Dear Sir,
I use a Baader T-2 prism diagonal with a 1,25" clicklock eyepiece adapter.If I insert the Zeiss Abbe barlow lens into this clicklock will this not hit the prism inside the diagonal? I ask because the 1.25" sleve of this barlow seems much longer than the 1.25" clicklock eyepiece adapter I use??
Thank you very much!
Best Regards

Do you know what the lens element to imaging plane distances are for 2x, 3x and 4x operation? Also the text says no loss of quality at 3x then elsewhere it says no loss of quality up to 4x. Is 4x okay or is that a misprint?
Thanks
Martin

Do you have any transmission information for this barlow in the 300-400nm range? The transmission curve shown suggests a very steep fall off. We wish to offer a 2x barlow for imaging Venus with the U filter and this may or may not be suitable.

I would like to know the clear aperture of this Barlow.
Additionally, if the sleeve containing the Barlow lens is used in place of the T2/1.25" nose piece of a MaxbrightII binoviewer, would this cause vignetting as the clear aperture of this Barlow looks small?
Thanks

I plan on using the Zeiss Barlow with a Takahashi Eyepiece Turret. This turret has a restriction on the length of the barrel that can inserted into the turret. This length should not exceed 31mm.
Appreciate it if you could let me know on the length of the barrel of the Zeiss Barlow.
Thanks,
Sabir
