Quote:Don't waste your money on a 40mm 1.25" eyepiece. The 1.25" field stop makes eyepieces longer than 32mm mostly a waste of time.
Quote:There is one eyepiece that I would suggest that you invest in for your 125 and that you will love at first peek. The Televue Panoptic 24. It is expensive but once you try it in your 125, it will instantly become your favorite eyepiece and you won't have much desire to buy a whole bunch more eyepieces...
Quote:I really don't 100% agree with this statement. While both the 40mm and 32mm eyepieces will show about the same FOV (.9 degree) due to the 1.25" field stop restriction, the 40mm does have a larger exit pupil (2.7mm vs 2.1mm). Since the brightness of extended objects (galaxies and nebulae) is proportional to the square of the exit pupil, that would make these objects 1.6x brighter in the 40mm over 32mm eyepiece. That does make a difference when viewing the faint outer regions of extended objects. I see this all the time when using my 40mm eyepiece in my ETX-125.

Quote:It's true that the 24mm Panoptic gives about the largest field-of-view in my ETX-125 so why go with a longer focal length eyepiece to only get a brighter FOV and see less.
Quote:It takes an experienced deep-sky observer to know that the key to seeing more ... even in moderately light polluted skies ... is in the size of eyepiece exit pupil and not just its magnification ... only a rank beginner goes for the high power eyepiece, thinking he will see more.
