This is the first sequence of test images from a new project to see if I can take at least basic images of some of the satellites of the outer planets using my Seestar S50. I chose Uranus as the first test subject as the planet itself isn’t too bright and the orbits of its principal moons are facing in our general direction so you can see them moving in a nearly circular path around the planet. The images below summarize my observations on 6 consecutive evenings from 11/12/2025 through 11/17/2025. The specific dates and times (EST) include (from center to upper right) 11/12 (20h29m), 11/13 (20h29m), 11/14 (20h55m), 11/15 (22h46m) 11/16 (21h00m), and 11/17 (21h29m). Each source image was a 30x10sec field centered on Uranus taken using the Seestar’s Stargazing mode. These were aligned and combined in Photoshop.
The first composite image shows the field aligned on the stars showing the apparent motion of Uranus against the background stars. If you look closely you can see two moons that travel along with Uranus and shift their positions around the planet each night. The closer of the two is Titania (Mv 13.7) and the outer is Oberon (Mv 13.9). I initially thought that I also caught Umbriel (Mv 14.6) but it is likely hiding just within the glare of the planet. The second composite image shows the field aligned on the planet showing the motion of the two satellites around the planet.
Neat stuff.
