Connect A to B
By far the most common type of adapter we make is that elusive piece to connect device A to device B. Chances are we have made that adapter before and we know precisely the kind of thread or dovetail needed for each end. Even if we have not made that exact one, we probably have the required specifications on file in our comprehensive knowledge base. Our automated online Build-An-Adapter can help you create and order the needed part in a few clicks, but if your device is not listed let us know. We will gladly add the device in our database if its specifications are available.

Special Adapters for Astrophotography
Do you need a T-threaded ring to setup your digital camera on the telescope? A specially machined adapter to rigidly mount a heavy CCD camera on the draw tube or the reducer/flattener at a precise optical distance? An Eyepiece Projection extender to insert an eyepiece in front of the camera? An afocal adapter to secure your camera to the eyepiece? We can make any of the above, for standard sizes and threads and for unusual ones as well. Our automated Build-An-Adapter can create the part in an instant.

SLR lens adapter for CCD or video camera
Many astronomical CCD cameras have a lens attachment allowing wide-field sky photography by piggybacking the camera on a telescope mount, but some cameras either do not have a lens adapter available or do not have the right model. We can create replicas of most lens mounts to fit your favorite SLR lens to a video or astrophotographic camera. A variety of lens types are listed in our Online Adapter Builder to design lens adapters for most astronomical cameras.
Note: For daylight pictures an infra-red filter is required for most cameras unless the CCD is equipped with an integral filter.

Solar Filters Adapters for Telescope Objective
Our online Build-An-Adapter can design adapters to allow installing a solar filter on selected objective cells. For safety and look, and to minimize cost we recommend mounting a solar filter using the thread available in many objective cells. If the objective has no thread, it may still be possible to design an adapter but expect the cost to be substantially higher.

Focuser Extension tubes
Do you need a focuser extension tube to allow a new accessory to reach focus or to locate a camera at the exact distance required by the reducer/flattener? We can make a drawtube extension with the same diameter, thread and finish as your drawtube, for standard sizes as well as uncommon ones.
Build-An-Adapter will most likely know how to create the part. Just select the generic-caps-extensions category on either side.

Camera Adapters with custom threads
Commercial adapters (T-Rings) are not always available for older SLR cameras, and for most viewfinder type cameras. We can machine threads with almost any pitch and adapt camera or lens bayonets to a telescope focuser tube or eyepiece holder. Our automated Adapter Builder can do that with little effort.

Adapters for commercial video cameras or webcams
Install a video camera in Prime Focus or in Afocal mode on your telescope. A number of inexpensive webcams or video chat cameras are available on the market. Although most of these cameras are not designed for use on a telescope, many have the capability. All that is needed is an accurately machined, nosepiece, flange, or T-Ring. Our automated Build-An-Adapter can probably make one of these in a few clicks or taps.

Eyepiece Extenders or Reducers
How many times did you have trouble reaching focus with a new eyepiece on the old scope, or conversely, a favorite eyepiece that couldn't reach focus on a new scope? The situation may be easily resolved with a properly sized adapter easily created with Adapter Builder.

Focuser Replacement
Are you dissatisfied with the focuser on your refractor or Newtonian? Would you like to replace it for one of these smooth Crayford, shiny black, beautifully machined mechanism? Build-An-Adapter can create an adapter plate to install one of a number of focuser models on selected telescope OTAs, with a design and finish blending seamlessly with the equipment selected (the focuser itself must be purchased separately).

Replacement Parts for Antiques and Vintage Instruments
Do you own an antique microscope or a vintage telescope that is missing a piece or needs some TLC? We can replicate many type of brass parts based on a broken piece or a picture of the original. The result will make your instrument look whole again. The intention is not to fool the expert but to restore the original appearance of a beautiful, and perhaps irreplaceable, instrument.
