My current amateur astronomy equipment is limited to a Nikon D810 digital SLR camera, a 70-200 f/2.8 lens and a tripod, plus a couple of binoculars. The camera can do ISO 12800, which in combination with f/2.8 is adaquate for reasonable trail-less night sky photography. The camera uses software enhancement to fake a maximum ISO speed of 51200, but the resulting image is too grainy and full of processing artifacts. I would like to get a 200-500f/5.6 lens, but that would only work for the moon, and is too slow, requiring to much exposure time, for deep sky objects since I have to tracking mounts.
Pentax just released a camera which has built in GPS, and a sensor shift capability which Pentax used to allow the camera to track stars internally during long exposures by moving the sensor. The camera also has much higher stated ISO capability. I am looking forward to testing that camera.
