I just received a Celestron 8-24mm zoom lens.

Is it normal to feel like I need to put my eye right on top of the EP?

 

I only bought this to get some idea of what range EP's to pair with my ES 102mm.

The Specifications webpage for that eyepiece (  https://www.celestro...m-zoom-eyepiece ) says that the "Eye Relief" is 15mm-18mm.  That's not that close.   Eyecrazy.gif

If your Celestron zoom is like my Meade zoom (and I think it is by the pictures), I think I know what you mean. I think the eyecup is too long. I get the best view with that thing folded down...it just seems to be in the way. If I have the eyecup up, then I have to place my head straight over it and farther out than I would like. It seems to blackout more easily too. 

 

Maybe folding it down will help you (if you haven’t already)?

I have that zoom and I never feel I have to press my eye to the lens.  However, as Erin says, the eye cup is there to help you place your eye at the proper position.  

 

I find it quite comfortable to use. 

 

What are you comparing it to?

That's what I thought.  Been working with it more, ok views now, just closer that my other EP's.

Just takes getting use to.  Tried the eye cup down.  Found it works better up, when you just feel the eye cup I am dead on.  Now if Jupiter would just get out of the tree.

Thanks

You can also take the eyecup off and put it back on upside down. Seems to give you a bit more room.
