It doesn't look like anyone has posted this, but I thought it might be of interest. ZWO is a company that produces dedicated astro cameras. They started mostly in planetary imaging cameras (i.e. small sensor, high-frame-rate), but they just announced 4 new cameras based on an M43 sensor - I *think* it's the Panasonic sensor from the E-M1 but that's not confirmed. product link: New products Archives - ZWO ASI The 4 units are Color/Mono and cooled/uncooled. Additionally, they have an adapter allowing the use of M43 lenses with the camera - no electronic control so you'd be limited to manual/adapted lenses, but still a cool idea. I'm planning on getting the adapter to use with my ASI224 and my Canon FD400/4.5. The prices aren't bad, but definitely are out of the impulse-buy category. Starting at 699 for the uncooled color version up to ~$1200 for the cooled mono version.
