In my second-to-last blog post, I talked a lot about the Bortle Scale. What is it? Why should you care? Invented by John Bortle in a 2001 Sky & Telescope article, the Bortle Scale is an effective way for you to objectively assess the darkness – or, unfortunately, the brightness – of your sky, or […]Read More September 28, 2018: The Bortle Scale, or Why Gas is Your Friend
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. Yeah, that’s it. Anyway, thanks to a fellow DASer, Noel, for inviting me and another DASer, Joe, out to […]Read More September 15, 2018: The Stars At Night, Shine Big and Bright . . .
Just a semi-brief “observing report” for the Perseids and some other stuff. I went out to the DAS Dark Site on Friday, Saturday, and wouldncha know it, on Sunday, too. Well, more Monday really, by the time we got there. It was definitely a fun astronomy extended weekend. On Friday night there were about a […]Read More August 17, 2018: Meteors and Coyotes and Rattlers, Oh My! and a Mea Culpa
On Wednesday night, after last month’s windy failure, I finally got a good night out at the DAS Dark Site. Well, half a night anyway, before I felt like a popsicle and packed it up and went home. I was out for three hours, but what a three hours! The afternoon was glorious in the […]Read More March 9, 2018: Finally! A Clear But Cold Night at the Dark Site

As the eight long-time readers of this blog may remember (although they probably won’t), one of my absolute pet bugaboos is the complete and utter inability of weather forecasts to get it right. They just can’t. Not even frickin’ close. But they give the illusion that they can, this illusion of supreme […]Read More February 20, 2018: Dark Site Disappointment and Mount Mastery
Well, I’ve finally done it! I’ve finally bought my long sought after Celestron 9.25-inch optical tube assembly (OTA). I had been very patient, waiting and waiting for a used one to come up for sale at a reasonable price with the newer Starbright XLT coatings, as they have about 10-15% greater light transmission than the […]Read More January 8, 2018: The C9.25 Of My Dreams Is Here! And the Trapezium Falls to its Might!
Well, it’s official! With apologies to Al Jolson, just a quick blog post to note that I’ll be moving from Manhattan to Denver at the end of this month. Yes, it will still be plenty light-polluted in Denver, but obviously nowhere near the same level as it is here in the light-pollution capital of […]Read More July 19, 2016: D-E-N-ver, Here I Come!
