Skymap Pro 9, written by astronomers, for astronomers. It can display the sky as seen from anywhere on Earth for any date. Most of the modern GOTO telescopes can be controlled from a PC with Sky Map Pro 9 software. SkyMap Pro can "talk" to a variety of different telescopes using a serial cable between the computer and the telescope or DSC (cables are not supplied with the program). This is done using plug-in "device drivers", making it easy to add support for new devices to the program. Drivers are supplied with the program to control most GOTO scopes.
When computer control is activated, a cross-hair cursor on the map marks the point in the sky at which the telescope is aimed. On devices which support "slewing" under computer control, the telescope can be aimed at any object simply by clicking the desired object on the SkyMap Pro map.
I’m selling version 8 and 9 as a package. $110 shipped, insurance extra.
Parks ALP 2" (Light Pollution) Filter
These ALP (Anti Light Pollution) filters utilize state-of-the-art multi-layer coating technology to selectively filter out the mercury vapor and sodium light pollution. These filters are of tremendous value in the city since they block man-made light, and in dark sky locations they block neutral oxygen transmission (natural sky glow). Threaded to fit eyepieces and camera adapters. New $139.95, I’ll sell this like new one for $95 shipped, insurance extra.
