I've been asked by my local makerspace to run a class on building a basic Dobsonian -- a parent/child sort of project. I'm sourcing material for 4.5" f/8 kit, but need an inexpensive, but serviceable eyepiece(s) for hopefully no more than $30. I'm trying to keep the total cost for each person to $200 for the build, so it may be a case of sending them home with a single, compromise e.p. -- I'm thinking a 10mm.
Obviously, 4.5" is a beginner project, and if anyone walks away from the class with a serious interest, they'll be upgrading and can get a better quality e.p. then.
TIA.
