Lee's Yawn

Posted By P. Lee Stock
Hey Kevin,

That is one good-looking low profile mirror platform (too low to call it a box). I just love these minimalist designs that have been popularized, if not actually started, by those ATM'ers up in the NW like Greg Babcock, Steve Vegos, Bruce Sayre, et. al. Probably a lot of those who attend the Oregon Star Party every year.

Your altitude bearings are particularly attractive. I assume the cage will rest between them and the whole tidy thing will fit into the back of your Honda CRV?

;^)

ATM refractors one more step

Posted By P. Lee Stock
That's beautiful! You really need to paint the OTA black--do not succumb to the temptation to paint it white (unless you do a deep lacquer pearlescent)!!

How much did you pay for the objective?

(Wow)

Fascinating, inexpensive software

Here's a shot flying in spaceship mode toward our local group of stars after having successfully hunted down the Milky Way. You can turn star, galaxy, planet labels on/off as well as a HUD indicator that helps you locate objects.

Delta 28-190 Bandsaw

Posted By P. Lee Stock
Hi Floyd,

No direct experience with it, but it is a 12" bandsaw from a company with a decent reputation and more HP than you'll find without spending around twice as much. There is that highly rated 12" 3-wheel bandsaw from Grizzly that costs about the same, but it is a benchtop model and I'm sure the HP is less--probably 1/4 to 1/3 HP. If it's in great condition, I'd say go for it. See if they'll sell it for $125, in which case you'd have a great deal.

I *just* started to love refractors...

More aesthetics feedback (probably unwanted, but here goes... ;^)

I know your rocker boxes are a simple and rather elegant engineering solution, but my eyes are trained to dobs with square rockers. I'd like to see an option where you could have a SS more square in shape on the bottom. Probably would only need a couple extra pieces of tubing or so, but would look more substantial. I admit it would be purely aesthetic, not necessarily any better, and perhaps only preferred by a few people like me. Just thought I'd share.

Bungee Tension

Posted By P. Lee Stock
Hey, that's a good idea. Very simple to integrate and looks easy to make adjustable if desired.

Best 1.25" focuser?

Posted By P. Lee Stock
Crayford or helical?

Of the helical variety, I really have enjoyed using the Kineoptics 2" focusers, the HC-2. I understand they offer a 1.25" version now, the HC-1. If it performs like the HC-2, it is a winner.

JMI sells a 1.25" Crayford, the Mini-2.

My experience with JMI focusers is hit-and-miss. Tool marks from machining sometimes inhibit smooth movement of the drawtube. I've had some that were great, others not so great. One was terrible. I expect the Mini-2 series would be similar.
