Using Altair GPCAM as Digital Finder Scope

You can use your Altair GPCAM as a digital finder scope with the latest version of AltairCapture. Here’s how. Firstly mount your GPCAM with suitable C-Mount or CS-Mount lens, pointing in the same general direction as your telescope.

Then click on the reticule buttons at the top of the screen and choose the one you like.

Now here’s the cool part – the reticule can be moved around by clicking the screen, and the position of the reticule is saved for your next AltairCapture session. So just zero in on a star or object in the main scope, and click on it in AltairCapture. Now ever time you click the reticule button, you’ll see it pop up in the correct position.

Using the Altair GPCAM as Digital Finder is a great time saver for long exposure imaging. You can check your scope is pointed in the right direction, and of course keep an eye on approaching clouds and aircraft. That way you can cancel any long exposure frames and restart without any wait. Image Credits Chris Heapy:

You can attach your GPCAM to your telescope using the GPCAM Multi Purpose Camera Clamp

With this accessory, you can attach your GPCAM to your telescope rings or Vixen/Losmandy plates (Std. M6 1 or 2 hole pattern) like this:

GPCAM-CLAMP11
GPCAM-CLAMP5
GPCAM-CLAMP12
GPCAM-CLAMP3

You can also attach the GPCAM to a camera tripod with standard 1/4″-20TPI Photo Tripod thread. The clamp attaches in the vertical (for all sky imaging to capture meteors) or the horizontal position (for daytime timelapse cloud videos and so-on).

You can even attach your GPCAM to the Altair Astro XYAZ Micro Adjustable Guide Head if you want to fine adjust pointing.
