How to Use a Front Surface Mirror as a Binocular Mount

 

Until the inception of the front surface mirror, or first surface mirror as it is also called, most aspiring astronomers resorted to using binoculars to view celestial objects in the night sky. Those with an interest in astronomy still use binoculars however the addition of the front surface mirror has added a new twist on traditional binoculars which makes a great view of the night sky more user-friendly and appealing.

First, let’s define what a front surface mirror is in the event the term is new to you. Front surface mirrors are used for scientific instruments, military simulation equipment, astronomy units, and space exploration equipment. There are two different types of materials that front surface mirrors are made of which include acrylic and glass. Acrylic front surface mirrors are less expensive to manufacture and are generally used for hobbies and general projects. Front surface mirrors made of glass are more expensive and are used for high end scientific equipment.


Using a Binocular Mount with a Front Surface Mirror

 

A lot of aspiring astronomers have constructed tripods with which to mount the binoculars to help make viewing the night sky more enjoyable and user-friendly. While this proved to be a more efficient way to view celestial objects recently an amateur astronomer came up with a new way to use binoculars for viewing the night sky. The invention looks like a deceivingly simple device while providing a solution for a new and improved viewing experience.

The device consists of an aluminum tripod with a frame attached to it that holds the front surface mirror. A mount on the top of the frame holds the binoculars securely in place. The user can look down through the binoculars which are pointed at the front surface mirror and observe the sky in a seated position. The device which is referred to as a Sky Window can be used with a tripod or you can easily position it on a table for easy viewing. Some astronomers that find the design so simple choose to build their own binocular mount with a front surface mirror.

Constructing and Using a Front Surface Mirror with Binocular Mount

 

If you choose to construct your own device to use for viewing the night sky this can easily be accomplished with a 1 x2 main beam of wood with a mount for securing the binoculars. The front surface mirror is attached to a plywood platform and secured through a silicone adhesive. For best results, you can place nails beneath the front surface mirror before placing it down light on the silicone glue. This allows the front surface mirror to expand and contract. Once the glue has dried, you can simply remove the nails which allow the front surface mirror to basically float without actually touching the plywood surface.

The platform is then secured to the beam before the entire unit is attached to the tripod and to a pan and tilt head that allows you to manipulate the binoculars and mirror to scan different parts of the night sky.

To use this type of device with a front surface mirror and binocular mount it is necessary to experiment with different types of binoculars. Certain makes of binoculars will provide you with a clearer view of the night sky than other brands of binoculars. For example, if you are having trouble getting a clear view with 16x binoculars another type may work better such as 7 x 50. If you have a first rate front surface mirror installed on the unit and have trouble getting a clear view, it is most likely the type of binoculars that you are using so the object of the game is to experiment until you get the results you are seeking.

If you do some research you will find a host of creative ways that people have come up with to use a front surface mirror with a binocular mount. All of these creations are take offs on the Sky Window, a very simple concept developed by an amateur astronomer. As long as you have the proper materials you can experiment with the unit you have built until you find a combination that works for your needs.
