Hi all, i've trying a new mirror see on: http://perso.orange.fr/yves.lhoumeau/astronomie/diffusion/animation/planetarium/spheric/etude1.htm sorry, for the...
what a great idea. My school boy French was enough to let me figure the idea is to use a lens scavenged from a photocopier to narrow the focus so it can fit on...
Huh, that is an intriguing idea. I have a million of those glass bulbs lying around in the garage. Bet I could pick up an old photocopier from a nearby...
I don't know that it'll be of help to you since you've already ordered - but I'd recommend to others who are looking in to fabrics to think about theatrical...
Just thinking some more about this. I wonder how hard it would be to put this setup into a single system? ie, a case of some sort that incorporates all three...
... Patenting is the opposite of freely sharing. It might be justified in cases where huge amounts of money have been spent for inventing ingenious stuff. I am...
Patenting is patently not possible (sorry, lousy pun) There is no new concept or technique involved. Anyway, what I like about the spherical mirror set-up is...
Not to mention it is extremely expensive. Around $10,000 - $25,000, which usually makes it unrealistic for the little guy, in the case of a market as small as...

I had been looking at the Starland going, where did THIS come from, thanks for the info Ken! Im trying to contact him to get more info for HPA and the online...
Doug and Gare I think you get what you pay for. I have not had a chance to see how the cheaper projector performs, but it has been reviewed in detail on the...
Gare I have not modified the Auriga mount. It is a very simple and practical design. If I were to modify it, I would come up with a latitude adjustment. ...
To All: Yeah I've both the karakuri one that Ron Walker reviewed (the owner Aaron generously sent me one too), and the Lawrence Hall one, Ken hits the nail on...
Gare (and anybody else that's interested) I added pictures of the Ed Albin built "Auriga" dodecahedron pinhole projector to the photos section of this Yahoo...
Will go see thanks Ken, I've emailed Ed a couple times and he seems like a great guy! gare the home planetarium association www.planetariumsathome.com ... ...
thanks, that is a great suggestion. My cloth arrived today. Whoa, 90 yards of canvas is heavy. 109 lbs. Now, to begin sewing. I will let you know how it...
Hi, been lurking for a while but now I have a real question. We have an aging starlab projector we're going to start using for shows in a couple of weeks. ...
Just an update from the other (Ron Walkers) board, I think the two major small planetarium boards have different reader bases, we are attempting to develop a...
I have a large dome Starlab that I have been using at a time share resort. I have also built a console to control lights, projectors, etc. I am interested in...
