With apologies to Inigo Montoya, you killed the word theory; prepare to die. Heh heh, okay, a little more seriously, let’s talk about the word theory and what it means in science. You often see the word bandied about in discussions, with the inevitable “that’s just a theory” thrown in to try to cut off […]Read More September 21, 2018: I Do Not Think Theory Means What You Think It Means
Banner photo credit: Ian Norman . . . deep in the heart of Westcliffe! I just got back from southern Colorado, and boy are my arms tired. Wait, that’s not the joke. My tires are tired.

So, let’s say you bought your first scope for around $150 to $300 – maybe it’s the Astronomers Without Borders One Sky scope, or one of its clones, like the Meade Lightbridge 130. Perhaps you’ve bought a refractor, like the Meade Infinity 102. Or, it could be that you bought something like the Celestron Astromaster […]Read More July 27, 2018: Goto Telescopes / Mounts
The three longtime readers of this blog might recognize the title of this post; I wrote another post about the shortcomings of my local observing site just short of two years ago, right after I moved into my apartment in Glendale, a tiny little independent city completely surrounded by Denver. Up until now, I’ve basically […]Read More July 14, 2018: My Local Dark Site Ain’t So Dark, Redux; and No-Detail Mars, Redux
