Celestron CPC Telescopes are available in three aperture size choices:8 Inch CPC Schmidt-Cassegrain Telescope9.25 Inch CPC Schmidt-Cassegrain Telescope11 Inch CPC Schmidt-Cassegrain TelescopeCelestron's new CPC Series with revolutionary SkyAlign AlignmentTechnology re-defines everything that amateur astronomers are looking for — quick and simple alignment GPS unsurpassed optical quality ease of set-up and use ergonomics enhanced computerization and most important affordability.

Internal GPSThe CPC Series' internal GPS receiver automatically downloads the date and time from orbiting satellites and pinpoints its exact location on Earth. This eliminates the need for you to manually enter the date time longitude and latitude.

Celestron's Revolutionary SkyAlignOnce the CPC's internal GPS has established the telescope's position aligning the telescope is as easy as 1-2-3! Simply locate and use hand control to manually point (slew) the telescope to three bright celestial objects. You do not need to know the names of the stars — you may even pick the moon or bright planets! Celestron's NexStar software technology will model the night sky to determine the position of every star planet and celestial object above the horizon. Once aligned the remote hand control allows direct access to each of the celestial catalogs in its user-friendly database.

Celestial Object DatabaseThe CPC database contains over 40000 celestial objects including Messier objects the Caldwell Catalog as well as NGC Galaxies nebulae and planets. User-definable filter limits make navigating through this expansive database quicker and easier. Filter Limits let you filter out objects that are outside of your local horizon (ie if trees or mountains were in the way). Identify feature tells you what you're looking at but it can also be a very fun way to tour around the sky. Just point the telescope up somewhere and ask it to identify Messier objects (for instance) and it will show you the 5 nearest Messier objects to your position and let you GOTO them. You can keep doing this for different parts of the sky or for different object types -- it is a lot of fun.

There's also Solar Sys Align that lets you align on the sun or moon for daytime observing -- it is easy to use this to see planets or bright stars in the day.

The CPC series telescopes do not take batteries. Won't take batteries! What! Actually this is a good thing. These larger telescopes eat through batteries pretty quickly. Its best to have a more reliable power source. You can also purchase an AC adapter Accessory if you will be using the telescope within reach of an AC power outlet. We highly recommend the use of the Celestron PowerTank accessory. This is a great accessory for powering your CPC telescope with the included DC adapter. A Celestron PowerTank is great for traveling to darker sky locations. Astrophotography with the Celestron CPC TelescopesWhile astrophotography could not be summed up here in one paragraph a very common question for the CPC telescopes is how to connect a camera to it. Astrophotography is a hobby of patience and lots of trial and error and plenty of errors will be had once you get started. But the rewards of good images is well worth it. Let's start first with connecting a DSLR camera - as these have become so popular over the last few years. I will use the example of connecting a Canon EOS Digital SLR Camera. First you will need a T-Adapter for a Schmidt Cassegrain telescope. This will thread onto the back of your Celestron CPC telescope. Next you will need an appropriate T-Ring for your camera. For a Canon EOS you would use the T-Ring for Canon EOS Cameras. You will remove the lens from your camera and replace it with this T-Ring. Now you will be able to thread the camera to the back of the telescope. This is an easy way to begin astrophotography with your CPC telescope. We would however highly recommend also getting the Celestron Focal Reducer as this will dramatically help with shortening exposure times and help you get better results faster. Available Recommended Accessories The Celestron CPC Telescopes have many enhancement accessories available. A few of our staff user favorites include: Celestron Eyepiece and Filter Kit - 1.25 Inch Format The 8 Inch CPC Telescope includes a 40mm Plossl Eyepiece. The 8 Inch CPC focal length is 2032mm so this included eyepiece will yield you 51x magnification. To get the most from your new CPC Telescope we recommend you have a wide selection of eyepieces for high power viewing as well as wide-field viewing. The Celestron Eyepiece and Filter Kit - 1.25 Inch Format will give you that wide selection of eyepieces. This kit includes five 1.25 inch format eyepieces to give you the following magnification ranges in the 2032mm focal length 8 inch CPC Telescope: 4mm (508x Magnification)6mm (339x Magnification)9mm (226x Magnification)15mm (135x Magnification)32mm (64x Magnification)This wider array of eyepieces will enhance your viewing of lunar and planetary surfaces. Select the Celestron Eyepiece and Filter Kit - 1.25 Inch Format as a great starter accessory for getting the most of your new Celestron 8 Inch CPC Telescope. Upgrade to a 2 Inch Diagonal and 2 Inch format Eyepieces 2 Inch Format Eyepieces will deliver a wider field of view. Instead of only having the Andromeda Galaxy in your field of view now you can also have the same view but with its surroundings. A 2-Inch format eyepiece also gives the feeling of spacewalking into the view. Your eyes see substantially more field of view and many find that the 2 inch format eyepieces are more comfortable to view into. Before you can use a 2 inch format eyepiece on the 8 inch CPC telescope you must upgrade the 1.25 inch format diagonal that is included with the telescope. By changing to a larger 2 inch format diagonal you are now able to use 2 inch format eyepieces. Most 2 inch format diagonals also include a reducer adapter that will continue to allow you to use your 1.25 inch format eyepieces Here are some choices of upgrades to change your 8 Inch CPC Telescope to use 2 Inch Format Eyepieces: Good - Celestron 2 Inch Diagonal MirrorBetter - Celestron 2 Inch Diagonal Mirror with StarBright XLT CoatingsBest - William Optics 2 Inch Carbon Fiber Dielectric DiagonalOne of our favorite options for upgrading the Celestron 8 inch CPC Telescope to use 2 Inch format eyepieces is the Celestron 2 Inch Eyepiece and Filter Kit This Kit comes complete with a 2 Inch Diagonal 2X Barlow Lens Three 2 Inch Format Eyepieces 2x Barlow Lens and five 2 Inch Format filters. This is a great kit for upgrading your CPC telescope. Upgraded Diagonal now select some premium 2 inch format eyepieces Its common to hear that your telescope is only as good as your eyepiece. The eyepiece is how you deliver the image your telescope has gathered to your eye. A quality eyepiece can mean the difference of seeing major amounts of detail.

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 8 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.
