A digital camera today can be used with a wide range of accessories. The most commonly used are the lens, filter, external flash and tripod. But there’s also one very useful accessory which not many people know of. This is the telescope.

When one hears about a digital camera and a telescope being used together, the first question that comes to mind is “How do you use a telescope with a camera or a camera with a telescope?” Some might also ask “Can these two work together?” The answer is yes, it’s possible to use these two together.

Photographers and those still learning the ropes of photography can actually use a telescope with their digital or 35mm optical camera. There’s a telescope attachment kit available today that can people engaged in wildlife and astro photography can use. The kit normally contains T-mount adapters, camera-specific adaptors, eyepieces and other accessory parts.

Buying a telescope kit would be a good idea for easy installation. Otherwise, you will have to determine the specifications for the right T-ring and T-thread for your camera and purchase them separately. With a kit, however, you will have all the pieces already available.

You can buy a kit from a camera or scope optics manufacturer. You may also search for companies that provide T-adapter kits. There are some manufacturers of mobile phones that also offer telescope attachment kits that can increase your camera’s zoom capability.

The most important step here that you should not forget is to find out the model number of your camera. In this way, you will know the right telescope to purchase.

The DSLR is considered a popular telescope camera. It utilizes an automatic mirror system and pentamirror. This system works by directing light from the lens through the viewfinder. The telescope is usually attached to the camera.

The T-ring is attached to the camera by removing the eyepiece and screwing it onto the threads. You also need to thread the T-adapter to the T-ring. This step will join the telescope to the camera after which you can already use it.

Before using the T-mount, it is important to clean its threads with a lens brush. You may also use a soft cloth to clean the threads. Cleaning them will ensure that they will screw properly with a tight seal.

Keep in mind that the telescope may replace the camera lens. This creates a telephoto lens with greater magnitude.

Another component that may be needed is the tele-extender. This is composed of two tubes, one of which fits into the other. The purpose of one of the tubes is to fit to the telescope while the other one is threaded to fit a T-ring. To put them together, the telescope visual back should be attached to the tele-extender inner sleeve which, in turn, should attach to the tele-extender outer sleeve. This outer sleeve should then be attached to the T-ring.

To use the telescope, it is necessary to have a tripod. This will lessen the vibration which is normal for high magnifications.

    normaly the camera shakes violently but are not noticed, until you magnefy it so always use hi speed shutter at all times so can be clear when you zoom in for closeups
