Bresser EXPLORE SCIENTIFIC 52 LER Eyepiece 6,5mm Ar

High power eyepiece s (e.g. 3mm to 10mm) are used not only for obvious observations of  planets and double stars , but can be employed  for bright, compact deep sky objects.  Not only will the scale of an object like a planetary nebula or globular cluster be impressive as  it fills the eyepiece FOV , but  the background sky will be very dark  as the  contrast effect increases with added magnification , provided that the atmospheric seeing conditions are favorable enough to reveal a sharp image.  The 6.5mm  is a popular choice for a wide variety of telescopes, producing some of the highest magnification views that most astronomers will observe at.
