Bresser EXPLORE SCIENTIFIC 52 LER Eyepiece 4,5mm 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 4.5mm is a popular choice for a wide variety of telescopes, producing some of the highest magnification views that most astronomers will observe at.
