Hello. Can this Hyperion Zoom 2.25x Barlow lens be used with any eyepiece -- say a 5 mm EP for higher magnification, given your zoom stops at 8 mm -- giving equally good results as with your Mark IV zoom, or would quality be compromised in that case? Thanks in advance.

When the barlow is used with the zoom eyepiece, can a 2-inch filter (or a 1-1/4 inch filter) be attached somehow?

Hello. I initially posted this question regarding the Mark IV zoom eyepiece but should have posted it in connection with the 2.25 Hyperion barlow (which I am now doing).

I recently purchased both the Hyperion Mark IV zoom and Hyperion 2.25 barlow and have a question regarding set-up.

While the box for the zoom suggests that the barlow is attached directly to the eyepiece (see caption "thread for Hyperion Barlow" and arrow pointing directly at the eyepiece), the manual (https://www.baader-planetarium.com/en/downloads/dl/file/id/356/product/3117/description_and_recommended_accessories_for_the_hyperion_universal_zoom_mark_iv.pdf) indicates at p. 11 that "the barlow is attached onto the 1¼" nosepiece" (i.e. nosepiece between eyepiece and barlow).

Could you please advise as to the correct set-up? Does it matter one way or the other (my preference would be not using the eyepiece but I am happy to do so if this will improve performance)?

Many thanks in advance for responding at your very earliest convenience. Your kind assistance is much appreciated.

Thank You!

I have a newton 130/900 on eq2 and I have to connect my DSLR Canon EOS 100D through Hyperion Barlow; because the focuser is cheap I want to screw the barlow to the focuser thread. Is there an adapter that allows to screw the thread of the Hyperion Barlow (Focuser 1.25") and allows him even to use the 1.25" filters?
