View Setup Diagram

If your scope accepts 2" eyepieces consider our True-2 adapter instead. If your scope accepts only 1.25" eyepieces this is the correct setup for Prime Focus. The included parts will allow you to couple your SLR or DSLR camera to a standard 1.25" eyepiece port for "prime focus" astrophotography. The money saving combo includes our popular 1.25" prime focus adapter (#T125) packaged along with the appropriate T-Ring for your brand of camera. Parts are "T" threaded for compatibility with many other adapters. All parts are CNC machined of aluminum, coated with a durable black anodized finish and internally baffled to reduce reflections. The 1.25" barrel is threaded to accept standard 1.25" Eyepiece Filters. See our optional clear glass Dust Filter (#T1FLT), recommended to help keep dust out of your camera.

This kit is suitable for:
Prime Focus
96 In this imaging method the camera is connected directly to the telescope and placed at the "prime" focus of the telescope. The telescope becomes the camera lens. No eyepiece is used in this method. This method provides the widest possible field of view, the shortest possible exposure time and moderate magnification. Typically used for imaging nebulae, galaxies and other large (but dim) deep sky objects.

IMPORTANT: Additional parts may be required to reach photographic focus with certain telescope types:
SCTs and Maks generally have enough focus range without any additional optical or physical extensions.
Reflector type telescopes will typically require the use of a Barlow Lens (#BAR1).
Refractor type telescopes will typically require the use of an Extension Tube (#EXT126).

Fits any telescope with a standard 1.25" eyepiece port. The included parts will allow you to couple your SLR or DSLR camera for "prime focus" or "eyepiece projection" astrophotography. Parts are "T" threaded for compatibility with many other adapters. All parts are CNC machined of aluminum, coated with a durable black anodized finish and internally baffled to reduce reflections. The 1.25" barrel is threaded to accept standard 1.25" Eyepiece Filters. See our optional clear glass Dust Filter ( #T1FLT ), recommended to help keep dust out of your camera .

Included in this kit: Our fixed "Eyepiece Projection" adapter, a 1.25" "Prime Focus" adapter, a T-Ring to fit your brand of camera and a parfocalizing ring for easier high power focusing.

This kit is suitable for:
Prime Focus 96 In this imaging method the camera is connected directly to the telescope and placed at the "prime" focus of the telescope. The telescope becomes the camera lens. No eyepiece is used in this method. This method provides the widest possible field of view, the shortest possible exposure time and moderate magnification.

This Deluxe kit includes the parts you will need for both "Prime Focus" and Variable "Eyepiece Projection" astrophotography packaged together in one money saving, easy to purchase kit. The "Variable" feature lets you adjust the adapter length to vary the magnification (thus image size) for perfect framing of your shots. Fits telescopes with a standard 1.25" eyepiece port.

The upgraded VEPA Plus adapter can hold eyepieces up to 42mm in upper body diameter. It also features a laser engraved extension scale for recordability and repeatability as well as a large machined grip ring.. for a sure grip in even the worst dew conditions. CNC machined of aluminum with a durable black anodized finish. The 1.25" barrel is threaded to accept standard 1.25" Eyepiece Filters. See our optional clear glass Dust Filter (#T1FLT), recommended to help keep dust out of your camera.

Included in this kit: Our new premium VEPA Plus (Variable Eyepiece Projection Adapter), a 1.25" Prime Focus adapter, a T-Ring to fit your brand of camera and a parfocalizing ring for easier high power focusing. Includes a 5 page illustrated setup manual covering basic setup, troubleshooting and tips.

This kit is suitable for:
Prime Focus 96 In this imaging method the camera is connected directly to the telescope and placed at the "prime" focus of the telescope. The telescope becomes the camera lens. No eyepiece is used in this method. This method provides the widest possible field of view, the shortest possible exposure time and moderate magnification. Typically used for imaging nebulae, galaxies and other large (but dim) deep sky objects.

Eyepiece Projection & Variable Eyepiece Projection 96 In this imaging method an eyepiece is used to increase magnification. The eyepiece is placed between the camera and the telescope. The eyepiece 93projects94 the image onto the camera sensor. The projected image size increases with distance, similar to a flashlights beam. A "Variable" Projection adapter allows you to change the projection distance. This varies the magnification of the system, allowing you more flexibility when framing your shots. Think of it as a "Fine" magnification control. Whereas "Coarse" changes in magnification are made by changing eyepieces. Eyepiece Projection is typically used for Terrestrial, Lunar & Planetary imaging and any time higher magnification is needed to bring out detail.

IMPORTANT: Additional parts may be required to reach photographic focus with certain telescope types:
SCTs and Maks generally have enough focus range without any additional optical or physical extensions.
Reflector type telescopes will typically require the use of a Barlow Lens (#BAR1).
Refractor type telescopes will typically require the use of an Extension Tube (#EXT126).

NOTE: The Eyepiece upper barrel can be no larger than 42mm in diameter.
Please see our VariMax adapters for using even larger Eyepieces.

As the CCD chips in our DSLR cameras get larger it is ever more important to have an unobstructed light path to prevent vignetting. The manufacturers of high end scopes wisely put 2" eyepiece ports on them. Why then do we insist on putting a 1.5" bottleneck before your camera?

T-Rings have been around for decades, a legacy standard that is long outdated. They exist not because they are the best solution for imaging, but because they are the easiest solution for manufacturing. After all it's much easier to spin a standard thread on all adapters, regardless of telescope port size or camera brand. The T-Ring may be convenient but it is simply out of its league on a scope with a 2" eyepiece port.. especially with a camera that can take advantage of it.

Our True-2™ UltraWide Adapter is a true 2" prime focus adapter that takes you directly from the bayonet mount to a 2" barrel with as few wasted photons as possible, adding as much as 10mm more clear aperture over legacy adapters! The largest clear aperture of any adapter on the market. And it costs little more than a quality T-Ring and 2" T-adapter. Fully baffled to reduce reflections and threaded for 2" eyepiece filters. Available with or without a safety undercut on the barrel. Don't choke the photons out of your camera with an inferior adapter!

Q: What's an undercut?
A: An undercut is a machined groove around the 2" part of the barrel where the thumb screw (or compression ring) makes contact with the adapter. The groove is a safety retention device to help prevent accidents should your focuser thumbscrew be left a little loose. Loosening can also happen due to a temperature changes. Some people love them and others hate them, most all quality eyepieces have them. Generally either will work fine, it is more a matter of personal preference. If in doubt we recommend you go with the undercut, it just may save your camera from a nasty fall.

Q: I have a Meade (or Celestron) SCT telescope and would like to have the benefits of this adapter but my scope only accepts 1.25" eyepieces. Is there any way I can use this adapter?
A:
If your SCT is not already setup to accept 2" eyepieces and accessories you will need a 2" Rear Port Adapter, this item threads onto the large "SCT" thread on the rear cell of your scope and converts it to a standard 2" eyepiece port. The True-2 will slide directly into this port. Please see the setup diagram for details.

Q: I have a Meade (or Celestron) SCT telescope. Will this adapter thread directly on to the rear cell of my scope?
A:
The True-2 adapter will not thread directly onto the rear "SCT" thread. It has a 2" barrel just like a 2" eyepiece and inserts into a 2" eyepiece port. If your SCT is not setup to accept 2" eyepieces you will need a 2" Rear Port Adapter. This is actually better than if it threaded on to the scope directly as it allows you to very quickly and easily install and remove the camera during a session. It also gives you absolute freedom in positioning the camera radially for the best framing of your shot.

Q: Will this adapter fit my spotting scope (or microscope)?
A:
The True-2 adapter is for astronomical type telescopes equipped with 2" eyepiece ports only. It will not fit spotting scopes or microscopes.

Q: I have a Meade (or Celestron) SCT telescope and would like to have the benefits of this adapter but my scope only accepts 1.25" eyepieces. Is there any way I can use this adapter?
A:
If your SCT is not already setup to accept 2" eyepieces and accessories you will need a 2" Rear Port Adapter, this item threads onto the large thread on the rear cell of your scope and converts it to a standard 2" eyepiece port. The T-Minus adapter will slide directly into this port.

Q: I have a Meade (or Celestron) SCT telescope. Will this adapter thread directly on to the rear cell of my scope?
A:
This adapter will not thread directly onto the rear of an SCT scope, It has a 2" barrel just like a 2" eyepiece and inserts into a 2" eyepiece port. If your SCT is not setup to accept 2" eyepieces you will need a 2" Rear Port Adapter. This is actually better than if it threaded on to the scope directly as it allows you to very quickly and easily install and remove the camera during a session. It also gives you absolute freedom in positioning the camera radially for the best framing of your shot.

Q: Will this adapter work on my Refractor type telescope with 2" Focuser?
A:
Yes, but most refractor type telescopes require you to remove the diagonal and replace it with a slightly shorter extension tube to reach focus with a camera. Please see your telescope manual or our "Camera Adapter FAQ" page under the heading "Focusing Issues>Refractors" for further details.

Q: Will this adapter work on my Reflector/Newtonian/Dob type telescope with 2" Focuser?
A:
Yes, but many reflector type telescopes require you to install a Barlow Lens between the camera adapter and the focuser to reach focus with a camera. Please see your telescope manual or our "Camera Adapter FAQ" page under the heading "Focusing Issues> Reflectors" for further details.

Q: Will this adapter fit my spotting scope (or microscope)?
A:
This adapter is for astronomical type telescopes equipped with 2" eyepiece ports ONLY. It will not fit spotting scopes or microscopes. If you need help selecting the proper adapter just send us an email. Please include camera and scope models.
