I have had mine like this for 3 years and no problems. I did install a light Mon, 14 Dec 2009 14:51:09 GMT Jim Bessette http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1684 http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1684 Thanks Steve, I ended up buying an even larger power supply (Samlex 1235M - 30A). I hooked it up briefly and it worked fine. I watched the meters while Sun, 13 Dec 2009 19:10:43 GMT nelsonscientificsca http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1683 http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1683 ... I have a Pyramid PS15KX 10A 13.8-Volt Power Supply that I use for my Gemini system. http://tinyurl.com/yabz839 I was wondering if I could simply use the Fri, 27 Nov 2009 23:28:37 GMT Douglas B. George http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1682 http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1682 ... The power supply has to hold up the voltage during motor startup, where inrush currents of many amps (10 or 15) can easily occur. If it doesn't hold up Fri, 27 Nov 2009 22:55:19 GMT Jim Bessette http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1681 http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1681 I'm tired of using a battery for my Maxdome (not II) rotation. I have a Maxdome purchased through Sirius in 2006. I guess it's not a Maxdome II.

George http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1678 http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1678 I originally had a C14 in my dome, which is a lot shorter than an RCOS. A 14" diameter telescope will work, but you have to line up the slit pretty Mon, 05 Oct 2009 10:24:56 GMT Torsten Daiber http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1677 http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1677 Hi, I can only second Dougs remarks. I do have a 0.34 m Hypergraph, about 1.15 m long, on an AP1200 inside the Home model. It is quite tight, and I too did set Sat, 03 Oct 2009 20:18:09 GMT cpjase http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1676 http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1676 It can be done. I believe Peter maybe a member of this list. He's the only one I'm aware of that has a 14.5" RC in a S2.3 dome - Sat, 03 Oct 2009 16:57:50 GMT michael redfern http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1675 http://tech.groups.yahoo.com/group/siriusobservatories_users/message/1675 For sure you need the 3.5m dome. I have a 60cm (16") telescope on a german mount (from astro optik) and it is a good fit into the 3.5m dome.

Hard to find 6 guys around here and then there are the injury/liability issues. I think I will have to go with the 12 foot Astro-Haven. It has Sat, 03 Oct 2009 02:47:09 GMT Douglas B.

The problem is, I cannot get a crane to the location to lift a 3.5. Anyone fit a
