John, that backs up my own observations with science, thanks a lot!

Better that old people should die of talk than to have young people die in war.

You're welcome Paul. There are dozens of 'rules' and 'laws' but those four and the observation that the atmospheric limit of seeing here in Kildare is almost never better than 200x (usually less) are the most useful things that I've learned.

A high-power eyepiece will probably get very little use (compared to low to middle powers due to our conditions.)
I've found the most useful are around 28mm (25-30) 16mm (14-18) and 11 (9-12) If the 28 is a wide-angle so much the better.
I've a 7mm also, but it very rarely gets a chance.
Newcomers to astronomy tend to jump automatically to high-powers, but the usually dim views, poor image and fast transit speed of the image (if unguided) are usually very disappointing.
Many deep-sky objects also disappear as magnification is stepped up, whereas they're at their best at low to mid powers.

Hi redbeard,
I have the LXD 75 from lydl and i have an 18 mm celestron X-cel and a 12 mm coronado and i think their both great but tthe one i'd recommend is the celestron 18mm. It has a wide angle and is a good magnification for this telescope. I bought them from B&H , very reliable.

Are there any recommendations for high magnification eyepieces?

That's true Eamonn, but remember the scope under discussion only has a focal length of 762mm so even a 10mm eyepiece is only giving 76x magnification. For planetary use I find a 15mm with 3x barlow surprisingly usable even in our moist skies.
