Three Simple iOptron Improvements

May 01 2022 05:00 AM | Michael Covington in Articles

In what follows I want to tell you about three things I've done to improve my early-model iOptron GEM45 mount. With a bit of adapting, you can apply the same ideas to many other mounts, both iOptron and other brands.

Cosmic Challenge: Quasar 3C 273

May 01 2022 05:00 AM | PhilH in Phil Harrington's Cosmic Challenge

Whenever my neighbor (I'll call him "Joe") sees me at one of my telescopes, he'll come over and ask "so, how far can you see with that thing?" Every time! You've also probably met someone like Joe. Well, unless you have a double-digit telescope, your answer should probably be "2.4 billion light years."

Cosmic Challenge: Polarissima

Apr 01 2022 05:00 AM | PhilH in Phil Harrington's Cosmic Challenge

In astronomy, as in real estate, we have the Three Ls: location, location, location. NGC 3172 is a challenge for all seasons -- literally -- as its location keeps it above the horizon throughout the year no matter what time of night you are looking. That's because NGC 3172 lies within 1° of the North Celestial Pole, closer than any other NGC object.

Cosmic Challenge: Beehive Galaxies

Mar 01 2022 07:00 AM | PhilH in Phil Harrington's Cosmic Challenge

Hidden among the stars of M44 are no fewer than eight distant galaxies. Until 1987, most of us knew nothing of them. That was the year when the Uranometria 2000.0 star atlas was published. It showed the sky to a depth never before captured in a convenient star atlas format, and immediately shed light on thousands of objects that no amateurs, except possibly for a few extreme deep-sky hunters, even knew existed.

Unique Binary Globular Cluster Delivered By The Sagittarius Dwarf Spheroidal Galaxy, M53 and NGC5053

Feb 01 2022 02:14 PM | rekokich in Articles

It is irresistible to imagine the environment within a tightly organized globular cluster. The night sky would be sublime with a million visible stars, and a bird's-eye view of the entire Milky Way galaxy. How much earlier would astronomy and associated technology develop among an intelligent species living on a world graced with such inspiration? Unfortunately, complex life in globular clusters is extremely unlikely due to virtual absence of heavier elements. It is not even known if rocky planets can form in that environment. Therefore, such spectacles are probably unseen by intelligent eyes, and must remain confined to our imagination.

Hubble Optics 14 inch Dobsonian - Part 2: The SiTech GoTo system

Feb 01 2022 11:14 AM | Chris Westland in User Reviews

This is the second in the set of reviews about my Hubble Optics 14” Dobsonian, where I relate the performance of the installed GoTo system. I completed adding the Hubble Optics / SiTech GoTo system to my Hubble Optics 14” f/4.6 dob, but did encounter a bit of a learning curve on this, one which I’d like to share with anyone planning on upgrading any Dob to full GoTo.
