I got this question from a reader and I thought I’d post it here as well in case it is helpful to anyone else:
I recently bought a Meade 285 at a Thrift Shop. It is missing the eyepiece. Could you provide me any specifications (i.e. diameters) or supply sources for replacement parts? I stumbled across your blog with searching. Thanks for any info you can provide.
Here is my response and photos to help with the description:
If you have the angled mirror pieces and everything and you just need the eyepiece itself, you can buy a wide variety that will work. You can buy any of the 1.25″ barrel eyepieces, this is the most common type as well.
The physical diameter of the bottom of the chrome collar is 1.50″ but the eyepiece barrel itself is 1.25″. I’ve attached photos showing the eyepiece dimensions for the ones that came with my telescope, they are the Meade MH9mm and Meade MA25mm.
