2" Advanced Convertible Barlow (BARADV)

Description Our Advanced Convertible Barlow has a unique design that provides several configurations to increase the focal length of your telescope. It was designed to match the characteristics of small and medium-sized CCD chips. It is also ideal for high-power visual observation and lunar-planetary-solar photography. This redesigned optic features a flatter field, allowing it to be used for deep-sky photography when increased magnification of smaller objects is desired. It can be used conventionally by inserting an eyepiece or a camera’s nosepiece into its 2" locking adapter.  Alternatively, the optic section can be separated from the 2" locking adapter and screwed directly into a camera’s faceplate, or threaded nosepiece, or extension tubes for a flexure-free fitting. It has both 42 mm and 48 mm threads for versatility. See system chart for configurations.
