Lumicon actually closed their doors in 2003.  The name was resurrected by entities who acquired the remaining inventory and there was quite a legal battle over the Lumicon name.  To this day I'm not sure if it's still settled.

I believe Farpoint wound up with it. I still have a nice Japanese-made 1.25” prism star diagonal that’s a Lumicon. It’s a nice diagonal. I’ve had it about 20 years. I also still have a couple of Lumicon planetary filters.

I don't know why someone did not take over making the tubes?  Maybe no money in it?  Seems good old tubes are not around to buy anymore. I always loved the Parks tubes.

Hi

I saw this thread about Parks and it brought back memories. I worked in the lab for about 4 years from 2000 to 2004.

 

Maurice hired me and started me in the grinding side of the lab. I eventually worked in the polishing and figuring side producing mostly 6” f/6 mirrors ready for aluminizing. 

 

I enjoyed the process from start to finish.

 

Regards

Did they make the tubes at the place when you worked there?

Not sure how one would get paint to stick inside of a long bare tube, no way to sand it by hand if it's longer than a persons arm.  I used a soft toilet bowl cleaner mop head to paint the inside of my Cave tube.  But for sanding you would have to rig up something for the long reach down the rabbit hole.

 

 

Get it sandblasted. Without paint on it, there's nothing preventing reuse of the abrasive, so the cost should be really cheap - under a hundred bucks.

I have a fantastic 9mm Parks branded plossl eyepiece(Nihon Seiko made) from the 1980's which I still use regularly in my 90mm f14 Maksutov.

Aside from my 10” f/5 newt, I also have a Parks 25mm Plossl that I use in my Lumicon Superfinder.  Strangely enough, I use a Lumicon 25mm crosshair eyepiece (Kellner?) in an Orion ST80 as a finder on my 6” refractor. Maybe I should swap the eyepieces to be consistent!

I still have my Lumicon narrowband filters. When my OIII filter delaminated I took it back and they gave me a new one. I still have the original UHC and H Beta filters. They all still work well.
