The 2X ED Big Barlow - 2-Inch Barrel by Third Planet Optics:
Are you interested in an excellent quality 2-inch Barlow lens without paying the big name prices? The Third Planet Optics 2X ED Barlow is for you. This premium Barlow is made of high quality materials, including Extra Low Dispersion (ED), fully multi-coated glass for higher contrast, sharper images.
Outstanding views aren't all the TPO 2-inch Barlow has to offer. By including a 1.25-inch adapter, now virtually all of your eyepieces can have double the magnifying power without sacrificing eye relief. Just think of how much more light a 2-inch Barlow would gather instead of a 1.25-inch!

Questions & AnswersAsk a Question
Is the barrel threaded to accept filters?
Michael, the TPO 2x Big Barlow is threaded to accept filters. We do have the barlow in stock. Thanks, Steve
Does the lower lens unscrew to be used at 1.5x magnification?
Yes, the unscrewed lens cell has an M48x0.75 2" filter thread and will thread into the bottom of 2" eyepieces. Doing this will give you approximately 1.5x magnification depending on the specific eyepiece used.
Is this a single element lens?
No, this barlow uses a 2 element ED doublet to change magnification while keeping chromatic Aberration well corrected.
