Dean,
 
Nice image, indeed.  I've used the "average" and "median" combine methods in
Registar, but I sure like the "blend" in PW better, since it adds depth and
detail while reducing grain.  I don't think with E-200 that you need *seven*
images just to reduce grain, though - man, that's really stacking!

Tony,

I've been using the Tak E-160 for 3.5 years, and haven't ever had problems
with flexure.  I know that Chuck Vaughn reported flexure issues with his
E-200, but I've never heard of anyone having trouble with the 160.  The
scope is very compact and rigidly built.  My rig, which is very similar to
Dean's is shown here:
