Hi Brian,

The image was taken by Pentax 67 and a 90mm/F2.8 lens at F3.5.
The film is E100S (push 1) and the exposure is 80min.  It was
taken on Mauna Kea, with excellent sky transparency.

The image I shown is only part of the fov of the 90mm lens.
I took nine images around Orion, with identical setups and 
under similar weather.  I plan to make a mosaic of winter 
constellations, similar to the one by Axel Mellinger, but
deeper and with higher resolution.

The post-processing is only half done and so far, is not very 
satisfying.  Unlike other prime-focus mosaics I took before, 
this one has many problems to solve.  I'm not sure when I can
finish this.

Cheers,

Wei-Hao
