A new company has made the leap into EAA and planetary cameras. A Chinese based company called Player One. They have some nice offerings which should be explored.
The two most appreciable benefits in their cameras is DDR3 256mb cache for uninterrupted data streaming that even works good in the USB 2.0 configuration (but is wired for USB 3.0) and DPS (Dead Pixel Suppression) technology, dead pixels (including both hot pixels and cold pixels) of the image are swept away. It starts working the minute you turn it on!
Currently they have the IMX178 color and mono, the IMX290 Mono and the IMX462 Color cameras. They named all their cameras from Mercury up to Neptune, but they only have the Mars and Neptune cameras available. On sale now at most retailers online. Currently the Mars Color IMX462 is $269 and the Neptune IMX178 is $319 and the Mars Mono is $329.
They also include an adjustable tilt plate, for the annoying Newton lines you find in Solar imaging.
I plan on purchasing at least the IMX462 and trying it out for fun.
