Polar Alignment Made Easy

I may have just found a great solution for achieving very good polar alignment with any telescope mount.

There is this little piece of software called “SharpCap” ( http://www.sharpcap.co.uk/ ). It’s a very clever piece of software that uses a webcam or an astronomy camera to assist with focusing, stacking, polar alignment and much more.  Unfortunately SharpCap does not support DSLR cameras as a video source. It supports some of the available astronomy cameras such as ZWO, QHY, etc.  If you want to use SharpCap you have to have a camera that is supported. I was on my way to purchase a ZWO camera to do this when I read a forum post on Cloudy Nights ( https://www.cloudynights.com/topic/545643-sharpcap-polar-alignment-experiences/ ) where someone mentioned that they are using another piece of software to allow them to use a DSLR as a webcam and that SharpCap actually processes the DSLR image seamlessly.

“SparkoCam” ( http://sparkosoft.com/sparkocam ) is providing the capability to use your Canon or Nikon DSLR as a regular webcam. When installed, SharpCap will recognise SparkoCam as a virtual webcam and process the DSLR live view images directly. No need to purchase a separate camera to work with SharpCap.

The process is quite simple, install the DSLR on your mount pointing towards the celestial pole. You would obviously do a basic mount alignment to get the camera view close to the pole, at least to within about 5 degrees. Now activate SharpCap and follow the instructions to get to an accurate alignment. This process will work with a tracking mount as well as a manual equatorial mount.

I have everything installed now and will test under the stars as soon as possible. It is raining outside at the moment, as can be expected….

    Have you managed to try out the polar alignment using Sparkocam and Sharpcap. I am going to try the combination next time I see any stars & I’m interested in any results you got. I was also thinking of a ZWO and guidescope to align my Astrotrac but there’s a great saving if this works.

      Hi Laurie. Not yet, very busy at work at the moment but planning to use it next weekend with New Moon. Will update post with results.
