Telescope/Mount Drivers

ACL Telescope Controllers (6.0.1)
DownloadInstalls a driver for telescope control systems that speak the Merlin Controls Astronomy Command Language. Please note that there is a specific driver for the COMSOFT PC-TCS control system below. Version 6.0.1 corrects a COM port setup bug, and has sources for building under Platform 6.
Ascom 2X Mount Adaptor (Paramount, etc., 6.0) for TheSky X and TheSky 5/6 (external link)

This is supplied by Software Bisque and is available from the Downloads section of the Software Bisque site, the file is called Ascom 2X Mount Adaptor Setup.exe

Installs a driver that connects to Software Bisque's TheSky X/6/5 Astronomy Software and makes it look like a standard ASCOM telescope. This allows ASCOM-based astronomy software to use TheSky (including TPOINT and ProTrack) as a smart telescope controller. For more information see Working with TheSky (section 1). It is required for the Paramount mounts, and may be used with TheSky controlling any other of its supported telescope types, or via its built-in outbound ASCOM support, and then using ASCOM telescope drivers. This driver provides Telescope V3 support, 100% conformance, and compatibility with TheSky X (10.2.0 or later). It should also work with TheSky6 and TheSky5 but not all functionality will be present.

Astro-Physics GTO - Factory Supplied Driver and Software
DownloadThis is the installer for the Astro-Physics factory-supported driver for all Astro-Physics telescope models. Please go to the Astro-Physics Driver web page for their driver and associated software.
Celestron Unified (6.0.5604)

Driver name (users, in the Chooser): Celestron Telescope Driver
ProgId (programmers only): ASCOM.Celestron.Telescope

New driver, written in C#. Note the new name and ProgId. Installs a driver for all computerized Celestron telescopes. This version has passed the Conformance Checker tests and has support for programmably changing pier side. It also recognises the StarSense HC. Park and Unpark use the mount Hibernate/Wakeup commands for NexStar+ HCs version 5.24. Works for locales where the comma is the decimal separator. See the help file, installed as part of the driver, for a full description.

This driver does NOT support Synta mounts.

Digital Setting Circles (David Ek, external link)
DownloadThis ASCOM driver allows the use of a variety of commercial and homebrew passive encoder-based digital setting circles systems with any Windows software that supports the ASCOM standard. This driver works with either alt-az mounts (like a dobsonian) or equatorial mounts. Equatorial mounts do not need to be accurately polar-aligned (although an accurate polar alignment will likely lead to a more satisfying observing experience). The button leads to David's web site for this driver as well as other info on DSCs.
EQMOD Project (external link)
DownloadWith the EQMOD ASCOM driver, the user will be able to control the Modded EQ mount using any ASCOM based astronomy software at 0.144 arcsecond resolution. This is an ongoing project, so be sure to check the site for updates.
Gemini Telescope .NET (1.0.62, Oct 2015)
DownloadInstalls a driver for mounts controlled by René Görlich's Gemini Astronomical Telescope Positioning System. Current firmware required!
Generic LX-200 (5.0.1)
DownloadInstalls a driver that uses a small subset of the LX-200 protocol. Features are limited, and end-of-slew detection may be unreliable (requires adjustment of encoder resolution). Use this driver with mounts that purport to use the LX-200 protocol. Be prepared for limitations and problems. Simple applications (such as planetarium slewing) are more likely to work than demanding automation applications.
iOptron CEM60 and iEQ45 Pro
DownloadInstalls a driver for the iOptron CEM60 and iEQ45 Pro mounts. This driver has been supplied by the manufacturer and has passed all conformance tests (report here).
LittleFoot Controller (1.0.0)
DownloadDriver for the LittleFoot Controller Project, specifically the LittleFoot Classic. For more info see Astronomie & Elektronik (a German/English forum).
Meade Universal Driver Project (June 2014)
DownloadLink to a driver that recognizes new Meade telescopes (LX850 and LX600), some earlier LX200GPS telescopes, and telescopes that recognize basic Meade Commands (e.g., LX200 Classic, Centurion). Provides position readout, slews, side of pier (where appropriate), and pulse guiding among its basic capabilities. It has passed Conformance Checking for the LX850 and the LX600 and has been run with a number of other Meade telescopes. While not complete functionality (e.g., missing tracking control, focus control, slew rate selection), this is the first iteration of a driver that is intended provide replacement capabilities for all existing Meade drivers. Please Note: This driver reports that it cannot control tracking (on/off) so it may not be suitable for automation applications.
Meade LX200 Classic and Autostar #494, #495, and #497 (combined telescope/focuser, 5.0.4)
DownloadInstalls a driver for the original Meade LX200 ("classic") telescope mounts (including the 16"), as well as Meade telescopes that use the Autostar I (#494, #495 and #497) controllers, such as the ETX and DS series. This driver provides both telescope and focuser interfaces each of which may be used by separate programs. Do not use this with the LX200GPS, LX200R or the RCX400. V5.0.4 corrects installer and driver version mismatches only, no logic in the driver has changed since 2008.
Meade LX200GPS and LX200R (combined telescope/focuser, 5.0.0)
DownloadInstalls a driver for the Meade LX200GPS and LX200R telescope mounts. This driver provides both telescope and focuser interfaces each of which may be used by separate programs. Do not use this with the LX200 Classic or the Autostar I (#495/#497) controllers. It has been reported that this driver also works with the RCX400 except it doesn't allow access to its unique features.
Meade MaxMount (1.0.0, March 2012)
DownloadInstalls a driver for the Meade MaxMount and MAX 20" ACF telescope mount.
PC-TCS (combined telescope/focuser/dome 5.0.1)
DownloadInstalls a driver for the COMSOFT PC-TCS telescope control systems. This driver provides combined telescope, focuser, and dome interfaces each of which may be used by separate programs.
ServoCAT (5.2.1, external link)
DownloadDriver for the StellarCAT ServoCAT telescope control system. Latest firmware is recommended but will run with old firmware (backwards compatible) with reduced features. The author provides a self-contained installer.
Sky Commander (2.1.0, external link)
DownloadDriver for the Sky Commander digital setting circle (DSC) device. The author provides a self-contained installer.
Takahashi Temma (5.0.26, external link)
DownloadDriver for the Takahashi Temma mounts. This is a full-featured driver that provides not only ASCOM standard driver functions, but also user access to many of the Temma's special features.
Vixen SkySensor 2000 (6.1.7)
DownloadInstalls a driver for the Vixen SkySensor 2000 telescope control system. This version corrects the installer so it can be installed on Platform 5 and 6 (and later). The driver has also passed the Conformance Checker tests (see this report).
Vixen Sphinx (external link)
DownloadDriver for the Vixen Sphinx mounts.
