Seeing was not optimal (2-3 arcseconds at best) but I had time and no clouds.

 

Trying out my SMII 90 DS and I'm still learning the tuning and focusing issues.  I've added a motor to "automate" the helical focuser and am researching ideas to automate the DS etalon tuning.  My biggest problem is with the "slop" of the second draw tube after the focuser.  It being 1.25" doesn't help either.  I see a focuser upgrade in my future!

 

The three wavelengths are Ha through the SMII, Ca K II is with a Lunt Ca w/1200 blocking filter on a 100 mm f/7 masked to 73mm and with a 2.5X powermate.  The "white light" is with a Lunt 2" wedge and red ccd filter with the 100 mm f/7.  Thanks for looking.

Tried to do a full disk which is not ideal for a 174 sensor and the SMII.  I need some more real estate. Like a 183 chip.
