SVX152T

Product Description

Stellarvue's SVX152T is one of our most popular apochromatic refractors. Planning one year ahead and working continuously, we have 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.

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.  

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-2 field flattener if you are purchasing the telescope with a Feather Touch or Moonlite 3.5" focuser. If you are purchasing the telescope with a 3" focuser use the SFFX-1. The SFFX-2 is too large to fit focusers smaller than 3.5" but don't worry, the SFFX-1 will work for cameras up to full frame.   

Reducer Flattener: To image with a wider field at .75X, use the SFFR photographic field flattener/reducer. It produces a full frame (42 mm) image circle. If this reducer/flattener is used in conjunction with the 3" Stellarvue focuser it is necessary to remove the extension tube in front of the focuser in order to reach focus. 

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.
