Obs Log №1 · First Light
For the dark-adapted.
The market sells NASA souvenirs, galaxy-photo prints, and insider text jokes. We draw the hobby's own notation — atlas symbols, true light paths, log sheets in UT — correctly enough that a club member nods at it across a star party.
A circumpolar star chart centered on Polaris, drawn from real coordinates: bright stars of Ursa Major and Minor, Cassiopeia, Cepheus, Draco, Cygnus, Lyra and their neighbours, with declination circles and hour lines. Decorative; the site's content does not depend on it.

8-inch Dob vs 4-inch Refractor: Which First Scope Is Actually Yours?
An 8-inch Dobsonian gathers four times the light of a 4-inch refractor, but the big tube only wins if you'll store it, lift it, and drive it to dark skies. A field guide to picking your first scope by aperture, portability, Bortle class, and what you actually want to observe.

First Light: What to Point Your New Telescope At Tonight
First light is the first look through a new telescope — and it deserves a plan. Cool your optics, skip the high-power eyepiece, and climb a target ladder from the cratered lunar terminator to Saturn's rings, Albireo's gold-and-blue split, and the grey glow of M13.
