Rich, you're absolutely right, and I feel like such a fool. When I wrote in my original post that the haze "appears" to be internal, I forgot to take into account that refractors refract and light bounces all over the place. It can be very deceiving. The overwhelming consensus was that I should send it to A-P, which would mean lifting the cell off the tube for the first time anyway. So today - wearing latex gloves - I did just that. I don't mind admitting I was a bit nervous.

Guess what? Rich was right. The haze is simply on the inside surface (inside the tube). I buttoned it all back up and have already gone online and ordered the Astro-Physics Optical Cleaning System. Considering the alternatives, it's a bargain at $48. A few careful swipes and it should be gone.

Please accept my apologies for being so dumb and not checking that first. You have my sincerest appreciation for being so helpful and understanding, and sharing your wisdom. My gratitude to all, and I'm sorry for wasting everyone's time. I think there's a saying, "there's no fool like a happy fool", and I'm a pretty happy fool right now. Thanks again.
