No big surprise as the DA300 is a very very very good lens.

Surprisingly low (5mx5m) resolution. Must be a long way out. > On 24/05/2023 15:39 Alan C <cole@lantic.net> wrote: > > > https://petapixel.com/2022/03/14/ricoh-installs-modified-300mm-f4-lens-on-japans-kitsune-satellite/?fbclid=IwAR0mq3UlLvUh5mFpBGfACX37YL-4PEnSH5H3bDaW3OArmGZlUNzoovzqJbw >

Approximately the same orbit as the ISS, average altitude 250 mi (400
km). It's probably a "low resolution", inexpensive image sensor.

According to the article it's a "cubesat" - modular (10cm modules), LOW
BUDGET platform for "citizen science" - high school kids (or college
students or hobby clubs or ...) can design them, assemble them and NASA
will haul them up to the ISS for launch.

KITSUNE = Kyutech standardized bus Imaging Technology System Utilizing
Networking and Electron content measurements

This is a 6U satellite, so it's the size of 6 - 10cm modules (30cm x
10cm x 20cm package) designed by Kyutech - Kyushu Institute of Technology
