Thanks, Tom. Since you will be using the Lunt, I feel more comfortable. 
I purchased the Lunt Wedge about 6(?) months ago. I called Lunt and made 
sure there would be no problem with a 5" refractor getting the wedge too 
hot and was told there would be no problem  I was uncertain about the 
claim of superiority (not by Lunt, but others) over the Thousand Oaks 
filter in detail that can be seen and so I also purchased it and 
compared the two. It does appear the Lunt has a slight edge over the 
Oaks. BTW, if anyone purchases a Thousand Oaks filter for a small 
refractor, start out putting a small amount of the felt on the inside of 
the aluminum housing. I made the mistake of putting too much and 
couldn't get the filter on the end of the telescope. I had a heck of a 
job working loose the felt (because of the adhesive back) with a cloth 
and rubbing alcohol.
