Joe and Patrick - Thanks for the comments. It turns out the 1.5x Powermate isn't made anymore. Today I did a focus test chaining a 2.5x Powermate and with a nose mounted 0.5 1 1/4" focal reducer on an eyepiece. It seemed to yield about 1.25x to 1.5x but the scope did come to a focus. I didn't have time to do a test image today. Hopefully, that will better match the camera or have a wider in-focus travel length. The test had much lower resolution than the prevailing amateur high-end standard-of-practice using the 60mm Lunt Ha and Ka scopes. http://solardatabase.free.fr/tableau.php . At 2pm there was small prominence rising at the east-east-south limb. - Kurt
