Celestron CPC Deluxe 1100 EdgeHD Telescope

Combines the heavy duty fork arm with the new EdgeHD Optics

The largest aperture of the CPC Deluxe HD series, the CPC Deluxe 1100 HD telescope has the most light-gathering power; almost 90% more than the 8" model and over 40% more than the 9.25". And best of all, the CPC Deluxe 1100 HD combines Celestron's newly designed fork mount with its superior EdgeHD optical system. With sophisticated software features like the Hibernate function, the CPC can maintain its star alignment night after night without needing to be re-aligned, making it an ideal instrument for a permanent observatory facility. Even with an aperture of over 1500 times the light gathering power than the unaided eye, the CPC Deluxe Series is still one of Celestron's most portable astronomical telescopes. With its conveniently located carrying handles and an instrument weight of 66 lbs, this telescope is portable enough to setup in your backyard or take with you to your favorite dark sky location. The CPC Deluxe 1100 HD is at home as a superb visual instrument or with optional Pro Wedge and CCD cameras, as a serious astro imager's tool. Turn this scope to planets and see amazing detail on the surface of Jupiter; see Cassini's Division in the rings of Saturn, and resolve details on the surface of Mars and even distant globular clusters.

New Optical Design The EdgeHD optical system combines all the compact power popularized by the SCT with an improved high definition optical system for wide field, astrograph quality images. As a visual instrument, EdgeHD optics deliver pinpoint images, even with your widest field eyepiece. You can search for all of the Messier Catalog objects and see hundreds of other NGC, IC and Caldwell objects with amazing clarity. For astro imaging, EdgeHD optics produce aberration-free images across your favorite CCD or DSLR camera. All EdgeHD optics are designed to produce an extremely flat focal plane precise enough to match the strict tolerances of the largest commercial CCD detectors, allowing stars to be in tight focus to the very edge of the chip. Learn more about the benefits and features of this new optical system by going to the EdgeHD web page.

Internal GPS The 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 SkyAlign Once 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 the hand control to manually point (slew) the telescope to three bright celestial objects. You do not need to know the names of the stars and 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 Database The CPC Deluxe HD database contains over 40,000 celestial objects including Messier objects, the Caldwell Catalog, 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). 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.

Fastar Versatility All EdgeHD optical tubes are equipped with a removable secondary mirror for fast f/2 CCD imaging. Not only does imaging in the FASTAR configuration allow for exposure times that are 25 times faster than at f/10, but also yields a field of view five times wider. A perfect combination for imaging your favorite wide field objects in a fraction of the time. (FASTAR imaging requires a third party lens assembly in place of the secondary mirror).

Luminos Eyepiece CPC Deluxe 1100 HD comes with Celestron's top of the line, wide field eyepiece. With a 23 mm focal length and 82° AFOV, you get an incredible combination of power and wide field of view. Plus each Luminos eyepiece is optimized to deliver pin point images when used with a flat field telescope.

Innovative Features

Design - With the introduction of the CPC Deluxe HD series, Celestron has gone back to the drawing board and re-designed and re-engineered the drive train with a larger 6 inch, 180 tooth brass gear and .75" stainless steel worm gear and unique roller bearing design with both steel and nylon ball bearings rotating around a wide 9.8 track designed for smoother tracking accuracy for long exposure astro imaging.
Innovation - The CPC Deluxe HD series uses the innovative All-Star™ Polar alignment procedure. Coupled with Celestron's optional Pro Wedge, All-Star allows users to choose any bright star, while the software calculates and assists with polar alignment. Another great feature of the CPC sure to please astro imagers, is the Permanent Periodic Error Correction (PEC), which allows users to train out the worm gear's periodic errors, while the mount retains the PEC recordings.
Power Management - Redesigned electronics deliver constant regulated power to the motors making them capable of driving the telescope, even when not perfectly balanced, without sacrificing smooth tracking motion and pointing accuracy across the entire sky.
Performance - For objects near the meridian (imaginary line passing from North to South), the CPC will track continuously through the meridian for uninterrupted imaging through the most ideal part of the sky.

Zygo Interferometer Testing For ED Refractor Telescopes!

We are extremely pleased to announce our Zygo Interferometer is now installed and ready for use! Our experienced staff can test refractor lenses up to 120mm aperture and provide a comprehensive 2 page report showing the optical quality and Strehl ratio, plus much more information. We are using the very latest Zygo MX software to provide a more detailed report compared to other standard reports.

The interferometer is essentially a measuring instrument. Within the interferometer is a calibrated laser that is pointed through the optical test surface, then onto a high quality reference sphere, then back through the test subject then to an internal camera which gives us the measurement on the screen. From this, we can adjust the position of the test optic and the reference sphere to obtain a perfectly calibrated system. The more central the laser to the test optic and then on return, the better and more accurate reading and measurement we can take. This takes a lot of adjustment to get the best results from the optical surface. Once the measurement has been taken, we are provided with a series of results that show the optical quality of the surface plus other information. Continue reading for an explanation of the individual values and you can also see a test report that was done on one of our RVO Horizon 60 OTAs. 

We are offering certain telescopes with a Zygo test at an extra cost. Mainly ED doublets and triplets. All available telescopes with a Zygo test report are listed here. Just select Zygo Test Report from the drop down box at the top of the listing and we will test the optics in house and provide a full 2 page report with your scope. This will show you the optical quality of your telescope optics. We can also offer this service on your refractor telescope. Please get in touch for more details about this. 

At Rother Valley Optics, one thing we pride ourselves on is customer service and quality of our equipment. When we test your telescope, we will ensure that it is of the highest quality otherwise, we will reject the scope under our strict quality control and test another model for your peace of mind. One of the main values to look at when testing a refractor is the Strehl ratio. The higher this number, the higher quality lens you have. At Rother Valley Optics, we will guarantee the highest possible Strehl ratio for your telescope.  We will aim to provide 0.95 Strehl or higher on Takahashi, RVO Horizon, William Optics and many more! Generally, the higher the Strehl ratio, the lower the Astigmatism and Coma meaning a better image quality from your instrument. 

Other measurements such as the PV and RMS are important too. With these measurements, the lower the number the better as it shows less curvature on the lens. The flatter an optical lens, the better it will perform. The PV rating (Peak To Valley) is a measurement from the highest point (Peak) to the lowest point (Valley). From this we get the RMS (Root, Mean, Square). This is a similar figure to the PV and measured exactly the same way. The RMS is basically an average height difference from the PV so again, the lower the better. As you can see form the example below, we measured an RMS of just 0.027 wave which is a very good value.

We also measure the Power with our systems which is essentially the error from the reference sphere to the test optic. The reference sphere we use on our system is a very high quality sphere so the closer to zero the Power, the less error between the 2 elements thus ensuring a higher quality optical surface. 

You will also see some more values such as Astigmatism and Coma. Again, these are measured by the interferometer when we take measurements of the optical surface after adjustment. These are values which ideally would be at 0 but as our test optics are all curved lenses, there will always be astigmatism and coma present. The lower the number, the less of these aberations you will effectively see but with most refractors, you can buy field flatteners which will compensate for the coma anyway. The astigmatisms value is explaining the error between the symmetrical curvature of the lens. Basically, no lens will be perfectly symmetrical, the lower the astigmatism, the more symmetrical the lens surface is. 

Once the Zygo test report has been completed, the optical alignment is thoroughly tested and tuned to ensure they are spot on before they leave us. 

All available telescopes are on the website at the link below and ones we've tested already that are available straight away are also listed.
