Eye Pieces.

As a newcomer to the hobby I have recently purchased a celstron 114GT.
It arrived with 2 eye pieces 10mm and 25mm.
Iam thinking of buying a 4mm would this be alright for this 4.5" telescope?
Many Thanks,
John.

No. Too much power.

It seems, the following set of eyepieces is optimal for your scope:
6.3 mm, 10 mm, 16 mm, 27 mm, 43 mm. You have 10 and 25, so at first it
is better for you to get 6.3 and 40-42, then something like 16-17 to
collect full set.

Exactly why are these optimal? Since the Nextstar 114 GT has a 1.25 inch
focuser, 40-42 mm will have the same True Field of View as 32mm, for the vast
majority of situations, the 32 will provide better views than the 40-42mm
eyepiece. Also a 32mm doubles with a barlow to a 16 which is a nice.

For a beginner (like I am) with a new 114GT, I'd suggest the Celestron
eyepiece kit. For about $100 to $130 (I paid $104), you get five Plossl
eyepieces, a 2X Barlow, an aluminum clad and foam filled case, and seven
filters to play with.

The 32 mm eyepiece in my kit is excellent, as are the 15 and 9. The 4 mm
eyepiece in the kit is not really usable with a 114GT (it's intended for
wide field scopes like the NexStar 80). I use the 6 mm only rarely. Of
the two eyepieces (SMAs IIRC) that come with the 114GT, my 25mm is OK,
but the 10 isn't too hot. I've found the Barlow in the kit to be OK for
my purposes, but others in the NexStar group (on Yahoo Groups) say there
are better quality ones out there. I've used the Moon filter more than
any others, but YMMV.

Supposedly the Meade eyepiece kit marketed a few months ago has better
quality Plossl eyepieces than the Celestron one, but I have no
experience with them.

Good idea.
