The Celestron Rowe-Ackermann Schmidt 11" astrograph, is the telescope designed by Celestron dedicated to astrophotography. With this instrument is not possible to make visual observations, but its incredible focal length f/2.2, together with the large telescope diameter, allows deep-sky object astrophotography even with short exposure times. If you are looking for a dedicated instrument to deep-sky photography, this is the ideal solution. Thanks to appropriate adapters supplied, the imaging camera is installed in front of the telescope, instead of the secondary mirror. The Celestron Rowe-Ackermann Schmidt 11" astrograph is designed for the more demanding astroimagers. 3 years of warranty on the optical tube!

In the picture above, Celestron Rowe-Ackermann Schmidt 8" astrograph with SESTO SENSO and the following optional accessories: 495mm PLUS Losmandy type bar (above the OTA) with thee EAGLE installed in parallel (above the telescope).
The autoguide with this astrograph in many cases it is not necessary (a precise polar alignment of the mount is often sufficient), the short focal ratio and its large diameter, making it bright and fast. The useful optical window is 43mm, it's geometrically and chromatic well corrected, perfect for imaging with DSLR or CCD cameras even with large sensors. The housing of the camera with the relative adapters (supplied as standard) allows to use any type of sensor, DSLR or CCD. In order to install the filters, an adapter ring is provided, to be screwed before the camera. This astrograph is equipped with a high-quality focusing system. The micrometric focuser Feather Touch is one of the best on the market, it's installed as standard on all Rowe-Ackermann telescopes in order to provide the user a high-quality tool not only optically but also mechanical. Since the large size of the mirror, a 12v powered fan is installed to speed up the optics acclimatization.
