The first one is a Gitzo G106, with a Takahashi TG-SP II, Borg 45ED II. Coronado SM40/BF10 is used, and a DMK31AF03 is used for imaging. The PST etalon module can be placed in front of the BF10 for narrower bandwidth.
Next is a C5/PST based system. The tripod is a Gitzo G1415, with a Meade LXD55 mount, the scope is a Celestron C5. A Cheapy-ERF is placed in the front of the C5, a PST etalon and a BF10 is used at the rear port. Again, a DMK31AF03 is used for imaging.
