Ready For Astrophotography?

The rewards of capturing images from space are endless - so are the accessories and techniques for doing it! The Celestron CPC telescopes are an amazing tool for astrophotography. While we are not going into long detail of astrophotography technique, we will cover here what accessories are used for astrophotography with the CPC series telescopes. There are different methods of mating your particular camera to the CPC, or other choices of astrophotography tools you should know about:

DSLR Imaging - One of the fastest growing and most popular methods of astrophotography is using DSLR Cameras. The most popular digital SLR cameras are from Nikon and Canon. To connect a DSLR camera to your CPC telescope, you will need 2 pieces - A T-Adapter and a T-Ring.

The Celestron T-Adapter for Schmidt Cassegrains simply thread connects to the rear-cell of the CPC telescope. To connect your DSLR camera you will need to remove the lens from the camera, and replace it with a T-Ring. With the appropriate T-Ring attached to your DSLR camera you will then be able to connect your camera body directly to the T-Adapter connected to your CPC telescope.

We also recommend that you use a Celestron Reducer/Corrector. This Focal Reducer accessory will reduce your telescopes focal ratio. This focal reducer attaches first to the rear-cell of the CPC telescope, followed by the T-Adapter, then followed by your camera body with T-Ring attached.

CCD Imaging

Instead of using a CCD chip from a DSLR camera, there are also many CCD Cameras dedicated to astronomy.

Preventing Dew with the 11 Inch CPC Telescope

Dew forming on the lens of your telescope can quickly end an evening of observing. Once dew has formed, its very difficult to get rid of it. The answer is to prevent it from happening at all. Dew prevention can mean taking full advantage of those rare clear sky evenings or packing it in early.

There are two methods of preventing dew from forming. Dew Shields and Dew Heaters.

• Celestron Dew Shield - Simply wraps around the end of the telescopes optical tube, extending the tube out past the lens surface. This extra tube extension slows down the forming of dew substantially. It also blocks stray light from entering your telescope. In our opinion, a must have accessory.
• Dew Heater - A dew heater wraps around the aperture of the telescope near the optical surface, a small amount of heat is sent through this accessory making dew impossible to form. A dew heater must be powered by a dew controller to provide power. For more information, read our article on Dew Prevention here.
