EP was going to be my favorite for this kind of observation. I moved along in a southeasterly direction pausing occasionally to look at some of the denser star fields. When I reached the Cygnus Star Cloud, I realized that I had truly discovered what refractor aficionados were always raving about. There was almost no field curvature and the stars were pinpoint. It was a very satisfying view.
I decided to do something I had never done before. Split binaries. I checked my handset and chose Zeta Aquari and put in my 5mm EP. One of the things I had to contend with when viewing through my 8" f/3.9 astrograph reflector was astigmatism. I could never quite get stars to be truly sharp and round at higher magnifications no matter how well I collimated. With a little fine focusing, I was able to split the pair. They were sharp and pinpoint with no astigmatism or CA.
Next I went over to T Cyg (65 Cyg), a pulsating binary. Again, with the 5mm, I split the pair, though it was very tight. Fortunately, the SV 2.5" dual speed focuser was sensitive and fine enough to just get the two to split.
Lastly, I went to Mizar. I had saved this for last. When I first began observing with my 8" reflector, I remembered reading somewhere that it was actually a binary star system. When I first looked at it with a 10mm EP, I thought I was "splitting" the pair since I could make out Alcor. It seemed logical at the time since Alcor wasn't visible in my area to the naked eye. After I learned of my mistake, I tried on several occasions to split Mizar with my reflector. The closest I ever came was a fuzzy little oblong bulge on one side. Tonight was different. Using the 5mm EP, I split it easily. Again, no CA and no spiking.
The smoke was beginning to waft back from the SW by midnight so I packed it in. Overall, I have to say that I was very impressed with this scope. I probably missed a few tests I could have carried out, but it all boiled down to this:
I like this scope. I like the views it gives and the sharpness of the images. The wide field experience is very different from what I'm used to and although I was warned about field curvature at lower magnifications, I honestly couldn't see any.
When the seeing and transparency improves, I'll have a chance to see how it performs with imaging. But, if last night was any indication, I'm sure I'll be pleased with the results.
Cheers and Clear Skies -
I chose this scope because I wanted a lightweight, quality refractor to use both for astronomy and for watching wildlife. I have it mounted on a Universal Astronomics DwarfStar mount atop an Induro CLT403 carbon fiber tripod. This setup is stable enough, but vibration suppression pads are still helpful. The DwarfStar mount is very smooth and pleasant to use.
The views of birds through this scope are truly amazing. With a 24mm Panoptic eyepiece and a 60-degree Everbrite diagonal, the image approaches naked-eye quality. Furthermore, imperfections in this image (such as distortion and slight lateral color) clearly originate in this famous eyepiece, not in the scope. At night, my favorite eyepiece is the 20mm Stellarvue Optimus, which is spectacularly wide and comfortable to look through. Only having had the scope for a week, I haven't had a moonless night yet. But even in bright moonlight, it's clear that this combination is fabulous.
I also did a star test to evaluate the optical quality of the telescope, using this web page as a reference for checking the diffraction pattern: http://www.telescope-optics.net/star_testing_telescope.htm
Here is how the scope did with respect to the major aberrations:
--Chromatic aberration: none in focus! Outside focus, bright stars do show subtle blue and red fringes on the brighter diffraction rights. To be expected, and not a problem at all. I also didn't notice any CA on the lunar limb, but this observation was complicated by the difficulty of positioning my eye precisely enough to eliminate all traces of eyepiece-caused color.
--Astigmatism: none whatsoever.
--Pinching: probably none. I sometimes had the impression that the diffraction rights were not quite round, but this could have been a thermal or seeing artifact. In any case, it's extremely subtle.
--Spherical aberration: here's where the telescope did show an imperfection. The spherical aberration was clearly visible. Inside focus, the inner diffraction rings are bright and well-defined. Outside focus, they are faint and fuzzy, but the outer ring is bright. Not being an expert star-tester, I cannot say for sure whether I saw primary or secondary spherical aberration (though I suspect secondary), and I cannot say just how much there was. However, looking at the examples on telescope-optics.net, I think that somewhere between the levels corresponding to 0.8 Strehl and 0.95 Strehl is a reasonable guess. From my understanding, even 0.8 Strehl is not bad performance, and 0.95 Strehl is the "perfect" level guaranteed by Stellarvue in their more expensive scope, the SV80ST. For this reason, I am not overly concerned about the star test result. A small amount of spherical aberration, though obvious in a star test, has the same effect on in-focus images (brightening of the diffraction rings) as does adding a central obstruction. So perhaps, this scope is behaving more like a perfect small reflector than a perfect small refractor. A perfect small reflector, such as a Questar, can cost more than $4000. I'm not saying a Questar isn't worth that (though perhaps it isn't), but I do think this comparison points out what a good deal the SV80A is. I don't think the spherical aberration is a compelling reason not to get it.
The telescope is also beautifully made. The focuser works well, the dew shield slides smoothly, and it comes with an extraordinarily nice case. In all, I think it's an excellent choice. Had it cost $1200, the star test would have prevented me from giving it 5 stars. But because it cost only $700, I think it deserves 5 stars.
REPLY FROM STELLARVUE:
Thanks for the excellent review. The only question is with the optical accuracy which should be around .95. Sometimes if a lens has not cooled it will appear this way but the 80 apo doublet cools quickly. I think you should return the telescope to us for a Zygo test. If it is not .95 or higher I will replace the lens. We are now adding a Zygo test to these doublet lenses to ensure they meet our standard. Let's make sure something is not amiss with your telescope by taking advance of our advanced test equipment. We want your telescope to perform as it should! Vic Maris
The optics are very good. Detail on planets and splits on doubles are the same as the Stellarvue 80ED with the improvement that the slight purple fringing on very bright objects has been eliminated by the FPL53 glass. Unfortunately the balance of this telescope is the worst of any small scope I have used. It is back heavy with the diagonal attached and very sensitive to changes in eyepieces which easily throw it off balance. This is very problematic for mounting the scope. The rings can not be shifted down very far and the rail is too short to compensate. Perhaps a longer rail would help.
NOTE FROM STELLARVUE: We were remiss by not showing how balance is achieved on the website and I have now posted that. Since this telescope uses an upgraded 2.5" focuser which has many advantages, it is back-heavy. To compensate for this we include a rail that can be attached in different places (as now shown on the web) moving the balance point to the rear. We also placed the rotator on the draw tube to eliminate the focuser knobs interfering with the rail. We wanted the larger focuser for imaging. This telescope has a dedicated flattener that threads to the 2.5" focuser. While an even longer rail would allow wider ring spacing, the existing one works with our 2" diagonal and 100 degree eyepieces with the balance point below the rear ring.
