Product description OCAL Electronic Collimator OCAL - New Generation Electronic Collimator The revolutionary way to collimate your instrument is with OCAL, the new smart device that allows you to collimate your Newtonian telescope via your computer in a simple, precise and fast way. The collimation of a reflecting telescope is a problem that astronomers must solve. OCAL electronic collimator is an electronic device developed by Chaoxing Astronomy to calibrate the collimation of reflective telescopes. Its main function is to mark several calibration circles through software to achieve the purpose of collimation. Difference between OCAL and OCAL PRO OCAL OCAL PRO Laptop Use (for Windows) Yes Yes Android/ iOS via OTG Adapter No Yes Newton Collimation Yes Yes SC Collimation No Yes RC Collimation No Yes (test mode) Main Features Each collimator has a very high level of pixel accuracy, thanks to OCAL high quality control. The installation takes place via T2 thread (M42x0.75) to minimize the installation errors. Collimation errors that are often caused by human different visual axis can be completely eliminated with OCAL technology. The product solves the problem of collimation even on large telescopes, thanks to the collimation assistance feature the result is shown immediately on the screen. Quick and easy: Collimate your instrument in just 4 steps! The product can check if the center mark on the primary mirror is made correctly or not. You can also use the screenshot feature to save the result of the collimation. Scope of Delivery: Collimator cable Tips and tricks: If the screen goes black after a few seconds in the Android version. Place your finger on the app icon. Select App Info. In the sub-item Other authorisation, tick the box for Display on lock screen. If the Windows version cannot be installed on your computer, please install the corresponding software from the OCAL download folder. This is called VC_redist.xt.x64 or VC_reddist.x86.

Explore Scientific 82° Series™ extreme wide field eyepieces are optimized to produce high contrast, high resolution, and superior flat field characteristics. The visual effect of these eyepieces with their long eye-relief and their 82° apparent field is truly a full-immersion experience. Your eye is relaxed, allowing you to easily use the "averted vision" technique to study faint details across a huge field-of-view. The 82° Series eyepieces come with a twist-up rubber eye-guard that raise to the desired height for the comfort of the observer, and as experienced astronomers know, eye comfort is critical when trying to observe at the visual limits of the telescope. To keep internal reflections to a minimum, all internal surfaces of the eyepiece barrel are flat black, as well as the edges of the lenses themselves to minimize the scattering of light within the lenses themselves. All 82° Series eyepieces are fully multi-coated and edge-blackened to produce maximum contrast.
