Hello everyone and welcome to BD Observatory!
I'm Bogdan Damian and as a hobby astronomer I like to talk about astronomy and astronomy related topics. Here on my channel I upload quality videos about eyepieces, telescopes and telescope accessories every two weeks.
If this sounds interesting to you, then check out my videos and also consider subscribing to my channel.
Thank you for your support!
