The Apollo way -

Here ye Here ye. I present thee with a filter ring to please and heed something you may need.

Nothing but over the counter parts were used here. Nothing was measured, and only the slightest bit of effort was used.

Total time of life wasted, a whole 13 minutes. Now lets dance :hamster:

parts used.

This is the black, 2" nosepiece you see. The male end, has 46mm internal female threads and male 48mm threads.

-------------------------
This is the part which you see in the drill press which had its perimeter edge milled away. After milling, the part will fit inside a standard 48mm filter holder. You must use a fine thread cutter on the inside to strip away .6mm ; to allow 1.25" filters to adapt. (they are only sized to 28mm)

I also modified some of these adapters so they fit inside the 2" blue fireball adapter, I milled them on the drill press at an angle with a thread cutter so that it can only fit inside at an angle (tilted). I used a drill to place two dimples on one side , so it can be easily turned with a spanner or tweezers when mounting.

The 46mm male threads to the female back end of the blue fireball adapter with out modification..

You can see how both of these are attached to the blue fireball adapter, in the first and second photo..

------------------------

This part, is what I used used to cover up the 46mm adapter which was edge milled, it also extends the male threads.

-----------------------------------------
This part you see in photo six on the blue fireball 2" female thread, it covers everything up inside while allowing additional 1.25" thread for another filter.

I also milled a couple of these parts so they can fit deep inside the Antares 2" eyepiece barrel, This is also the part you see tilted in the very last photo.

this is the 2" eyepiece adapter, pretty much anyone you have will work just make sure it has female 48mm threads..

This is the ultraviolet barlow, which you see in the first photo ; i mounted this to the 46mm end of the blue fireball adapter.
