Corona camera #3, Tamron 400mm/4 + Canon 5D2

On travel post-eclipse, will do composite when I get back home..

Mounted on counter-weight shaft of Takahashi EM100 mount (main scope is Takahashi FC100 800mm f8)

^^^ Tamron 400mm/4 lens on Takahashi 2-axis tangent assembly, (custom) mounted on Takahashi EM100 mount

2nd mount (Takahashi EM100), with left-to-right:

Tamron 400mm/4, Takahashi FC100 (800mm f8), Meade ETX 90 (1250mm f12.5)

Unfortunately, I had to ABANDON the Meade ETX.could NOT find the sun!? Turns out the mount-adapter was *loose*.. DUH!! I had 2nd laptop (2016 MacBook Air) to control the ETX for 2nd/3rd contact Baily's Beads ("burst mode")

NOTE:

The 400mm/4 & 800mm/8 bracket-sequences were done *manually* with remote shutter release cables. 

Just 1 day before I left:

Testing with SEM (Solar Eclipse Maestro) on MacBook Pro (2014) initially was fine -- both Canon 5D2 (for 800mm & 400mm) were able to be detected/fired by SEM. All of a sudden, the cameras simply COULD NOT be detected!? Flat out GAVE UP..
