This 2" Vernonscope 2.4X Dakin Barlow may be used with telescopes that accept 2 inch eyepieces. This Barlow is made with very high quality glass lens that gives sharp contrast. It holds a 2 inch eyepiece or 2" to 1.25" adapter with a brass compression ring, a screw insert, and a stainless steel set screw.
It also can be unscrewed at the center, and the bottom portion containing the Dakin Barlow lens screwed onto a standard 2 inch eyepiece, as shown with the Vernonscope 2 inch 48mm Brandon. When the bottom half is screwed directly into an eyepiece, the magnification is approximately 1.5X.
The Barlow was designed to be placed between the draw tube of a scope and a diagonal. In-travel will need to be longer when separated and screwed into an eyepiece.
This 2 inch 2.4X Dakin Barlow costs $289. (48mm Brandon eyepiece not included)
This Dakin Barlow is also excellent when used with the Vernonscope Master Birder spotting scope. See the BirdScope page for details.
