What plagues a NiMH battery is a Tue, 05 Jan 2010 03:47:26 GMT rbohnenstiehl http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1920 http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1920 Not sure about the cold and the battery. My E510 battery last me several hours in the cold. It could be the camera itself doesnt like the cold and something Sun, 03 Jan 2010 20:38:17 GMT j_minnerath http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1919 http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1919 I got the LBH-1 from B&H Photo. Radio Shack stores usually have a selection of chokes, I just picked out one that looked like it would fit over the wire I was Sun, 03 Jan 2010 20:23:28 GMT rich.shippee http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1918 http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1918 Thanks a lot for the info. Im going to try to build one as soon as I can. Where can the battery case be picked up? It would be nice if radio shack had that as Sun, 03 Jan 2010 20:06:46 GMT j_minnerath http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1917 http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1917 I looked through that thread at 4/3rds Photo again and there isn't really a photo of the whole power adapter. Since most of the Evolts don't have an external Wed, 30 Dec 2009 15:23:49 GMT j_minnerath http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1916 http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1916 Here's a lint to making a power adapter with the LBH-1 and a Radio Shack power brick. I tried different power supplies, but the RS works best.

I have looked at your photo's and I did see one thing that you talked about soldering the wires but it doesn't look like a Mon, 28 Dec 2009 14:22:27 GMT j_minnerath http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1914 http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1914 I don't have a web site. I have a small album here. It's at the last page in the "Photos". Also look at 3Dpans album. He's probably been able to do more with Mon, 28 Dec 2009 13:45:28 GMT Dave Brugger http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1913 http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1913 John, Would you please publish the web address of your WRS Observatory. I did a Google search and didn't find it. I am new to astrophotography and want to Mon, 28 Dec 2009 13:34:25 GMT j_minnerath http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1912 http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1912 Rich, To get away from the problem of batteries, make an adapter as I show in my album WRS Observatory. Also the plug that goes into the camera body is really Mon, 28 Dec 2009 03:46:26 GMT Dave Brugger http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1911 http://tech.groups.yahoo.com/group/Olympus_Digital_SLR_Astrophotography/message/1911 Metal nickel halide batteries do lose function in the cold. Perhaps the amperage output diminished to the point where it couldn't power the camera.

I use Olympus studio 2 to run my camera remotely and use the time lapse feature.
