During a failed attempt to observe and photograph the Camelopardalids meteor shower, I found out that the finderscope of the 4SE was not working. If you have not done this, try doing it, it is ridiculously hard to successfully aim the telescope at anything if your finderscope is not working. After testing with multiple batteries, my immediate worry was that the LED in the finderscope may have burnt out. If this was the case it would be quite hard to fix it. That's when I decided to dismantle the finderscope to pinpoint what exactly went wrong. Removing the finderscope from the telescope is quite easy. You need to unscrew the two bolts on the side of the finderscope, just under the switch and the calibration screws. Once done, you need to remove the unscrew the calibration screws themselves. You need to hold the calibration screw with one hand and unscrew the bolt. The calibration screw will otherwise turn along with the bolt. And this is what the inside look...
