"PerfectStar" Focus Controller

Astro photographers all know that perfect focusing is both essential and difficult. A motorized focuser is a big help because it allows finer control while avoiding the vibrations typically induced by turning a focus knob by hand. However, simple DC motor systems cannot provide enough precision and absolute positioning systems using stepper or servo motors are usually very…

Still Here

Hi Trevor,

Yep, still around. Got an 11" celestron and cgem mount to go with the EQ-G and 70 and 127 mm scopes.

In preparation for the star party this weekend, tonight I didn't break out the imaging gear which I've been testing for the past few nights, just the Dob (16" Lightbridge). Drinking in great views of…

The Skies Are Back!

After a solid 8 months of horrible skies (and an occasional decent sky of which I was working or some such thing) I finally got out to test my gear changes and I'm happy to say that I'm very pleased with the results.

The Atlas w/Vixen ED03s and ZenithStar 66 Guider

The Atlas was trouble from the beginning. I didn't expect that. I had (and still have to a degree) issues with the altitude adjustment. It's tight, it slips, the tongue inside is…
