Product Description
Stellarvue's SVX152T is a hand figured, high resolution telescope. This is an exceptional visual refractor that produces amazing images when used with the Stellarvue photographic field flattener.
Focuser Selection:
- The Stellarvue 3" focuser. This focuser has 4.5" of travel and 2" and 1.25" compression ring adapters. This is our brand focuser that is well known as a stable and smooth 3" focuser with a highly accurate 8 to 1 reduction that allows absolutely precise focusing. This is the same as used on our smaller aperture telescopes. Both Optec and ZWO motors attach directly to this focuser allowing even more precise focusing.
- The Starlight Instruments 3.5" focuser, with 4.5" of travel and 2" and 1.25" compression ring adapters. This is an American-made focuser that is equally smooth to the focuser above but is larger. Both Optec and Starlight Instruments make motors for these focusers.
- The Moonlight Nightcrawler 3.5" focuser with various extension tubes and 2" and 1.25" adapters. This is an advanced, electronic, computerized focuser preferred by dedicated imagers. It is the most expensive upgrade, but for those who want perfection when it comes to imaging, this is considered one of the best. The downside is a very short focuser draw tube length which is great for imaging stability but requires various extensions when converting to visual use. Since most high-end imagers rarely or never look through their instrument, this is usually no big deal.
*Please note that the default color for the Nitecrawler will be RED unless specified otherwise. For a full list of available color options visit www.focuser.com.
Photographic Field Flatteners
Purchase photographic field flatteners when you buy this telescope and save up to $300. Merely select the options at the top of the page to add these photographic field flatteners.
Field Flattener: To image with this telescope, use the SFFX-3 photographic Field Flattener.
Reducer Flattener: To image at f-6, we currently offer the SFFR.72 photographic field flattener/reducer. This is an imported unit sold by a number of sources on the market. It is the best unit we have found so far. Based on the success of our in-house field flatteners, we are currently working on a new in-house reducer/flattener that will have the same optical specification as our flatteners. We expect to have this unit ready in early 2025.
When you buy these photographic correctors with the telescope, we will include the necessary adapters needed to attach to the focuser you have selected. We will contact you to determine your camera thread size and back focus. We will work with you to get the flattener and reducer/flattener matched to your camera.

This is a premium refractor
I bought this telescope 2 and a 1/2 month ago.the scope arrived exceptionally clean. Not a spec of dust to be seen anywhere. It's a small detail but it does inspire confidence that the scope was assembled by professionals. I was able to test it only briefly during that time due to work schedule and lack of clear nights. Last night, I had it side by side with my edge 9.25 HD on a Rowan Astronomy AZ100. Seeing was steady and I began the process of alignment of the mount between the moon and Polaris. Polaris was beautiful looking star with its little companion with a 8mm Delos eyepiece. The moon was very sharp with contrasty features as well but then I switched to a 3.5mm Nagler and it was even better. For fun, I added a 2x Barlow to the mix and to my surprise the image remained sharp and no chromatic abberation whatsoever. The ultimate test will be on Jupiter maybe next year. Note: this scope works better with a prism diagonal at least to my eyes. Glad I returned an espirit 150 to buy this scope. They're not in the same league.

SVX152T - Terrific optics
I have had a chance now to use this on two targets, and am amazed at the quality of the optics. The images' FWHM are frequently in the 1.5" range, at the limits of my seeing. After working on tilt and back focus a bit, the corners are sharp, round, and minimal vignetting (with the SFFX-2 flattener) on a full frame camera. Everything is built like a tank, the nitecrawler is a great companion for the OTA, the rings are heavy duty, and the dew shield is a bit of a monster (which I need as I image in a swamp). I did replace the somewhat short dovetail with a longer one, but the short one worked fine in a couple weeks' of us (the longer gives more room to balance, e.g. switching from a long imaging train to visual). All in all it is an impressive work of art.

Stellarvue SVX152T with Optimus Eyepieces
Stellarvue SVX152T, 2” Dielectric Star Diagonal, Feather Touch Focuser and complete set of Optimus Eyepieces with Case. The scope & equipment came very nicely packed and in excellent condition, and on time. Superb quality and finish. Excellent communication. Vic ordered me a Losmandy G11G mount as well. Very pleased with it also. At first light, I took it out and everyone was amazed at the views. The quality and superb optics of this scope beats my 12”SCT. Stellarvue has now become my official goto scope. I am overjoyed. Thanks go to Vic and his entire Stellarvue team. Thank you very much, Gary It took six months to polish and figure your objective and the entire team is very happy that you are enjoying your new world-class refractor. Thank you for your review. We are here if you need anything. Clear, steady skies Vic Maris President Stellarvue

SVX152T
Superb design ... flawless execution. This premium telescope is worth the wait and the cost! Images are free of chromatic aberration, rich in contrast and views of the Moon and planets are stunning. This instrument delivers textbook Airy disks and separates tight double stars with ease; under steady skies I have often used magnifications of 347x / 58 power per inch and the subtle colors of Almach, Rasalgethi and Izar are simply beautiful. Globular clusters sparkle with three dimensional effect. This telescope virtually steals the show at star gazes and garners rave reviews from experienced observers and novices alike. The Stellarvue rack and pinion focuser is smooth as silk, with a full 100mm of precision travel. The 13" Losmandy-style D-plate and 1" thick tube rings provide rock solid stability on my G11 and Meade LX850 mounts. The travel case is a beast that securely cradles the telescope for extended road trips, but at 53" total length and given the weight of its robust construction, it's a two-person lift in and out of my SUV. ( I crafted my own padded tie-down pallet for local transport ). The Stellarvue team has a winner with the SVX152T and I couldn't be happier with this gem of telescope!

Perfectly Executed
This scope is exactly what you would expect from Stellarvue: a perfectly executed example of a refractor. The contrast on faint objects and on planetary detail is exquisite. Subtle shading differences are easy to pick out. On nights of good seeing, the scope can be pushed to high magnification and delivers beautiful pinpoint images. I stepped up from a 102mm Stellarvue refractor to this and the jump in light gathering power is just what I wanted. There’s more detail on faint structures and I can reach much fainter stars when star hopping. There’s also a nice resolution boost on nights of good seeing as the airy disk is smaller than the on the 102. I love that I now have more aperture reach while also being able to observe while seated. I’ve found that seated observing makes a big difference in my ability to really study the images and let my eye pick out fine detail. This scope ticked every box that I was hoping it would!
