This camera was bought about 8 years ago to try out Afocal astronomy imaging. I made adapters to fit a standard possl 26mm lens and a 2" lens. They work well but I lost interest.
I procured the serial cable to supplement the USB one supplied and special software to drive it.
It comes with the manual, battery charger, AC supply, Nikon Disks and a SD card with the krincam programs.
The battery needs replacing but they are available on ebay for as little as $11.00
The picture of Saturn was a trial on a LX200 12" with a 26mm lens
