Damn. Deactivated last August. In case work ever finds you in a less light polluted city, this is a nice tool for finding good spots for clear skies. (1) Booyah. IIRC the diameter is a measly 1/2", and it'd really be a nostalgia/feel-good DIY fix more than anything. cloudynights (3rd link) was one of the first places I got the idea for jerry-rigging. btw, LOL (in awe) @ how awesome this forum user's setup is: Using the dinky thing AS A FINDER. Scrolling around amazon now for Telrads. Brilliant point about use of filters. That concept didn't transfer from in-class lecture brain to real-life brain. (DOH) This is new info to me, and added to the list. Also, in hindsight, microfiber cloth would have done wonders for the quality, too. (2) This, I don't have an accurate read on given IL desert has ~100m more on my city (Northern FL) on average. Though I can accurately write that the humidity was out in full force last night - more than the usual in FL. (3) I found the spots based on other redditors' suggestions. I have yet to see anyone else out there yet. Then again, 'small' city = small sample size = small chance of seeing people, etc. A meteor shower+picnic sort of date is in my back pocket, but that's stretch until very comfortable with someone [who is comfortable with being up at peak hours].Seeing as I'm at sea level in Seattle, there's very little reason to try.
I will gladly spill whatever tips I can all over anyone else foolish enough to stand up a tripod.
it looks like the weak point in that scope is the right angle prism. Which is optional and can be replaced.
