The following is a partial list of optional accessories available for your Celestron CM-1100/1400. You will find that additional accessories enhance your viewing pleasure and expand the usefulness of your telescope. For ease of reference, all the accessories are listed in alphabetical order.
AC Adapter - 110V - 60Hz (#18770) - The AC Adapter allows you to run your CM telescope off of AC rather than the standard DC battery.
Advanced Astro Master (#93900) - This unique accessory contains a data base of more than 10,000 objects! Included are the Messier catalog, NGC catalog, IC catalog, portions of the ESO catalog, portions of the UGC catalog, special non-stellar catalog which contains objects not found in any of the other catalogs, a star catalog containing 241 interesting double and multiple stars, and a user definable catalog that allows you to enter 25 of your favorite objects. And, scrolling information cross references Sky Atlas 2000.0 or Uranometria . Unlike other digital setting circles, which require the use of a clock drive, the Advanced Astro Master can be used with or without a clock drive. All you have to do is align on any two of the 28 navigational alignment stars in the Advanced Astro Master’s data base and you are ready to observe. Once aligned, the system keeps track of where it is pointed. And, the Advanced Astro Master has an RS-232 port for complete interface to your personal computer. The RS- 232 cable (#93921) is available. The encoder installation kit for the CI-700 mount is #93908.
Barlow Lenses - A Barlow lens is a negative lens that increases the focal length of a telescope. Used with any eyepiece, it doubles the magnification of that eyepiece. Celestron offers two Barlow lenses in the 1-1/4" size. The 2x Ultima Barlow (#93506) is a compact triplet design that is fully multicoated for maximum light transmission and parfocal when used with the Ultima eye- pieces. It works very well with all Celestron eyepieces. The latest Barlow to be added to Celestron’s product line (#93507) is a low profile achromatic design. It weighs just 4 oz. and it is under 3" in length.
Counterweight - 11 lbs. - Extra counterweights (#94195) may be necessary when using heavy accessories.
2” Mirror Diagonal (#93519) -For the CM-1100 (Standard on CM-1400). Like the l-l/4" Prism Star Diagonals, the 2" Mirror Diagonal allows you to use 2" eyepieces with your Celestron telescope. These larger eyepieces offer wider fields and better eye relief for greater viewing comfort. This accessory is NOT recommended for use with the Reducer/Corrector Lens.
Erect Image Diagonal (#94112-A)- For daytime terrestrial viewing the Erect Image Diagonal produces images through your Schmidt-Cassegrain telescope that match what you see with the unaided eye. This accessory uses an Amici
