Astrofinder | Software

Before modern smartphone apps, AstroFinder was a pioneer in consumer-level telescope control. It was designed to run on Windows PCs, allowing users to select a celestial object on their screen and have their telescope automatically "slew" (move) to find it. This was revolutionary for backyard observers who previously spent hours squinting at paper star charts. The Missing Link: Cables and Kits

Unlike higher-end Meade telescopes that used a standard #505 serial cable (relying on basic RS-232 protocols), the entry-level telescopes used a #494 Autostar controller. The #494 handbox did not have a built-in serial port. Familiarize yourself with the interface : Take some

  1. Familiarize yourself with the interface: Take some time to explore the software's features and options to get the most out of Astrofinder.
  2. Use the object database: The object database is a treasure trove of information on celestial objects. Use it to learn more about the objects you're observing.
  3. Customize your star charts: Experiment with different map projections, scales, and object filters to create customized star charts that suit your observing needs.
  4. Stay up-to-date with software updates: Regularly check for software updates to ensure you have the latest features and data.

AutoStar Integration: The software acts as an extension of the AutoStar hand controller, allowing for easier navigation via a full-sized monitor rather than a small LCD remote.

3. Sensor and Eyepiece Simulation

A unique feature of AstroFinder software is the "Sensor View." You can input your specific camera sensor size (e.g., Sony IMX571) or eyepiece focal length. The software will then overlay a rectangle on the sky showing exactly what your imaging frame will capture. This eliminates guesswork when framing the Andromeda Galaxy or the Veil Nebula.

  1. No Built-in Astrometry – It relies on pre-existing WCS solutions. If your images are not astrometrically calibrated (using e.g., PinPoint, Astrometry.net, or SCAMP), AstroFinder will return empty results.
  2. Primarily Command-Line – Many versions lack a polished GUI. For users accustomed to point-and-click, the learning curve is steep. Expect to write scripts or learn SQL-like query syntax.
  3. Narrow Use Case – This is not an image processing, stacking, or photometry tool. You will still need separate software (e.g., AstroImageJ, Tycho Tracker) for measurement once AstroFinder identifies the correct frames.

AstroFinder software has effectively lowered the barrier to entry for complex astronomy. It turns a daunting expanse of black and white dots into a navigable, educational, and deeply rewarding map. Whether you’re hunting for the Andromeda Galaxy or just learning the names of the summer stars, this software is your ultimate guide to the final frontier.
