APT User's Guide User's Guide APT v3.88 Incanus Ltd © 2009-2021 Distinct Solutions Ltd. © 2017-2021 www.astrophotography.app APT stands for "AstroPhotography Tool" and it is like Swiss army knife for your astro imaging sessions. No matter what are imaging with - Canon EOS, Nikon, CCD or CMOS astro camera, APT has the right tool for planning, collimating, aligning, focusing, framing, controlling, imaging, synchronizing, scheduling, meridian flipping, analyzing and monitoring. All its features are packed in an easy and comfortable to use interface with design that had no alternative back in 2009 when it was released. Since then APT is constantly being improved and refined by the real experience of many astro photographers from all over the world including one of the APT authors. Currently APT works on MS Windows XP, Vista, 7, 8, 8.1 and 10. APT has time unlimited "demo" version with almost all features of the full one. In fact this "demo" is one of the most loaded astro applications available for free. If you like APT you can support the future development with a small fee! About this document The approach to this document is minimalistic. A description of all features in APT and the related information in the short and easy to use form. The two main sections are Application Interface and APT Features. In the first one you can find explanation 1 for everything you see in APT. The second one is a kind of index of the main APT functions. There are few more sections that are focused on important areas like Dithering, PointCraft and SessionCraft. This guide is designed to use the full power of the hyper-links and to give possibility to track easily all the linked information without text duplication. In the same time is used common naming of the sections in order to make easier for reading if one decide to print it (PDF version here). The User's Guide is not book in its classic form and there is no proper or right way to read it :) You can read it page-by-page or in random order. Every topic contains a focused information and links to all related topics. Special tanks to Dennys Turcotte for his work to make this document better and more clear to read! Support APT has a dedicated forum - www.aptforum.com. It is a place where you can ask or search specific questions. Also it is a growing source of information related to astro-photography in all of its aspects - imaging, automation, processing and etc. It is the preferred way to discuss everything around APT because your questions, answers, suggestions or ideas can be in help to others. The registration is more than easy! There is also a group in Facebook - APT Group. It is mainly focused on sharing news and images taken with APT. You can find help there too, but because of the Facebook nature it is harder to find previously asked questions... If you prefer or need more private communication then you can use [email protected]. All feedback, suggestions and ideas are highly appreciated!

STOP!!! Read the Instruction BEFORE setting up and using the mount! Worm/gear system damage due to improperly use will not be covered by warranty. Questions? Contact us at [email protected] Instruction for CEM120 Gear Switch and Axle Locking Knob Both RA and DEC have the same Gear Switch and Axle Locking Knob, the operations are the same. Gear Switch Axle Locking Knob As an example, here are the positions for the Gear Switch and Axle Locking Knob for RA axis: Fig.1: When transferring or installing the mount, lock the Axle Locking Knob and disengage the Gear Switch . So the RA won’t swing and there is no force applied onto the worm/ring gear. Fig.2: During mount balancing process, pull and turn the Axle Locking Knob to release it and leave the Gear Switch at disengaged position . Now the mount will swing freely in RA direction.

  • Making Your Own Astronomical Camera by Susan Kern and Don Mccarthy
    www.astrosociety.org/uitc No. 50 - Spring 2000 © 2000, Astronomical Society of the Pacific, 390 Ashton Avenue, San Francisco, CA 94112. Making Your Own Astronomical Camera by Susan Kern and Don McCarthy An Education in Optics Dissect & Modify the Camera Loading the Film Turning the Camera Skyward Tracking the Sky Astronomy Camp for All Ages For More Information People are fascinated by the night sky. By patiently watching, one can observe many astronomical and atmospheric phenomena, yet the permanent recording of such phenomena usually belongs to serious amateur astronomers using moderately expensive, 35-mm cameras and to scientists using modern telescopic equipment. At the University of Arizona's Astronomy Camps, we dissect, modify, and reload disposed "One- Time Use" cameras to allow students to study engineering principles and to photograph the night sky. Elementary school students from Silverwood School in Washington state work with their modified One-Time Use cameras during Astronomy Camp. Photo courtesy of the authors. Today's disposable cameras are a marvel of technology, wonderfully suited to a variety of educational activities. Discarded plastic cameras are free from camera stores. Students from junior high through graduate school can benefit from analyzing the cameras' optics, mechanisms, electronics, light sources, manufacturing techniques, and economics. Some of these educational features were recently described by Gene Byrd and Mark Graham in their article in the Physics Teacher, "Camera and Telescope Free-for-All!" (1999, vol. 37, p. 547). Here we elaborate on the cameras' optical properties and show how to modify and reload one for astrophotography. An Education in Optics The "One-Time Use" cameras contain at least six interesting optical components.
