Since I had no chance to see Geminids meteor shower due to clouds, I've decided to improve my polar scope illuminator. If you bought Sky-Watcher Star Adventurer 2i star tracker, pro package comes with polar scope illuminator which is too dim, at least for my Bortle 7 area it's absolutely useless. Someone may say it's just bad unit, but trust me there are lot's of ppl having the same problem, so it's probably flawed design. #astrophotography Here how it looks and solution below:
Unscrew 4 screws to get access. I think problem with it that they placed resistor which is too much for that battery and rest of the circuit, that what makes diode underneath this glass too dim(see red circle for resistor). What we need to do is to by pass it, see one of the blue lines, either one would work. My soldering skills aren't that great so I just soldered over resistor. WARNING it will void your warranty, do it at your own risk. That worked for me. Final result is in the picture.
