Product Description

Stellarvue’s flagship, the SV152T, is now returning to production. The FPL-53 glass has been melted. Our new, upgraded in house optical shop is being finished and when the Lanthanum elements have been made, work will begin. We have a notification list for those interested in being notified when we will open our wait list. When we open our wait list a deposit will be required. People on the notification list will have the first opportunity to order. We plan to open the wait list around the middle of this year. 50 of these telescopes will be made this year, one at a time.  

To get on the notification list email: Please mark the heading of the email "Please place me on the SV152 notification list."

In the body of your email include the following information:

1. Your full name

The air-spaced apochromatic triplet objective uses Ohara FPL-53 glass. This telescope has the highest resolution and the largest image scale of any current Stellarvue refractor. The telescope comes in a Instrument White finish, has a retracting dew shield, 3.5” Feather Touch focuser with 2” and 1.25” adapters, aluminum mounting rings made on our CNC machines and our heavy duty C152 American made Rodie style hard case. 

Our high Strehl precision made objective and extreme broadband coatings ensure excellent optical performance. This is the highest resolution telescope we make for both visual and photographic use.

The Stellarvue SV152T is a 6" observatory class, apochromatic refractor with a focal length of 1210 mm (f-8). This telescope delivers true apochromatic performance with significant light gain over the smaller telescopes in our line. Photographic performance is excellent. When using an APS or smaller chip no flattener is required. For larger chip cameras, our dedicated SFFR152 will flatten the field and reduce the f-ratio to 5.8! We also have a straight flattener for shooting at the f-8 focal ratio.  

Fully multicoated apochromatic triplet objective: The SV152T provides extreme contrast, a perfect star test, and excellent color correction. To further enhance this high level of contrast, our proprietary, extreme broadband full multi-coatings are used on all six optical surfaces, making the stars appear vivid and the background velvet black. These coatings transmit light above and below the visual spectrum, eliminating reflections seen only on ccd images.

Instrument white aluminum tube and dew shield: The aluminum tube and dew shield are finished in our durable Instrument White finish with contrasting black anodized aluminum fittings. When the telescope is used, this dew shield may be extended to minimize dewing of the objective at night and to serve as a glare shade during the daytime. When being stored, the dew shield retracts to reduce the length of the telescope.

Internal tube treatment: The main tube interior is painted "ultra flat" black inside and has five knife edge baffles to eliminate any tube wall reflections baffled to eliminate excess light reflection. The 11 baffle ridges of the focuser draw tube are painted "ultra flat" black to eliminate the most common type of reflections. This treatment is far better than draw tubes that are merely threaded. The blackened edges of the objective are the final method used to preserve the outstanding contrast of this exceptional apochromatic lens.

3.5" Feather Touch dual speed focuser: The fully rotating, 3.5" Feather Touch offers  4"  of travel. The Feather Touch features an ultra-smooth coarse/fine focus knobs  (10:1 Ratio), internal brake system, ultra-low backlash system. 

Aluminum hinged rings:   The SV152T comes with two American made, cnc machined, hinged, aluminum  mounting rings. Each ring has five screws top and bottom. Threaded holes are  1/4-20. There is one center hole, two holes spaced 1.5" apart and two holes spaced  60 mm apart. Use the optional TP-10 rail for telescope mounts using the Vixen style rail or use the optional TP13 for mounts that use the larger Losmandy style rail.

c152hd-small.jpgC152 Case: A heavy duty, foam lined rodie style travel case is included.  The American made C152 case is of a higher quality than import hard cases that have thin walls. This case will last for many years. It is made with 3/8" thick plywood, not thin veneer.  

What else do you need?  In addition to the supplied  accessories, you will need a star diagonal, eyepiece(s), a mount, and a reflex or optical finder scope.

Light gathering and magnification power: The purpose of a telescope is to gather light and magnify the apparent size of the object being viewed. A 152 mm refractor gathers 472 times the amount of light the naked eye can. This will reveal faint objects in space. Magnification power (the increase in relative size of the object being viewed) is dependent upon the eyepiece being used. Different eyepieces provide different magnification powers. Since this telescope uses a highly accurate, hand figured objective lens and is triple tested in the USA, these telescopes are free of the coma and astigmatism seen in many import telescopes. This provides sharper details when viewing at higher powers. Dawes limit, which is the stated maximum power for telescopes under good conditions is about 378 power for a 152 mm telescope, but you can exceed ever this power on a clear night. This is a true apo triplet capable of very high power, when conditions permit. Check the Recommended Accessories section to make the best choice for eyepieces.

Two year warranty and Stellarvue Service:  Stellarvue telescopes and accessories are covered by a two-year warranty. But it does not stop there. Since we are a telescope maker, we can repair your telescope for a nominal fee years after it goes out of warranty, should you accidentally drop it on concrete or otherwise damage it. Buy a Stellarvue Telescope with confidence. Our customer care is legendary.
