Mars up close

The dust on Mars is starting to clear. This is a first light image with a new camera on the Questar, a ZWO ASI224MC one shot color planetary video camera. I'm loving it! One stop more dynamic range and twice the frame rate pulling down 16 bit color images that I was getting before with 8 bit images. Mars is very close to it's maximum size for this opposition 24.3 arc sec in diameter. It won't get any closer, but I'm hoping for clearer skies on Mars in the weeks ahead. This was also my first time using FireCapture under macOS - very, very sweet. This image is L/R reversed.

Image take 2018-08-02 05:09 UT, fair seeing, with a Questar 1350/80mm telescope, 2x Dakin Barlow, and ZWO ASI224MC planetary video camera. Best 5% of 5750 images from FireCapture, stacked with a 3x drizzle in AutoStakkert 3, deconvolved in Lynkeos, with final exposure and crop in Photoshop
