A Barlow lens is an optical accessory used in telescopes to increase the effective focal length of the telescope. This results in an increase in magnification without changing the eyepiece. Here are some general features you might find in a Celestron 2x Barlow from the Ultima SV Series:
-
Magnification: A 2x Barlow lens, as the name suggests, doubles the magnification of the telescope when used in conjunction with an eyepiece.
-
Ultima SV Series: Celestron's Ultima SV Series is known for its high-quality optics and construction. This series often features fully multi-coated optics to enhance light transmission and reduce reflections.
-
Compatibility: Barlow lenses are typically designed to be compatible with 1.25-inch and/or 2-inch eyepieces, depending on the model. It's important to ensure that the Barlow is compatible with the size of the eyepieces you intend to use.
-
Construction: The construction of Celestron Barlow lenses often includes quality materials for durability. Some may have a threaded barrel for secure attachment to the telescope's focuser, and they might also include a set screw to hold eyepieces firmly in place.
-
Threaded for Filters: Some Barlow lenses have a threaded barrel that allows the attachment of 1.25-inch filters. This can be useful for adding color filters or other specialty filters to enhance your observations.
-
Multi-Coated Optics: Multi-coated optics help improve light transmission and contrast, resulting in clearer and brighter views.
