Hi Brian.

I recently bought a used Vixen 90mm f/9 fluorite and found that there were hazy spots between the 2 objective elements. Afraid they might be fungus, I contacted the Vixen North American folks and asked what I could do about lens cleaning. To make a long story short, I sent the scope back to Japan (through the NA rep). They not only cleaned the objective (& did a great job) but also collimated the scope and adjusted the focuser. The scope looked like new when they returned it.

The downside was the cost. At first, they estimated that it would be about $300 but it ended up costing about $480 (For the record, they gave me the updated cost before they sent the scope to Japan. I *really* wanted this particular scope to be OK so I went through with it...).

I don't know how recent economic changes have affected currency exchange rates but you could probably get a good cost estimate from Vixen. If you're interested in checking out this option for your Vixen-made scope, you could try contacting the fellow I spoke with, Mike Fowler: m.fowler@vixenoptics.com.

Hope this is useful,
John
