Advanced control for your Go To or Push To
Telescope

TheSky Professional provides an extensive set of astronomical catalogs and the tools to quickly access information from them. The "core" databases include many industry-standard astronomical catalogs. They should meet your needs whether you're star hopping with your telescope, taking CCD images of faint galaxies, or computing sub-arcsecond astrometric positions of minor planets.

TheSky Pro also includes an extensive set of optional "non-typical" Sky Databases (SDBs) that contain many unusual or hard to find objects that may not appear on standard astronomical catalogs.

Core Astronomical Catalogs

TheSky Professional includes databases of celestial objects from the standard astronomical catalogs in the table below. Use TheSky Professional's Find Command to locate any object from any of these catalogs by name, catalog number or other standard cross references (where applicable).

Catalog Type Name of Catalog Object Count and Limiting Magnitude

Stars

Hipparcos/Tycho Stellar Catalog

TheSky's core star catalog for brighter stars contains 1.2 million stars (complete to about magnitude 12).

Gaia Star Catalog

The complete Gaia DR2 catalog occupies over 1.2 TB of disc space and can be downloaded from the Gaia archive page.  When configured to use the complete Gaia catalog, TheSky Professional’s Sky Chart displays every star from the Gaia
catalog along with the accompanying Gaia “metadata” as described
on the Gaia website.

If you do not have a super-fast internet connection, or do not want to clutter your computer’s drive with unnecessary data you may not need, TheSky Professional supports two Gaia star catalog subsets that should suit the needs of most:

Small Gaia Subset: The smaller Gaia subset contains the RA, Dec, G/BP/RP mean magnitudes, spectral class, star distance in light years, stellar temperature, and proper motion for about 100 million stars that are equally distributed across the celestial sphere.  It is ideal for determining the astrometric solutions.  This database is included with TheSky's full installers.

Large Gaia Subset: The larger Gaia subset contains 1.7 billion stars, with the same information as the smaller subset described above.  Successful Image Links are possible using optical systems that produce fields of view as small as about 3 arc minutes.  This database is available on the Database Add On Version 3.

Want More Data?

There are literally millions of astronomical catalogs, and TheSky does not include them all.  If TheSky's supplied databases of objects are not enough, and you wish to access a database that is not currently included, please let us know, and we'll try to add your database to future updates, or post it for download.


Ephemeral Data

TheSky predicts and charts the positions of comets, minor planets, and artificial satellites.  The data required to accurately display these objects changes frequently and must be updated from different sources on the web. Use the links below to download updated orbital element data.  TheSky can be configured to automatically download TLE datasets each time it is launched.

Use TheSky's Edit > Find command to locate any object from these catalogs.

My Chart Elements

TheSky Professional allows you to add objects to the Sky Chart (such as stars, galaxies, labels or reference lines and more) so that you can generate your own databases.


Photographs

TheSky Professional includes photos of many deep-space objects, planets, the Moon and more.

  • Over 13,000 monochrome photos from the NGC and IC Catalogs.

  • Over 95,000 Digitized Sky Survey thumbnail photos PGC Catalog galaxies.

  • Photos of every object in the Messier catalog.

  • Photos of solar system objects, including images from the Mars Rover and other space missions.

  • Over 1000 high-resolution photographs of the Moon that can be labeled by crater (name and size).

  • Miscellaneous comet, asteroid, and Apollo mission photos.

TheSky has extensive features to operate your astrophotography equipment.

 

The table below lists the "go to" and "push to" telescope models supported by TheSky Professional.  For step-by-step setup instructions on how to setup and control telescopes with TheSky, see Telescope Control in TheSky Professional and Serious Astronomer User Guide.

Telescope Control Features

TheSky Astronomy Software was first used to direct and control telescopes back in 1988.  Since then, we've enhanced and refined the user interface based on feedback from thousands of passionate astronomers.  The result is a friendly, easy-to-use interface, packed with a powerful feature set.

about setting up and using iOptron mounts.

To date, iOptron has released three
different versions of thier serial commands.

  1. Version
    1.0*

  2. Version
    2.0**

  3. Version
    3.0**

* Earlier model Optron SmartStar mounts used the Silicon Labs CP210X USB to UART Bridge for serial communications on macOS and Windows.  This UART requires a Virtual Serial Port Driver to be installed before TheSky can communicate with these model mounts.

The CP210x USB to UART Bridge VCP Drivers (VCP Driver Kit) are available from the Silicon Labs web site.

Note that iOptron mounts using the serial command protocol version 2 and later do not require installation of a VCP driver.

**
TheSky's native iOptron support is compatible with iOptron serial command version 1.0 and 2.0, only.  See the X2 Plug-In Compatible mounts below for details about controlling
iOpton mounts that use version 3 of the iOptron serial command protocol.

Professionals native Astro-Physics mount driver states that firmware version
G or later is required to control Astro-Physics compatible telescopes.
Note that if you own an older model AP controller that uses an earlier
firmware version, TheSky Professional will still control it; however,
newer firmware features will not be available.

Software Bisque strongly recommends using the latest available
firmware for your telescope
.  Contact Astro-Physics for details
about upgrading your mount's firmware.

USB Adapters

Many commercial telescope mounts communicate with the personal computer
using RS-232
serial communication.  In order to communicate with modern computers
that no longer include RS-232 DB-9 serial ports, a USB
adapter
is required.  FTDI-based USB adapters, like this
one
, are compatible with most operating systems and do not require
installation of a software driver.
