Help me my celestron 20mm erecting eyepiece from my power seeker 127eq is blurry but it is completely clean. When I look in it up close it is blurry, but when I look in to it from afar it is clear. Please contact me at <private contact details removed>  or I can send photos of what the eye pieces look like.

I have a Celestron "PowerSeeker" 127EQ.  It also came with a 20mm erecting eyepiece, and both just like your own...

Oh, don't set that 4mm(250x) aside, or throw it away.  I snapped this shot of the Moon through it and the 127mm telescope...

The live view was much sharper than that, and riveting!

I don't like my own.  The view is too narrow for a 20mm, although you do get an erect, corrected image with the telescope.  Otherwise, it's hard as dried beans to find an alternative; shame, that.
