Greatest eyepiece holder but beware
The Clicklock system is the greatest invention since sliced bread. Just be aware that some (longer) 2" eyepieces will vignette through a T2 opening. This would apply to the Baader 2" holder clicklock with M42 (t2) thread. I use my ES82 18...

Quality dust cap!
Quality aluminum dust cap. I bought several to keep some of my c-thread imaging gear protected from dust and dirt in the field. Blue Fireball makes great dust caps and adapters.

Perfect tool
This is an excellent 1.25" extender. I purchased the set of 0.5, 1.0, and 2 inch extenders. I use these for astrophotography and getting my Takahashi FS 60C 355mm, f/5.9 to focus with some of my legacy eyepieces.

It works to correct Crayford focuser.
My Crayford focuser was too short to reach focus. This worked to resolve that problem. It also gave me a shorter close focus distance. My close focus was 70 feet, now it is 30 feet.

It does what it says. My only "complaint" - cost. Adapters shouldn't really be more than a few dollars; after all, these are a thin ring of metal with threads. But other than that, works fine.

Excellent 3.5" extension tube for 2" eyepieces
This is a very nicely built extension tube for 2" eyepieces. For those looking for an extension tube for occasional "straight-through" viewing of astronomical subjects instead of using a 2" mirror diagonal, extenders which are onl...

Great Adapter
I use this to use my 2" eyepieces with a Coronado SolarmaxII scope that has a 1 1/4" diagonal. Works well and it is well made, Of course you wont get the full 2" eyepiece experience but you will get the comfort of using your favorite e...

Awesome Reducer
This is the second Fireball eyepiece reducer I've purchased from Agena Astro. It works well and the price point makes it a very good value. I have the more expensive BP reducer as well, but I find the Fireball easier to use. Highly recommended...

2" Blue Fireball Parfocalising Ring
I bought two... One to put on the nosepiece of my diagonal to get a bit of finger clearance around the lock knob at the back end of my refractor, the other for the nosepiece my photographic adapter, so I wouldn't need to rack the focuser so far ...

I attached it to an OAG to help with focusing. It made the OAG easier to use.
