## Overview

The Orion 05640 Superwide 2-Inch Prime Focus Adapter is engineered for Canon EOS cameras, providing the widest clear aperture for full-frame DSLR imaging. With a 10mm optical length and a tapered design for secure attachment to telescope focusers, this adapter ensures exceptional contrast and clarity, making it an essential tool for serious photographers and astrophotographers alike.

## Description

Optimize your DSLR astrophotography setup and take full advantage of full-frame sensors with this handy adapter. The super wide 2" Prime focus adapter provides the widest possible clear aperture to minimize igniting - darkening around the edges of the image sensor - in photo exposures, even when using cameras with large, full frame sensors. Nearly 10mm wider than standard t-adapters and t-rings, the Orion super wide 2" Prime focus adapter boasts a clear aperture of 47. 5mm for great DSLR imaging performance. Consisting of a 2" T-adapter with an integrated Canon EOS bayonet, this useful prime focus adapter allows secure attachment of any Canon EOS DSLR camera to a 2" Telescope focuser. Unlike standard t-adapters that utilize a 42mm t-thread and often have an even narrower clear aperture, the super wide 2" Prime focus adapter doesn't restricted the attached camera's field of view, meaning APS-C and full-frame cameras can be used to their full potential without suffering from igniting. Its unique tapered barrel provides an extra-secure connection to keep the adapter and attached camera from detaching from a telescope should the focuser collar thumbscrews become loose. Made of machined, Black anodized aluminum, the super wide 2" Prime focus adapter features internal glare threads and a flat Black finish to help reduce reflections for excellent image contrast. Adds only 10mm of optical length to astrophotography setups when installed, and weighs just 2. 2 ounces. Threaded for use with 2" Orion filters.

    Gets the job done
  

*by B***N on Reviewed in the United States 🇺🇸 on February 12, 2014*

I'm farily new to astronomy so pardon if I don't use the actual technical terms.  This is a good product, it gets the job done, it's really stable and holds my D7000 very secure, however, when using the 10mm and 7.5mm eyepieces, I find that I cannot focus since this tube is too long...easily fixable though, I just unscrewed the bottom part and screwed the adapter directly into the telescope.  I also noticed it's a little too short to fit the 25mm eyepiece I have, but no matter the 20mm and below fit just fine.

    Star Struck!!
  

*by T***J on Reviewed in the United States 🇺🇸 on January 4, 2015*

Works exactly as it's designed. I use it with my 28mm Sirius Plossl eyepiece. Got some great photos of the moon last night. The only thing I have a problem with is getting a full moon all in one frame. The picture is very crisp though. I'm thinking about adding a 32mm eyepiece to my set so I can have a full moon all in one frame. It would also be helpful to have an eyepiece to leave in the camera adapter the entire time. It's not a very speedy process to remove the eyepiece from the adapter so that I could use it in the telescope. I have not had to use the variable adjustment (magnification) yet. The adapter is very well made and worked great with my Nikon D7100 camera. Can't wait to shoot some planets.

*by G***K on Reviewed in the United States 🇺🇸 on July 19, 2016*

This came to me lightning quick and I appreciate it. Its was bought as an experiment in the works. I have an 8 inch Dob and I am working on a solution to take some video from the telescope. This add on will allow me to experiment with different camera lenses and microscope lenses as well to find that perfect match so videos will come in focus without issue.
