Where have these been all my life?Pros: Cons: Comments:
Perfect for capping of threaded together astrophotography gear. No chance of falling off like plastic caps. Very well engineered, no sticking of threads.

I needed some T2 end cap to protect the filter in my filter wheel while it's in storage to avoid dust getting in. This one worked perfectly. Another great product by Blue Fireball.

Tired of those dust bunnies? Add this to your kit and you'll be able to semi-seal your unit. Add a small amount of wax, "burnished" into the threads and it threads smoothly on.

I hate plastic plugs when I want to be sure dust can't get on my optics. I rub a little bit of candle wax onto the threads, buff it in, and not only does it help make threading nice and smooth, but it adds a bit more protection from dust.
This is a good product. Get it.

I've searched for sometime for this product and found it at agenaastro.com. I use it on the t-thread/EOS adapter on my Canon DSLR when I wish to leave the adapter on the cam and wish to protect the sensor area from dust and other foreign matter, which could be problematical.
