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!

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.

I have this VIP Barlow, along with all the Morpheus eyepieces. I would like to configure this Barlow so that I get 1.2x magnification, or as close to that as possible. As it comes out of the box, the lowest magnification with the Morpheus is 1.53x.

Baader has a lot of parts in their catalog, too many for a novice like me to sort through - is there anything I can acquire to convert or make the VIP element a 1.2x Barlow?

Thank you!

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

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/

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

Description

Details

VIP Barlowlinse Astro T2 System

Modular Barlow with 1¼" and 2" barrel

High quality optics with apochromatic characteristics, for magnifications of 2x and above

  • Optical design by Dr. Pudenz, who has also designed the Zeiss Abbe eyepieces
  • Modified by Roland Christen for US-American glasses
  • modular construction for visual and photographc (VIP) use
  • Fits into 1¼" and 2" focusers
  • Designed for 35mm-film (ideal for full-frame-DSLRs with 24x36mm-sensors)
  • Higher magnifications can be achieved easily by adding additional T-2 extension tubes
  • Focal length of barlow element: -65,5mm

The housing contains the following parts from the T-2™-System: #15/#29/#25a/#25a/#14

Attention: This is a 2x barlow lens. It has nothing to do the 2.6x glass-path-corrector lens that we offer exclusively for binocular viewers

The Baader Barlow lenses at a glance

With currently five different barlow lenses in Baader Planetarium's product range, it is not easy to keep track of which model fulfils which function best.

Fluorite Flatfield Converter (FFC) / 3x-8x (#2458200 , € 729.99)

90mm field of view also for medium format cameras - uncompromising quality even for extreme enlargements.

Focus gain: depending on configuration about 1.5-2.6cm

Carl Zeiss 1¼" Abbe Barlow lens 2x (#1603321 , € 477)

Legendary Zeiss quality for the common magnification range between 2x and 3x (with additional T-2 extensions). With T-2 connection for cameras or eyepiece clamps. The qualitatively equivalent solution to the Fluorite FFC when smaller field size and smaller post-magnification are desired.

Focus gain: About 3 cm

VIP 2x modular barlow lens, visual and photographic (#2406101 , € 228)

Versatile barlow lens for magnifications from 2x, for use with cameras (via T-2 thread) and eyepieces. Calculated for 35mm image diagonal (full format). With additional T-2 extensions it can also be used for slightly higher magnification factors.

Focus gain at 2x: Approx. 3.3 cm

Baader Q-Barlow 1.3x/ 2.25x (#2956185 , € 55)

Inexpensive and amazingly high quality Barlow lens for the lower magnification range: In addition to being used as a normal Barlow lens with eyepiece clamp (with factor 2.25x), the Barlow element can also be used as a negative lens group when screwed directly into (almost) all eyepiece sleeves or directly in front of a camera with 1.25" filter thread and then provides a lower magnification of approximately 1.3x. Ideal for adapting a modern planetary camera to the resolution of an already long focal length telescope. Prerequisite: There must be no other elements in the nose piece that would prevent the approximeately 13 mm long Q-Barlow lens group from being screwed in.

Focus gain at 2.25x: About 0.4 cm

Hyperion Zoom 2.25x Barlow lens (#2956180 , € 133) Specially designed for the Hyperion Zoom eyepiece, also fits the filter thread of other eyepieces.

With the included T-2 adapter, it can also be used directly on cameras; provides about 2.7x at 55mm working distance and about 2.3x at 25mm.

Focus gain: About 1.1 cm
