[Dboots (Duncan)]

I have recently re-kindled my interest in Astronomy and have purchased a 14" f4.5 Goto Dob. It came with 2 plossl eyepieces and I am looking to upgrade within a reasonable budget.

I have found a well looked after nagler type 1 4.8mm eyepiece for sale and was wondering 2 things:

1. is this suitable for a fast scope;
2. what would be a reasonable price for the second hand eyepiece.

The eyepiece is in good condition (in box etc).

Thanks
