NexRemote comes with a pair of add-on programs, NexGPS and NexTour, that add features the real HC cannot claim. NexGPS allows you to use any NMEA serial output-capable GPS receiver with your telescope. That means you do not have to spring for a fancy and expensive Celestron GPS add-on if your scope/mount didn’t come with GPS. Portable Capture Pro Software - Mac and Windows Versions.

Nexremote Mac Os X
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
This 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.AstroShop Omegon EQ500X Equatorial Mounts
This is the installer for the Omegon Mount EQ-500X sold by Astroshop.eu. Omegon mounts are a collection of Alt-Az and Equatorial mounts for visual observation and astrophotography. The Conformance report is part of the release. The mounts and driver pass with two errors related to coordinates granularity (1 arcsec minimum).Celestron Unified (6.1.7350, Feb 2020) Telescope & Focuser
Installs a driver for all computerized Celestron telescopes, now including the new Celestron Focuser. NOTE: Focuser moves are prevented if the focuser is not calibrated. Calibrate the Focuser before anything else! Also this driver does its best to compensate for the extra time needed for final approach in slews but which is not reported via the Celestron controller. This driver has passed the Conformance Checker tests. See the help file and release notes(!), installed as part of the driver, for a full description.
This driver does NOT support Synta mounts. Use the Sky-Watcher drivers listed below.
Digital Setting Circles (David Ek, external link)
This 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. 
Explore Scientific PMC-Eight Mount Controller Driver
This is the link for the PMC-Eight Mount Controller to download the PMC-Eight Software Development Kit.

Installs a driver for mounts controlled by René Görlich's Gemini Astronomical Telescope Positioning System. This latest version (2020) addresses compatibility with ASCOM Alpaca and also makes some needed changes for soon to be released firmware (stay tuned for this upcoming firmware release). Current firmware required!Generic LX-200 (5.0.1)
Installs 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. GS Server (July 2020) for Sky-Watcher and Orion Mounts
This is a server with its own graphical interface that provides an ASCOM Telescope interface as well as a Synta Protocol for Sky-Watcher and Orion mounts: EQ8, EQ8-R, HDX110, AZ-EQ5GT, Sirius Pro AZ/EQ-G, AZ-EQ6GT, Orion Atlas Pro AZ/EQ-G, EQ6-R PRO, NEQ6, HEQ5, EQ5, EQ4, AzGTi. iOptron CEM60 and iEQ45 Pro

Link to a new 'Meade Generic' driver for the Meade Autostar/Audiostar controlled Meade telescopes. This driver project is listed in hopes that the author can get feedback and work out any remaining issues. This driver has been created after discovering that the 'Meade LX200 Classic and Autostar #494, #495, and #497 (combined telescope/focuser, 5.0.4)' driver listed below does not implement enough features to allow the telescope to be properly operated remotely.The driver can be installed alongside any other driver (including the 'universal' one listed below). See the driver project website for details. Please provide feedback to the developer or via the ASCOM Talk User's List.Meade Universal Driver Project (June 2014)
Link 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.
