- Holds 1.25" and 2" Eyepieces
The 2.5x Luminos 2" Barlow Lens from Celestron extends the effective focal length of an optical tube by 2.5x. This telescope accessory features a fully multicoated optical path with four lens elements designed to improve color fidelity and transmit a field of view that is flat from center to edge. The eyepiece holder is threaded to accept 2" eyepiece filters and will accommodate 1.25" and 2" eyepieces; brass compression rings secure the eyepiece without damaging the barrel's finish. The aluminum housing is finished with an anodized hard coat for enhanced scratch and corrosion resistance.

Which is better, the Televue 2X Barlow or this ...
Which is better, the Televue 2X Barlow or this Luminos 2X? Anyone have experience with both of these?
I have a 2x 1.25 Barlow as well as this, but when I use a 1.25 eyepiece in this with the adapter I cannot tell the difference, they are both near perfect. My light meter says there is a 4% loss of light with both Barlows. You wouldn't notice that at all, maybe a camera would, but not even an eye with an infinite focus lens from cataract surgery. I cannot speak about a 2" Tele Vue Barlow because I haven't used one.

question
Will this work in a XT8 with 2 eye pieces 32mm and up? (lower) Will the XT8 have enough back focus for this?
@Marc TThanks Marc for the response and I apologize for thanking you so late.When I asked this the product that was on my mind was the Baader Hyperion Mark-III Zoom. I don't have a clue why I asked this about this Barlow, old and senile, other than I had planned to use this with the Baader. I did order this and the Baader Zoom. My Luminos 2.5x is actual APO and even said so on the box. I was pleasantly surprised with this. Has been cloudy since arrival so no chance to play with yet.Thanks again for your help...
