Pentax 105 SDP - 4" f/6.4 APO Refractor OTA - Discontinued

Pentax 105 SDP - 4" f/6.4 APO Refractor



The Pentax 105 SDP APO refractor is now available in the US from Oceanside Photo & Telescope! This portable, well made telescope is crafted to extremely high standards, and performs beautifully when used visually or as a high quality astrograph



The 4-element, 2-group design of the Pentax 105 SDP was created to produce excellent image quality over the entire field of view. The front element in the first doublet is made of SD glass, and the front element in the second doublet (third element in the system) is crafted of ED glass. This configuration yields images of excellent contrast and detail, with great color correction, even at high magnifications. Special multi-coatings designed to increase the transmission of astronomical wave lengths are used on all Pentax APO telescopes, and the integrated corrector yields a flatness of field that is sure to please the most discerning imager!



When it comes to design features, the Pentax 105 SDP has what you're looking for. The drawtube has an inside diameter of 90mm, and fully illuminates 6 X 7 format with ease. The excellent focuser has 62mm of travel and is free of image shift. With a Visual Limiting Magnitude of 11.8 and a Resolution Power of 1.11 seconds, this is one dandy little scope!
