Solved!

Thought I'd share some pics of the extra long (40mm) eyepiece caps that arrived today.

Case #1

I have a Lumicon 1.25" filter slider with a William Optics 2x Barlow nosepiece so I can achieve focus in my refractor. I want the Barlow to remain attached but it's narrower than 1.25" so normal caps just fall off. With the long eyepiece cap the problem is solved.

Case #2

For white light solar I use a Baader continuum filter and polarising filter stacked together and attached to a short extension tube. Again, they are slightly narrower than 1.25" so normal caps won't stay on. I'm now using the long eyepiece cap and no more problem!


Thanks to Stefan (Saturn488) for making these for me.
