[SeeStar S50] It works fine, but I noticed from the very first time I turned it on, there was a "high" pitch noise for as long as it is turned on, almost like a coil whine. Just checking if anyone else has something similar and if I should be concerned? Its not overly loud, but its noticeable if there is no other sound in the vicinity.
Here is a video of the noise.
