James Edwards has written a review of the Takahashi CN212 / 8.35" Cassegrain / Corrected Newtonian. You can read the review at the IceInSpace Equipment Reviews page, or directly by clicking on the link below: Takahashi CN212 / 8.35" Cassegrain / Corrected Newtonian Thanks to James for writing the review. This is a special scope two in one you can switch from the 820mm Focal length Newton to the 2630 Cassegrain very easily. The mount is very sturdy and not to heavy. Stars are pinpoint in a very good night Jovian galilean satellites are obvious disks. Optical tube is light and easy to transport you can use the very good finder like a handle. The telescope is a 200 mm f/4 Newton (Takahashi CN212). The camera is an Atik460EX used at its full spatial resolution (binning 1x1, 4.54 microns pixel size). A method for calibrate Alpy 600 without the calibration module is also described in this tutorial (section 4). I use a Tak CN212 in the Cassegrain mode (the Newtonian mode I use at dark sky locations). The Cassegrain focal length of 2630mm provides a nice image scale. My mount is an alt/az Heavy Duty Binoscope mount with custom parts to insure stability. Field of View Calculator Test different telescope, camera & eyepiece combinations.

It can be a Cassegrain telescope at f/12.4 (or f/9.9 with focal reducer) for high resolution planetary work or a fast (f/3.9) Newtonian for wide field photography.
