For example, a 1,25x or 1,70 GPC on top of the 1,7x newtonian GPC with a Mark V binoviewer. That would give a nice flexibility.
The 2.6x glasspath-corrector is solely designed to provide the necessary backfocus for using binoviewers in conjunction with newtonian telescopes and refractor telescopes. For correcting for the huge amount of glass in our Mark V giant binoviewer (# 2456410) - and likewise in the newly designed Maxbright Mark II binoviewer that is still under preparation at this time.
Both lens elements of the Baader 2x VIP-Barlow (# 2406101) and the 2.6x glasspath-corrector (# 2456317) do look quite similar when inspecting them by eye only (they use the same housing) - and we are very sorry that through the years this is always again creating confusion in the forums. However - we always again reiterate that the two products are not the same lenses and cannot be used for serving a dual purpose.
In case you were ordering the 2.6x glasspath-corrector and would use this product as a 2x barlow lens, you would find out that it creates severe chromatic errors if used in this (wrong) mode. The same accounts if trying to use the 2x VIP-barlow-lens as glasspath-corrector in conjunction with a binoviewer - you would see color error and conclude that the lens were faulty.
We never said that these two products may be used for the other purpose, but always again people look at them and conclude they were the same - which definitely is not the case. Both products work excellent if used for their specific purpose. But since they repeatedly are being (ab)used in either/or configuration, some people concluded both designs were flawed. Again - this definitely is not the case.
Thanks for purchasing the VIP-Barlow if you want a barlow lens. We are sorry but the barlow-element alone is not available. If you intend to use a barlow element only that readily threads into regular 1 1/4" filter threads, we do recommend our Q-Barlow 2.25x Link (# 2956185).
