Part three? What happened to part one and part two? Oh, there they are. The tl;dr version of those posts from last year is first that I had the wrong power supply for this mount, and then when I got the right power supply, the mount worked very well with my little 8-pound Mak on […]Read More December 12, 2018: Orion Sirius Pro AZ-EQ/G, Part III – Customer Service
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
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
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
Ugh. Just ugh. 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!
Power problems solved! The Celestron Lithium Iron Phosphate Powertank (which I’ll more fully describe below) puts out 3 amps, and powers this mount excellently. No more stutter-slew or stutter-track as I described in my last post. The mount just works great. Finally. But how well does this mount really work? I tested it two ways […]Read More June 16, 2017: The Orion Sirius Pro AZ/EQ-G mount, Part Two – Great Locating and Tracking! and the Celestron Lithium Powertank
