Baader Q 2.25X Barlow Lens - 1.25"
The Classic Q-Barlow has been optically matched to the Baader Classic Eyepieces, and its 2.25X magnification gives a well spaced set of focal lengths. It's removable lens cell can also be unthreaded from the 1.25" barrel, and directly threaded onto any of the eyepieces to give 1.3X, further filling in the choice of focal lengths. Alternatively, it can be directly threaded onto the 1.25" barrel of the Q-Turret to give 2.25X with all 4 eyepieces.

Product QuestionsQuestion by: Astrofather on Nov 8, 2014 2:15:34 AMThank you for your question. I tried this on a William Optics binoviewer to see if it would thread on & it will not. This will likely be the same result if you were to try it on the Celestron binoviewers as I have tried threading this on many different eyepieces & it will not thread on to them.
TPO has a 1.25" barlow that has a thread off lens that will work with the binoviewers & most other 1.25" eyepieces.Answer by: Roderick (Admin) on Nov 18, 2014 12:16:59 PMHi, Would this barlow work excellently on a Baader Mark 1
zoom? If not, in your opinion is the Baader barlow made explicitly for there Mark 111 zoom worth the $30 extra over the
ES 1.25" telocentric? Thanks De LormeQuestion by: De Lorme on Feb 24, 2016 2:44:00 AMThis barlow should work fine in both the 2.25x and 1.3x configurations, though due to the Baader zoom eyepiece's complex design, you might get slightly different magnifications. This barlow is not a triplet apochromatic lens like the Hyperion Barlow, though, so it will likely not have as much contrast as the higher priced model. The ES model is a 4 lens teleextender designed around imaging, so it may also lose a bit of contrast to the triplet.Answer by: Chris Hendren (Admin) on Feb 25, 2016 3:21:00 PMQuestion by: mpgingdl on Nov 26, 2014 1:50:35 AMQuestion by: hunsingeruk on Dec 9, 2014 11:59:31 PMIt may work for shooting smaller objects, but there are some limitations on using this barlow with this configuration:
1) This is a 1.25" barlow so it will vignette the sensor on your DSLR. Even if you remove the lower lens system, you would need a 1.25" to T adapter to attach it to your camera.
2) barlows are not flat-field, so you may have some curvature in the field.
3) you will have to play with the spacing with the EdgeHD to find the best spacing - this may require using a 2" diagonal to hold the camera securely.Answer by: Chris (Admin) on Dec 10, 2014 8:10:52 AM
