Joe I drilled holes as close to the center of the mounting plate as the ribbing would permit and now the balance is much much better. I still need a few pounds at the front to balance things but this

I used a 300mm pentax f/4 6x7 lens for this shot. It is 3x20 minutes per filter ([SII], Halpha and [OIII]) unfortunately I only have one hour exposure for each filter but it is pretty obvious what

channel is if you would like to duplicate the emission lines as they occur in nature and place them in the right spot in the visible spectrum then you put Halpha in Red (656nm), you put [OIII] in

I've posted photos of this setup in the photo section under Mach1/Mewlon 250. Brian

Sorry for the plug on the AP list but you may want to check out my automation system, http://m1oasys.com as a solution to this issue. This very sophisticated and flexible observatory automation

Hi Konstantin, Thanks for the suggestion. The type of switch used is not important. There are mercury switches, reed relays, AC microswitches, etc. that will all work. The real issues are: 1) How to

Try to see if you can find an old home thermostat controller. Inside you will find a nice miniature mercury switch. Gedas http://gedas.cc www.w8bya.com

Paul, I used a digital amp meter and the slightest change in CW or OTA weight changed the amp reading. Read my comment in "Switched Power" post, luckily I have access to some great electrical

Hi Konstantin, Actually, "mercury switches" are almost impossible to find, at least in Canada, because of the ban on mercury due to it's toxicity. Perhaps some "ball bearing" based level sensor

Paul, I'm far from knowledgable about electrical circuits. I had one of our airplane mechanics explain the procedure to me, set up the amp meter and draw me a diagram. I can fax you that diagram,

Hello, I think it is not so important where the scope is pointed in the sky. The failure is only happening if the scope is going to point lower than the horizon. So what you need is a switch

Maybe Software Bisque would be willing to provide some insight. Frank

Hi, I am trying to devise a system to prevent the AP mount from driving the scope into the pier if the computer, etc system fails. There are multiple failure scenerios in an observatory where various
