... on a telescope mount.
Hi,
I just got a telescope mount into which a Polar aligment scope can be installed. This Polarscopes do have a reticle which can be illuminated by a LED.
Now the main board has a jack for the LED driving. I measured the output voltage of this Jack and it goes up to about 8V, but as I know a LED normally works up to maybe 3 to 3.3 volt.
The hand controller of the telescope mount has in its function menu the possibility to adjust the LED intensity.
Due to the high voltage I assume that the main board controls the LED intensity by limiting the current. Is that possible ?
Thanks
