post a photo of your objective coating!

Post by TheSkyBurner » Wed Oct 31, 2018 3:05 am

I recently have concluded that the objective lens coating makes or breaks the scope at certain wavelengths. I am curious what your coatings look like on your wonderful scopes!

Please post a picture of your objective lens, angled so that the coating itself reflects the color directly into your camera.

Label your post with the brand and scope type you have!

Thank you to those who participate!

Ill get this color party started below. Its like a rainbow!

Apollo:
Here are a couple of coatings from my scopes.
TEC 10" f/20 Maksutov, and a hand picked 12" f/10 Meade LX200.
Both with very good optics.
Have most of my inside scope tubes covered with cork lininig aside of air fans.
Regards,
Eric.
