  • Re: Updates, observing

    It's been a bit quiet here, and I've been too busy working and traveling to write articles about this year's trips. I hope to begin working on those soon, one

    Mike, The seeing forecast for CSC is fairly accurate, as that's largely dependent on upper-air patterns that show up well in computer weather models. But the

Group Description

A place to discuss high-quality reflecting optics, how to get the most from them, and associated issues. You are invited to share your observing experiences using Lockwood Optics or ask questions.

I expect posts to be relevant and civil. Debate is fine, but flaming, arguments, thread hijacking, advertising competing or unrelated products, etc., will prompt me to take action. Play nice. Keep it on topic. Mirror making is not covered here because I am simply too busy.

Lockwood Custom Optics makes optics for Newtonian and Cassegrain telescopes, specializing in large (up to 60") and fast (down to F/2) optics and systems made from monolithic and cast cellular blanks.

I specialize in large, thin, fast, accurately corrected, smooth optics that are excellent figures of revolution. I have significant experience with lightweight cast cellular blanks. A list of my commercial clients is here, and page showing some of my notable projects can be found here.

The photo shows a 50" f/4.0 mirror that was successfully tested (uncoated) in the telescope built by the Astronomical Research Institute. It is currently being used for for measurements of asteroids and near-Earth objects (NEOs), and other research.

A 32" f/2.8 was recently completed, as was a 45" f/3.75. A 40" f/3.7 Cassegrain primary is in process currently. Work on smaller mirrors is, of course, ongoing as well.
