We have a Hot New Product out now with our PST Focus Knobs which upgrade the existing focus knob of the Coronado PST. These knobs have recently been a popular discussion in the Cloudy Nights Solar Forum and are currently available for purchase at www.criterionmachine.com .

Need something a little more substantial to get a hold of when focusing your PST? Then this is just what you've been waiting for. At 1.125" in diameter this knob is over twice the size of the factory focus knob, affording you a finer focus, better feel, and greater ease of use when wearing gloves or if you have arthritis. This knob is easy to install and requires NO modification of the PST, it merely slides over the factory knob and is held in place with a set screw. This is a must have item for the Coronado PST! Contact us for further info or to make a purchase. The price is only; $20.00 ea. + S&H

Thank you for your interest! :jump:

I love mine. It really makes it easy to focus the PST. Should have been stock.

Mine just arrived today and I would concur. It's surprising sometimes how a small item like this can contribute to the viewing experience. Much less groping now as I look through the EP to find the focusser!

Hi Dewar,

Well there is that saying about big things comming in small pakages or that it is the small things that really matter, but with me I say the devil is in the details! But on any account thanks for the kind words.

Ps, 2 gorrillas really?

Yes, see www.gorilla-haven.org - I occasionally observe from inside the gorilla Habitat (after they're put away of course!!). :grin:

When I did own a PST that was one of the reasons I sold mine.It was somewhat difficult to use enjoyably.

I wish this was around then.Or perhaps I will give a PST another try,But ONLY if I am able to get one of your awesome new Upgraded Focusing Knobs.

I definitely love mine!

Had to make a modification in my hardcase foam for it to fit. :)

It was amazing to see just how big this is but it sure makes focusing much nicer now.
