Raspberry controlled HEQ5

Last night I could do my first test with a Raspberry controlled HEQ5 mount. Worked much better now compare with all problem I had one year ago. I succeeded to: Plate solve, auto focus, take images. What's left to fix, auto guiding, GPS module to communicate.

Tonight it looks to be a clear night too. I will do a new test run, concentrate me on the auto guider, now in the beginning I use the internal guider, later maybe I change over to PHD2. Very exiting.

My setup of HEQ5 and a 300 mm Pentax 645 lens:

Yesterday I got a massive help from my friend. It was the stup of GPS unit for the Raspberry which has caused me problem the last 5 years.

Now we got the GPSD driver to work direct with a GPS dongle:

And the GPS NMEA where the Raspberry get the clock and psition from a smartphone:

Very glad to solve these problems.

Next step is to install KSTars on a Android pad. My own was to old to install the software.

Hi,

Sounds like a real learning experience; but totally worthwile when you re making such good progress. I have an ASIAir pro and the freedom of controlling everything from a smartphone (as you appear to be doing) is great.

Cheers

Hi,
I only use the smartphone to set clock and position from its GPS and adjust focus on the guide camera lens. But to control the total setup feels for me impossible. How do you manage to do that ?

I will later change from lap top to Android pad to save weight and power consumption. The lap top I have today has very low resolution, 1366x768. Very difficukt to work with.
