Hi, question for people. I have an Orion long tube 120mm refractor I have had close to 20 years. Nothing special, achromatic, but kinda a good workhorse for viewing planets and such, and still like it. However I wondered if it was my eyes or if indeed the views weren't quite as good. Looking closely at the primary under lights, it looks like there is a haze on the inside of the glass. I am attaching a photo where bright lights make it pronounced.
Should I some how disassemble the refractor to be able to clean the other side of the glass? I took a quick look at it, and don't see any clear cut way to do this. Anyone have an idea? Is it even an issue? Thanks in advance for advice and suggestions.
