The EARTHA project is the result of several years of study, planning and failed attempts that we have overcome, however, availing ourselves of capable suppliers and the certainty of our project.
Field tests carried out for a long time have shown that the tracking system at variable latitude works well from 30 ° to 60 ° of inclination.
There have been many difficulties to solve, one of which has committed us most; the variable declination. In fact, being able to vary the latitude according to the observation area is not easy.
Another challenge was the resolution of the drag problem that placed limits on the tracking time. In fact, after passing a certain time tracking, the system began to slip and no longer "grip" making the observation "useful" only a few minutes. Now it comes to an hour tracking.
We have implemented load capacity of the previous version; now it is possible to use Dobson up to 24 "and up to a weight of 80 kg.
The platform has the possibility to change the latitude of 2 ° in 2 ° so you can bring it to the various “star party” even if with considerable variation of latitude knowing that you will have to act only a little on the speed control after having changed the latitude.
With the remote control you can increase or decrease the tracking speed and, with a dedicated button, you can return the platform to the starting position.
This electric system is powered by a 12Volt battery (not included) that is positioned under the basament.
Many other technical and mechanical details are described in this manual that will confirm the right choice of your purchase and will give you proof of superior quality by putting you in the best condition for your astronomical observations.
