AstroDSLR

AstroDSLR is digital camera tethering and remote capture application specialised for astrophotography.

AstroDSLR controls ISO, aperture (if lens mounted), shutter speed and BULB exposure length, exposure compensation, metering and focusing modes, white balance, image quality and format. It can preview (optionally using LiveView) or capture and save images to selected folder with any file name prefix, count and time lapse, browse captured images and show them in Finder, zoom and stretch them automatically or manually. It can measure FWHM, HFD and the drift of a selected star to help easier and faster focus and align your equatorial telescope mount. Captured images can be plate-solved using public astrometry.net service or local Astrometry for OS X application.

The built-in INDIGO driver implements PTP-over-USB protocol and, in theory, it can work with almost any Nikon DSLR, Canon EOS DSLR, Sony Alpha DSLR-like or mirrorless camera. Not every feature is supported for every camera (e.g. no LiveView or manual lens drive with older Nikon and all Sony cameras or BULB mode with Nikon cameras works only for D600, D5200, D7100 and later models), but it doesn't mean, that such camera can't be used. As far as this application is based on INDIGO framework, it can use many INDIGO drivers for focusers for astronomical telescopes. Out-of-the-box it contains the following drivers:

  • PTP-over-USB CCD driver for Canon, Nikon and Sony Alpha cameras,
  • CCD and focuser simulator drivers,
  • ZWO ASI focuser driver,
  • FLI focuser driver,
  • Shoestring FCUSB and DSUSB drivers,
  • Focuser USB v3 driver,
  • WeMacro Rail USB and BT drivers,
  • MJKZZ macro rail USB and BT drivers,
  • RigelSys nSTEP and nFOCUS drives,
  • MoonLite focuser driver,
  • Optec focuser driver (untested),
  • LakesideAstro focuser driver (untested),
  • Deep Sky Dad AF1, AF2 and AF3 focuser driver,
  • Baader Planetarium SteelDrive II focuser driver,
  • AstroGadget FocusDreamPro focuser driver,
  • Lunatico Limpet/Armadillo/Platypus Focuser driver,
  • PlaneWave/Celestron focuser driver,
  • RTS-on-COM shutter driver.

AstroDSLR is developed and/or tested with Nikon (D50, D70, D90, D3000, D5100, D5600, D750, D850), Canon (1000D, 600D, 6D), Sony (A5000, A7, A7S, A7RII) and other. Nevertheless, even with the best effort we can’t test all cameras, so please download a trial version and test it with your camera before buy it! If it will not work, let us know, maybe we can still help you and fix it.

Even if it can be used separately, it is meant to be used together with AstroTelescope and AstroGuider. Application communicates over INDIGO protocol and it can be used to integrate with any INDIGO 3rd party application as well.

To run AstroDSLR you need Apple Mac running macOS Sierra or later.

If you want to use AstroDSLR on older version of the operating system, you can try AstroDSLR 1.3 based on Nikon and Canon SDK.

If you want to use last ICA based AstroDSLR on pre-Catalina systems, you can try AstroDSLR 3.11 based on Nikon and Canon SDK.

You can read Getting Started or to watch video tutorial to learn more and if you will have any problem with some of our products do not hesitate to contact us on info@cloudmakers.eu or users group forum.

If you want to do the same with your cooled astro camera, you may want to check AstroImager as well. Read more »
