93588 Night Vision Flashlight by Celestron

A red flashlight is one of the most beneficial accessories you can own as an amateur astronomer, no matter how occasional your night sky observations may be. Also, if you plan to observe with other people, whether at a star party or in your own neighborhood, a red flashlight is an important part of good star party etiquette.

When you are outside doing astronomy, or any night-time activity that requires you to see as well as possible, any white light is a detriment. Every time you use white light, your eyes react. The pupils contract, making their aperture smaller, and a smaller aperture always means less light-gathering, whether we are talking about your eyes or your optical equipment.

A red flashlight allows you to see your star charts, find an eyepiece in your accessory case, or pick your way over telescope cables and other obstacles without affecting your night vision. The better your night vision, the more you can see in the eyepiece.

The Celestron Night Vision Flashlight uses two LED's to provide variable red illumination. Use the thumb wheel to adjust the light as you need it. The square shape of the flashlight keeps it from rolling off of your observing table to the ground. A lanyard is attached so you can wear it around your neck. The Night Vision Flashlight is powered by a 9V battery (included).

93419 T-Ring for Canon EOS Camera by Celestron

A T-Ring is one of the first accessories you will need if you want to take pictures through a telescope or spotting scope. If you have a Canon EOS camera body, the Celestron EOS T-Ring is the one for you.

To use the Canon EOS T-Ring, remove the lens from your camera, and attach the T-ring in its place, just as you would if you were mounting a lens. The telescope side of the t-ring has threads that will accept a variety of camera adapters, including the Celestron T-Adapter or Tele-Extender. The adapter you choose depends on the type of photography you wish to do.

You can take pictures of terrestrial and/or celestial scenes by using a simple T-Adapter to turn your telescope or spotting scope into a large telephoto lens. The #93633-A T-Adapter is the best choice if you own a Schmidt-Cassegrain telescope with standard rear cell threads. If you have a refractor, the Universal T-Adapter (#93625), with its 1-1/4" barrel insert, is available. There are also special T-Adapters for the EdgeHD optical system: one for the 8-inch EdgeHD (#93644) and one for the 9.25, 11, and 14-inch EdgeHD (#93646).

Prime focus photography is popular for short exposure images of terrestrial objects as well as celestial objects like the Moon.

If you need extra magnification beyond that which your Schmidt-Cassegrain telescope provides, a Tele-Extender (#93643) will allow you to insert an eyepiece inside the barrel before attaching it to the telescope. A Tele-Extender is used most often for high power images of the Moon and the planets.

• This Celestron T-Ring attaches to Canon EOS DSLR and SLR camera bodies.
• Sturdy bayonet flange locks in place just like a lens, providing secure contact.
• Attaches to a variety of camera adapters and accessories via standard T-threads.
• This T-ring fits EOS model cameras only. It will not work with other Canon camera bodies.
