Astromart Article: How do I choose the best Eyepiece?
Michael Covington highlights the key issues you should consider when looking to purchase that eyepiece for either your spotting scope or telescope.
(1) 'The magnification should be high enough to show most, if not all, of the fine detail that the telescope picks up, so you can view planets and double stars.
(2) The magnification should be low enough to show faint nebulae and galaxies well.
(3) The field of view should be wide enough that a computerized ?go-to? telescope will generally get objects within it.
(4) The eyepiece should bring out the best in the human eye, whatever that means.'
