About Orion Ranch Observatory

Welcome to Orion Ranch Observatory!  Located in the Texas Hill Country, northwest of Austin, TX, Orion Ranch is the the home to a 600 square foot roll-off observatory and warm room in addition to the livestock and wildlife.

The observatory equipment includes two 11″ Schmidt-Cassegrain telescopes (SCTs), one dedicated to visual use and the other for astrophotography.

For wider field work I also have a number of refractors from 3″ to 6″ in aperture.

For a bit of a historical perspective on how this observatory came to be, check out this blog article on the culprit that started it all.

Right now the primary feature of this site is the picture gallery, of course!  From there you can see samples of my astrophotograph and other artistic photograph,  as well as the entire construction history of the observatory and various technical topics.  You’ll also find a weather page showing the conditions at the observatory, updated every 15 minutes, and the clear sky chart on the main page.  There’s also a “webcam” link on the weather page that will show you a full size view of the current sky conditions over Orion Ranch.

I hope you enjoy your visit.

    Thanks for sharing the pics of your Observatory. My husband is so into this stuff, I had bought him a little telescope a few years back and we will try to get out back when things are going on, but his scope is not like yours. He was amazed at the pics you had taken, again thanks for sharing.

    My brother owns a ranch bordering the east city limits of Burnet, TX where I keep an 8″ dob to use when I visit. I have also observed and spoken at the Eagle Eye Observatory on Lake Buchannan where the light pollution is not as great. Hope the Orion Ranch is west of Llano. The skies get incredibly dark about 10 miles west of Llano!

      Thanks. Actually, it’s in the Bertram area, which is about 10 miles East of Burnet. Pretty much surrounded by light pollution, but still better than closer in to Austin!

    Hi Michael!

    I saw your post on CN
    I have a CGE Pro (most recent revision, as is yours), and am losing my mind trying to get the RA worm meshed properly. apparently at some point, both of the rear locknuts came loose, and allowed the whole assembly to move side to side, also, the silver adjustment screw by the spring, the nut apparently vibrated loose, and is allowing free travel.
    I have tried and tried, and Celestron hasn’t been of much help, do you have any insight as to the magical incantations that must be made to get this thing properly aligned/meshed?

      Hi Lee,

      I played with it a bit and think things improved at least for a while, but can’t say I think I’ve resolved my issue completely. I certainly haven’t dug into all of the components so I can’t really tell you much about what you’re facing, although I sympathize with your plight! I had something similar when I first got my Deluxe CPC where I discovered that the pin that the whole motor assembly twists around to mesh the worm had slid out on the DEC axis and the whole thing rocked back and forth on half the hinge. I’d suggest responding to the post or starting a new one on CN and getting what help you can there. I’ll provide feedback as I’m able, but detailed pictures of everything you’re seeing is probably a good starting place.

      Good Luck!
