I've had cloudy skies for quite some time and COVID isn't exactly encouraging me to go anywhere so out of sheer boredom I've resorted to cleaning up my astronomy odds & ends. I've accumulated a lot of parts whose origin has been lost to the mists of time and that includes some really random adapters. We all have the normal 2"- 1.25" adapters lying around and maybe some T2 stuff, but I'm curious what kind of unusual adapters are out there? Who knows, maybe someday someone will be looking for just that part that's nowhere to be found...Here are the oddballs that showed up in my inventory:
M68 male to M69 male
M69 x 30mm extender
M75 male to M68 female
M43 female to T2 female
What unusual stuff do you have lying around?
