Makes a real difference
Bought this for a Explore Scientific ED102-FCD100 for the purposes of astrophotography and specifically planets such as Saturn & Jupiter. A major difference in imaging over a 2x barlow that has been used in the past. Image is magnified and still ...

Better than a Telescope's Pack-In
This is much better in build and optical quality than what you would get included in a Telecope Package. Definitely replace the one you got with your scope with this one.

Excellent barlow
Nice price for a quality 2" Barlow. I like the fact I can unscrew the lens from the Barlow tube and screw it into my 2" eyepieces. Keep up the great work!

Clear optics!
Great barlow for astrophotography. Clear optics, great coma correction, and very little/if any chromatic aberration.

Versatile barlow
I have only used 2.7 so far. excellent optics and clear views are possible with this barlow. And a second one to boot if your telescope can handle it. I have yet to explore the true value of this barlow.

Lightweight, clear focal extender
This focal extender is somewhat smaller and lighter that I would have guessed for a 5x. I see no obvious problems with the light being passed through it. This extender is too powerful for my telescope (130 mm reflector) with most eyepieces, but is e...

Good so far
When paired with a few of my eyepieces I have found it to work well, I have only had one clear night with it so far. It is very compact for what it is and a good price point.

Excellent value!
I compared the GSO 2.5x apo barlow to a TeleVue 2x I had. First, this barlow functions as a 2.1x barlow, not a 2.5x. In any event, on Almach, the beautiful pair was easily separated in my 17mm Sterling Plossl and looked simply beautiful, orange prima...

A Must for Planetary Imaging with shorter focal lengths
So much better for planetary imaging that a barlow. Why? You can place this anywhere in the optical train without complicating your required backfocus.

No Plastic Here
Was surprised by the high quality and all-metal, heavy-duty construction of the slotted 2" casing with it's matched-set 1.25 adapter. Excellent large ED Barlow. I am well pleased with it after use in both my Bresser AR 152L/1200 and Exp Sci...
