Product Questions

Sort by ASC
Are the BBHS coatings easy to clean? Do the coatings have a life comparable to your dielectric coatings? Do the coatings degrade over time and at what rate? Is there a difference in performance between your dielectric diagonal and the BBHS one, what are the differences and are they significant or very slight? I own an early Televue APO 4 inch refractor.

I recently purchased one of your star diagonals. It is the T-2 BBHS Star Diagonal #2456103. I have read on your website that the optical path length is 43mm. However, I do not know the reference points for that measurement. For my star diagonal, do you have a diagram similar to the one in the link below? https://www.baader-planetarium.com/en/blog/optical-tube-lengths-of-2-clicklock-and-bbhs-mirror-diagonals/
Or, can you please describe to me where the optical path begins and ends on the diagonal body?
I need this information so I can accurately determine and measure backfocus distance.
Thank you,
John L

In regards to this style of diagonal, please clarify T-2 fitting?..
Are the threads (standard) for say a 2inch telescope eyepiece that could directly attach to this unit from the bottom barrel of it? Yes or no? .if not what is the diameter/threading of a T-2 fitting?
Thanks Dennis
