How To Construct A True Newtonian Astrograph

Dec 01 2022 10:26 AM | Gork in Articles

I finally decided that I was going to build my own 10” astrograph incorporating as many characteristics that I was able to find. The project differed from what you would expect in a field so dependent on pre-planning. The project was really more of an evolution than a clearly documented plan. It is for this reason that my trek began with a collection of assorted hardware, and a scratch pad.

Questar Standard: Tristand vs. Astropier

Nov 13 2022 10:46 AM | justfred in Articles

I have the Tristand for my ‘66 Questar Standard and have used it for several years. It’s great. Sturdy, easy to polar align, compact design with folding legs. I really like it - but I have always wondered about the Astropier: would I like it better?

GSO 6” f/4 Newton

Oct 01 2022 05:00 AM | Gianluca67 in Articles

The GSO 6” f/4 Newton can become a real astrograph capable to deliver beautiful images of the night sky and to enable the observer to do science in the field of photometry and spectroscopy but it definitely needs some modifications as the mechanics of this scope is totally inadequate to boost its potential. All the modifications I have made turned a mediocre instrument into an amazing scope.

Exploring the Universe - Size Matters But it's Always a Compromise

Jul 01 2022 05:00 AM | MarkMittlesteadt in Articles

Maybe 50 years ago, back when light pollution didn't rob us of the glorious views we no longer have access to, as a child of the 60's I used to lay on my back out in the yard at night and just look up and wonder what was "out there". I watched with hypnotic interest on our old black and white TV the first humans land and set foot on the Moon. I was hooked. I even had models of the Apollo rockets, orbiter and lunar landing module and of course toys of all kinds that were about pretending to be an astronaut. My imagination was consumed with what was "out there" in the Universe. It was more obsession than interest.

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.

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.

Replacing a Damaged Dobsonian Mount

Dec 02 2021 10:39 AM | Oldskaterman in Articles

Considering the choices available for replacing my damaged Sky Watcher Dobsonian mount, I found the same size Apertura mount the easiest and most cost effective solution. In addition to the ease of modifying the Apertura mount, the superior construction and improved azimuth bearings noticeably improved overall satisfaction with this approach.

Fairhavens II

Nov 01 2021 05:55 PM | Gork in Articles

My last article was an overview of Fairhavens, my first dedicated observatory, along with its untimely demise. It is now five years later and I am ready to try again. Being a rental home I could not build a permanent structure (I couldn’t afford one anyway). So, I started looking for a temporary structure that would protect my gear from the elements and still leave room to move about.

Fairhavens Observatory: The Story

Oct 01 2021 05:00 AM | Gork in Articles

This is the story of how “Fairhavens” (the name of my observatory) came to be. My life style was never one that required planning: It was a reactionary type of life. As an enlisted soldier I only followed somebody else’s plans and ideas. But now I was in the situation that I had to actually plan.

A Build-Your-Own C-14 Focuser

Oct 01 2021 05:00 AM | redfordg in Articles

I couldn't find an off the shelf EFocuser for my C14 (pre-2006), so I built my own which allows for Hand Held Focusing control and/or USB remote focusing. No mechanical modifications are required to the telescope. I wanted to make this available free to my fellow Astronomy geeks. My only hope is that it will help someone. Shame to go through all of this and not share it.
