Are you considering buying a 40mm Plossl eyepiece ? Read on to find out why we would recommend going with the 32mm Plossls instead.
40mm Plossls vs 32mm PlosslsDate: 11 Jan 2010 If you're interested in a 40mm plossl eyepiece, read on. I would not recommend getting it, but go for the 32mm eyepiece instead. Here are two graphical representations of the views you will get. Simulating views of the Hyades cluster through an Orion ShortTube 80 (FL 400mm), the left one is the 32mm view, and the right is 40mm . Here are the 2 key differences.
The conclusion seems like a no-brainer to me :-) !!
Here are the
maths for those who are interested :
Here are some examples with telescopes of 600mm and 1900mm.

same amount of stars with both eyepieces, but the view will be bigger with the
32mm !! Joo Beng |
