Nice Bernard. Looks like you are enjoying the 90hr-sw.
Thanks Dave,
Yep, pretty amazing lens. In combination with the sensor it is an amazing combo for this kind of shooting. Now I need to add spherical stitching to the mix for added fun!

I designed and had 3D printed a special bracket to mount a laptop battery below the H6D-100c back and it makes usage on the Arca in the field painless. The rotamount makes changes of orientatin easy too.
The only slight issue is that the back won't shoot when live vew is active. You need first to exit live view at least when the capture is triggered by the lens. They have a pinhole mode that adresses this, but subject movement becomes a problem I believe... anyway, more studying needed but happy so far.
Due to the nature of the subject I didn't even bother to do an LCC for the night shots. I had pretty big amounts of rise applied here, but no color cast is visible... well you could argue that the whole image is a huge color cast obviously.

Cheers,
Bernard
