Jupiter April 13, 2016
Jupiter has been prominent in the southwestern sky for months and I've been using it to align my telescope without ever taking much of a close look at it. As part of my ongoing field test of the Questar PowerGuide 3 mount, I decided to take one good run at imaging a GRS transit. The 3.5" Questar does paticularly well for visual observation of the sun, moon, and planets, and with a bit of coaxing can deliver a respectable image as shown above.
Tech Stuff: Questar 3.5" telescope on unguided PG3 mount; imaged with ZWO ASI 120MC camera through 2.0X Televue Barlow. I'm a bit rusty with planetary image processing so I cycled through Registax 6.0 and Autostakkert 2 plus PIPP and PixInsight. Final image used sharpened stacks from 6 sets of 1000 frame avi files collected during the 20 central minutes of the GRS transit, derotated with WinJupos and finished with PixInsight, GIMP, and ACDSee.. Imaged from my yard 10 miles north of New York City.
