Replacement eyecups

[Aquavit]

My Fujinon 7 x 50 marine bins are getting on a bit and the rubber has perished. Originally bought for boating use, I find them really nice glasses to scan the night sky with so would like to get them back in shape.

I've scoured the internet but can't seem to find anything, anyone got any ideas?

Hi Aquavit, found these on amazon:

https://www.amazon.co.uk/Field-Optics-Research-B002-Cups-Compact/dp/B00A45OHP0/ref=sr_1_1?crid=119D5WJXL1K00&keywords=Field+Optics+Research+Compact+Binocular+Retail+Packaging+Assy+EyeShield&qid=1676484107&sprefix=field+optics+research+compact+binocular+retail+packaging+assy+eyeshield%2Caps%2C214&sr=8-1

I don't know if they would help.

 

Edit: also found these for Fujinon 7 x 50:

Thanks Mick, neither of those options work for me, one is in the US and the Amazon option won't post to Hungary. I'm still working trying to track down Fujinon dealers in Europe, you would think a company of their size would have some sort of service network ........

If you like to DIY, serviceable rubber eyecups can be made from bicycle inner tube. I’ve made several.

Yes, I have heard about that fix, that's my option of last resort.

Sorry Aquavit, I only just noticed where you are living.

And yes a company of that size should have a service network.

Steve, my eyecups measure 42mm dia. how would your FOR eyecups fit, replace the existing or squeeze over? I have no idea of how to remove the existing ones either!

Will dig them out and check. 

However, these should fit https://www.baader-planetarium.co.uk/shop/baader-42-43mm-winged-rubber-eyecup-for-baader-hyperion-and-aspheric-eyepieces/

Just measured mine at 38mm. 🙁
