McDonald Observatory

last week I spent boiling in the Texas Sun….

This pinhole image of McDonald Observatory proves it!


No special effects were added

The boiling sky is indeed an artifact of some sort, but it did feel this way when I was there!

The Gang at the Fort


The past few days were absolutely wonderful!

Almost perfect weather ( a little dewy) and great friends at Fort McKavett.

Was great to see everyone and visit….see ya’ll next Spring!

BTW- I saw some nice Orionid meteors while there.

Gotta love Cart away concrete!!!


I don’t think we could have mixed 45 of the big 80 pound bags of quikrete to pour in the hole for the pier mount…

so we went with the haul away concrete and it worked really well.

Our friend and fellow astro buddy Gordon helped us, which made the job a lot easier even though we were running around like three year olds on too much sugar for a while.

The concrete had the consistency of pancake

batter (with rocks) or a “slump” of about 5.  It was veeeery nice!

After the Pour


After a hurry, hurry, hurry, and then waiting for the concrete to dry…this is what we wanted this part of the observatory that holds the pier to look like.

There’s a little over a yard of concrete in the sonotube with some wire some re-bar and a few drops of sweat.

The next step is to build forms for the surrounding slab that will support the observatory walls.   More to come………………….
