Although for some it’s tax season, for we astronomers, Jupiter season is finally here! Hooray! First of all, I’d like to express my appreciation to everyone who visited my blog over the past few days to read my post about the amazing Dragonfly Telephoto Array. That post was the most viewed post I’ve ever written […]Read More April 17, 2017: It’s Jupiter season!
Normally, I curtail my astronomical activities just before midnight so that I don’t disturb my family coming in the front door late at night from an evening’s observations. However, with the family away for the holiday week, I was a bachelor for awhile and didn’t need to curtail anything. Unfortunately, the sky had something else […]Read More April 17, 2015 – Saturn and the Glorious Globulars
The same day as the Levenhuk/Baader solar filter arrived, another filter arrived, too: The Baader Moon and Skyglow Filter. Suh-weet! So, between the sun and the night sky, it was really a very full and enjoyable day and night of observing. The M&SG is, in one sense, a weaker version of the Orion Ultrablock filter […]Read More March 19, 2015 – The Baader Moon and Skyglow Filter and the Crabby Astronomer
Right at the same time as I got the Ultrablock, I also received my new Celestron Luminos 10mm eyepiece. I had ordered it in early February, using up the last of my Amazon gift card. For some reason, there was a two-week delay in getting it out to me, which is pretty unusual for Amazon. […]Read More February 27, 2015 – The 10mm Luminos Eyepiece and EOFB
Last week I went out to once again hunt my elusive quarry, my very own personal white whale, Jupiter’s Great Red Spot. Unfortunately, because of my own ineptitude, I misread Sky & Telescope’s GRS transit calculator and thought I’d be able to see the transit that was to occur a bit after midnight, Eastern Time. Of […]Read More February 14, 2015 – The Great Red Spot is Mine!
Before I get to the main topic, let me just do a quick recap of my observing session last night. I went out to take another look at Jupiter, to see both the Great Red Spot, and a transit of Europa. According to this listing from Sky & Telescope, the Great Red Spot was supposed to be […]Read More December 16, 2014 – What is “light-polluted astronomy”? What’s with that hyphen? And Europa’s shadow!!!
As promised, I can finally give you the lowdown on how good the TeleVue Plossl is. It ain’t worth it. I observed Jupiter tonight, for almost a solid hour, with a couple of breaks for the Geminid meteor shower. (I only saw one, out of the corner of my eye.) I switched back and forth […]Read More December 14, 2014 – Upgrading the Mak, Part 3A – 8mm TeleVue Plossl vs. 9.7mm Meade 4000 SuperPlossl, Bahtinov mask, Lord mask, diagonals
