I finally got around to processing all my first light images with my 60 mm Lunt double stack.  I definitely have room for improvement in getting better tuning in this mode, so if anyone has some suggestions, I am all ears!  In any case, I felt like the double-stack lived up to its billing revealing far more surface detail than the single stack configuration.

Nice shots!  It appears your tuning is spot on but posting a full disk in grayscale without inverting the disk and with a slightly lighter bit of processing makes it easier to see how the tuning really is for comments.

Those are some stunning images INMA.  Extremely good results particularly in light it was first light.  I do agree with Warren, a b&w is kind of like the token fulldisk and does shed light on information that gets convoluted in processing.

High David,

 

Warren and Chuck are right; but even so, converting your FD image above to greyscale reveals your have some tuning and sweet spot issues:

The former you can fix easily, the latter, not so easily - and remember double staking and imaging will make sweet spots really obvious...

 

See my discussion related to similar issues with Chuck's DS system here.
