Offered is a camera/wheel/ filter system for photometry.  10 filters are included, and mounted in this assembly.
Sloan b' g' r' filters are mounted.
Bessel G, R, I,  filters are mounted.
All photometric filters were produced by Custom Scientific filter company.  Transmission graphs are included.
One 'dark frame' filter is included.
I have forgotten the other three filters.  I recall a yellow 'exoplanet-ish' filter is included. Possibly a deep red 25A filter present.  Possibly a light polution filter.  
The assemby includes an ZWO ASI1600MMGT Pro (cooled with 5 position internal filter wheel), a ZWO EFW 7 position for two inch filters, and the 10 filters.  This complete assemby was removed intact when I decommissioned my observatory recently.  Everything was working well.  This assembly allows a pass-through no-filter position.  
The black tape around the camera joint is not there to seal a light leak.  It is there because - why not?
The washer stack is balance weight fine adjustment.
