When I was a kid my parents gave me a Celestron refracting scope since Halley's comet was on its way. I don't remember the aperture, but I bet it was 60 or 70 mm. I had a good time with it and actually managed to locate Halley's comet which wasn't more than a ghostly blob through the telescope. I loved astronomy, but it wasn't powerful enough to really keep me going. As an adult, I had convinced myself I wouldn't really care about using a telescope anymore. I thought a proper telescope would be too expensive, it's too bright in town to really see anything and, I mean, you can just pull up better pictures online, Right?
My wife gave my youngest (and essentially me) a 90 mm Celestron refractor for Christmas. I've been using the shit out of it and I'm back to being obsessed with astronomy. I've been looking at the moon, found the orion nebulae and made three attempts at seeing Comet Wirtanen, but no luck. I wish I'd had it last summer for all the planets that were in the evening sky. Now I want a larger telescope again.
