2" extension tube was: Long 2" to 1.25" adapter
Orion has one. Type "extension" in the search field on their home page.
Joe "Del Johnson" wrote in message ... You could glue the two together and pretend that they are one piece. :-) Lumicon used to sell all sorts of tubes. Often these tubes were sold for the purpose of allowing for filters when using unthreaded eyepieces. You might try the second hand dealers. You could also buy a used 2" Barlow and remove the optical elements. Del Johnson "Tom Marshall" wrote in message om... Thanks Del. Yes I thought about that. But I'd prefer the long adapter. If I can't find one, I'll get an extension tube. BTW do you know a good source for 2" extension tubes? Thanks. Tom. "Del Johnson" wrote in message ... You could easily couple a 2" extender tube with a regular 2" to 1.25" adapter. Del Johnson "Tom Marshall" wrote in message om... Anybody know where I can get a long (about 2.5") 2" to 1.25" adapter threaded for 48mm filters. Alternatively, anyone know where I could have one of these machined from aluminum? Thanks. Tom. |

Thanks Del and Joe. I quess I wasn't clear. My application would
require an eyepiece barrel extension that would attach to the filter threads of the adapter I currently have. I think Televue makes one of these. I'll check that out. Thanks again. Tom.
