Comments about GSO GSO 1.25" 2x Achromatic Barlow Lens:
I am sorry for my English...
It is a very usable barlow: like 2x, like about 1,5x and like corrector for binoviewer about 2,6X.
With only one object I have tripled my eyepieces! I have found a very good chromatic correction.
Comments about GSO GSO 1.25" 2x Achromatic Barlow Lens:
Great barlow. Love the fact it can be a 2x or 1.5x barlow. Like others, I find I screw the lens onto my eyepieces more than using it as a 2x. No issues viewing with this. The 2" will be next.
Comments about GSO GSO 1.25" 2x Achromatic Barlow Lens:
Great quality Barlow! I use it in combination with a 25mm @ 10 mm on a fast 5.9 1200mm Dobsonian and can tell you for the money Its impossible to beat.
Comments about GSO GSO 1.25" 2x Achromatic Barlow Lens:
I bought the barlow to increase the magnification of other GSO eyepieces I bought from Agena Astro, and it works like a charm. Im very pleased with it and that there is no dimming of the image when used with an eyepiece. My set is now larger thanks to this awesome inexpensive barlow. Highly recommend.
Comments about GSO GSO 1.25" 2x Achromatic Barlow Lens:
I wasnt expecting much from this barlow. Something of decent quality. The barlow is very tranparent. I can not see any degradation of the image through my set up. The removable bottom lens isnt a gimmick, its a very useful feature. Infact i use the bottom lens (stacked ontop of my filters) more then the complete barlow!
If your after a good barlow, and you dont want to spend hundreds, give this one a try!
