I understand that the optically active element of the VIP-Barlow is the 2.6x glass-path-corrector lens referenced "4C" in the T2 system. Is that correct ? If not, Is the active element for sale alone ?

Hi: I purchased an Explore Scientific 82° 30 mm Eyepiece and am looking for a good Barlow. After doing a lot of research I discovered the VIP. I love how versatile it is! However, this eyepiece is a 2” behemoth (weighs a kilo), so I was wondering if the VIP is a good choice for this application? Thanks!

Hello: I just buy a baader vip Barlow. I have used it with 1,25” connection (in scope and camera). Results are perfect. Congrats for the product
I would like to use now in a 2” scope and in a reflex camera and I don’t know how to do it.
Is there any schematic to see the way to do it.
On the other hand, I would like to know the explanation about modules of the Barlow. On instructions included in the box, I don’t have in a clear way utilities of each module.
Thank you in advance for your help

Mine is not really a question, but I would like to offer my feedback regarding the configuration I use all the time for visual work:

(1) 2-to-1.25 reducer
(2) 15mm spacer ring
(3) 2" nosepiece (# 2408150)
(4) Baader VIP element housing cell
(5) Baader M43a x 0.75 / T-2a Adapter (# 2458199).

In particular, (4) is mounted on (5), and (5) is screwed at the bottom of (3) via T2 connection.

Advantages of this configuration for visual use are:
(1) the change in focus position when the VIP is used or removed is minor. Also, adding spacers does not change the focus position much
(2) it is more solid, as the connection with the focuser is via 2"
(3) the barlow can be used with refractor diagonals in 2" without hitting the mirror or prism.

Thanks for making such a wonderful tool.

Can this system be integrated into a M42 screw-system layout? Like male to camera, and female to SCT adapter

I am trying to figure out the magnification of the VIP Barlow when using with my Morpheus 17.5mm eyepiece. My scope is an 8" f/5.9 Dobsonian, 1200mm f/l/
