I set up my new short tube refractor, an Explore Scientific AR102, for some views of the nearly full Moon and Saturn. Visually Saturn looked sharp and steady and I was able to share the view with my grandson Casey. I saved imaging Saturn for the Questar with it's longer focal length. The moon showed some color aberration around the edge of the lunar disk. I took some prime focus images of the moon, they needed some color correction at the edge, but I was pleased with the sharpness of the image below:
Nearly full moon from Austin 2016-07-18 04:16 UT. Explore Scientific AR-102 with Sony a6300 at prime focus. Best 8 images 1/200 sec at ISO 100. Stacked and deconvolved in Lynkeos. Final crop, exposure adjustment and disk edge color correction in Photoshop.
I also set up the Questar for images of both the Moon and Saturn. I was struck by how much easier the Questar is to setup for grab and go astrophotography than the refractor on an equatorial mount.
