Hi Bob,
Nice pool, where's the Pina Colada ?
The eyepiece you are looking at is not exactly the right one but should work ok. One important feature to look at is the field number (FN) and although I can't be sure this one may be 18. The field number tells what the field of view diameter will be or, how wide the field is. A FN of 18 will give a field of 1.8mm when using the 10X objective. If you are interested I may be able to help you with this quest.
