I just bought this eyepiece and noticed some black spots on the inside of the barrel. I think its just glue but I'm not sure. Anyone seen this? Its an explore scientific 82 30mm

Can you see them in the field of view?

Welcome!

Are you seeing black spots on the inside of the barrel wall or on the inside of the glass?

I'd say it's not uncommon to see an uneven finish inside the barrel of some oculars, but unless it's actually on the glass I wouldn't worry too much about it. Since the ES' are sealed, there's not a lot you can do about it except exchange it for another.

Hello fattystar and welcome to Cloudy Nights.

 

Where on the inside of the barrel are the spots? Behind the glass or on the threads?

The black spots he is referring to are on the barrel. Mildly intriguing, but really doesn’t matter.

My guess would be some moisture (for lack of a better term) spots on the barrel during the finishing; makes the paint vary in sheen.

 

If it doesn't hurt the view I would be conflicted as to return it; trouble of return vs. potentially diminished resale value.

The lenses are fine, you only can see the spots if you tilt the ep. I sent explore sci a message for their input. Its a nice eyepiece otherwise.

 

Update ES gave me a RMA for a return for a cleaning/repair, not sure about returning it. I just wanted a confirmation it was ok...hmm

To me looks like over sprayed paint

basically poor finished inside barrel

however this will do nothing to the view!
