There are a couple of things a guy can easily do to improve the ES truss dob.  To better illustrate these ideas, I put together a YouTube video on Dakota Starry Nights that shows how to increase contrast as well as optimizing it for night vision, among other things. Clear Skies

Great stuff.

 

Loved the "red pill" solution for getting the trusses to hold still.

 

I've been pondering how to create a light shield for the UTA on my ES 10" truss dob too, so what you did was interesting. I may try a similar rolled material, but perhaps less fibrous, and try using glued hook-and-loop fasteners to adhere it around the UTA interior (or exterior, not sure yet).

 

Thanks for the ideas!

Dana, I've recently came across this material that may suite your needs for the light shield: "Easy Bagger Lawn & Yard Bag Holder" available at dept stores like Walmart or Amazon.  It's essentially a thin black plastic sleeve that fits into a garbage bag to keep it open for easy filling.  May be worth a look.

 

And thank guys.  I'm glad folks are finding the video useful.smile.gif

I'll check that out, thanks. Perhaps it's something that can be trimmed to the correct diameter, and then to a height about double the UTA's. I have a shroud arriving tomorrow from Shrouds by Heather, need to see how that attaches to the UTA first.
