SVX152T

Product Description

Stellarvue's SVX152T is our most popular apochromatic refractor. Each optic is carefully figured to the highest optical accuracy. Interest in this telescope continues to grow. Over the past year we have trained several opticians to meet this increased demand while maintaining the SVX standard, without any compromises. This has shortened the delivery time for new orders!

Focuser Selection:

1. 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.  
2. 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.  
3. 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 ww.focuser.com.

Financing: Since this telescope is not immediately available it cannot be financed. However, when the telescope is ready to ship, financing for the balance can be arranged.

Rings: Our CNC machined rings are strong and stable, made of 6061-T6 aluminum. Cast rings can break; our rings never do. 

Rail and Case: Each telescope comes with our Losmandy-Style 13" D plate and a heavy-duty, American-made, roadie-style case with wheels, a handle, and solid 3/8" plywood walls. This is a durable and strongly-padded hard case; it is not the typical cheap import case. 

Finder scope: Also included is our F050W2 finder scope with R050DA finder rings. 

Optical Imaging Accessories

Field Flattener: To image with this telescope at 1200mm focal length, use the SFFX-2 if you are purchasing a 3.5" focuser and use the SFFX-1 if you are ordering the 3" focuser. The SFFX-2 is too large to fit focusers smaller than 3.5". 

Reducer Flattener: To image at 900 mm f- 6, use the SFFR.72 photographic field flattener/reducer. It produces a full frame (42 mm) image circle. 

"I just took delivery of SVX152T s/n 004, and it was well worth the wait. Contrary to the first law of new telescopes, we had a brief interlude of clear skies with outstanding seeing. There were intermittent clouds forming so there was no time to dwell on any one object. I tended to associate “pinpoint stars” with marketing hype, but damn! This scope is awesome. The Orion Nebula revealed fine detail and the Trapezium stars were tiny dots. The Double Cluster in Perseus had that pearls-on-black-velvet look and drew oohs and aahs from my wife and neighbors. Mars and Uranus presented well-defined disks when viewed through the Stellarvue 4.7mm Optimus eyepiece. M1 was another interesting item that stood out clearly with good definition. However, the most telling observation I made was when I turned the SVX152T on Rigel with with the 4.7 mm Optimus. The scope really set up well with my Astro-physics Mach 1 mount and even at this high magnification I was dropping objects right in the center of the eyepiece. I selected Rigel because I want to see how the scope handled a really bright star. As expected, there was no chromatic aberration or distortion. Almost all of the light energy was concentrated on a tight point with a faint airy disk. I wasn’t even thinking about Rigel B, and I was stunned to see it pop out so clearly. This truly is a great scope. My thanks to Vic Maris and the Stellarvue team for producing such a fine instrument."
