Rob, Surplus Shed sells Canadian Balsam and cementing lenses isn't too difficult. However, de-cementing a lens can be tricky, especially if a modern lens cement has been used. And the larger the lens, the greater the factor of difficulty. Your best bet may be contacting the distributor. On Jan 4, 2008 10:54 AM, Rob Ratkowski Photography <ratkwski@hawaii.rr.com> wrote:

Optimizing my Burgess refractor for solar viewing, I painted the edge of the lens. Wellllllllllllll, the solvent has migrated into the lens where it was cemented together to about 1" leaving black spots. Does anyone know who does lens recementing?? I haven't used the scope yet and I would expect some flaring and such from the black paint, but it's UGLY.
