Uranus

The seventh planet from the Sun is Uranus, one of the blue planets in our solar system. My first attempt to image it was on 13 October 2020, the day that Mars reached opposition that year.

Imaging was done using the Celestron C11 XLT EdgeHD, a 2" TeleVue 2x PowerMate, ZWO ADC, and ZWO ASI290MC camera. The gain was raised to 435 to keep the exposure at a reasonable 35ms. A movie of 200 seconds was recorded, 35% percent of which was stacked using AutoStakkert3 using 1.5x drizzle. In PSP the illumination was increased, while a 2.5 pixel Gaussian filter reduced the noise. Finally the saturation was raised and a non-linear stretch was applied to make the planet stand out a bit more.
