At long last I have managed to image Caliban, also known as Uranus XVI. It is a small (circa 72km) outer satellite of Uranus which was discovered in September 1997 using the Hale 5m telescope at Palomar. Incidentally, Sycorax (U-XVII)was discovered in the same observing session. That satellite is around 1.7 magnitude brighter and so much easier to observe.
Although a three hours exposure, unfiltered for maximum sensitivity, was used the signal to noise ratio is barely 3 and serious image processing was needed to produce a relatively clear image. Even so, it is not especially obvious. The reason is that the MPOC ephemeris predicts that the satellite has a magnitude of 22.2 at the time of observation.

This is my third Uranus capture this season. I am much happier with this result.
The seeing helped a lot and the sky quality was favorable.
This image is the result of 5 de-rotated videos on Winjupos, all captured with IR742 filter. The result was used as luminance in the composition. RGB came from a normal color capture.
Following the images of other friends, we can notice the atmospheric activity on the planet. It seems to be changing every week. Many changes can still happen until the opposition.
Hello stargazers, welcome. I had posted a picture yesterday of Uranus that had appeared to show its rings. I am using a Nexstar 4se, a 2x Barlow, and my Neximage Burst Color and capturing hundreds of photos and stacking them for my results. But still had me and others curious to if I were actually seeing the rings of Uranus or maybe just a glare of some sort.
So I got back out there this morning, might I note I live in FL where the weather tends to stay hot so clear imaging during this time of year can be difficult, but not impossible as this image that I stacked 150 out of 300 images taken may show that statement holds true..............or I could just be mistaken the object in the image, but all in all I am feeling pretty confident that I have a decently clear image(stacked 150 images) of Uranus, its rings, and one of it's distant moons. It may be necessary to zoom in on my photo in order to see the moon it should be down and to the right of the planet a good distance in relation to the size of planet, I noticed that looking at Uranus in the photo helped bring the moon out just like stargazing in real-time.
If anyone can better distinguish what I might have done right or wrong here any help would be appreciated (also forgot to change format save for my images so I am stuck with .bmp and setting it as a download, sorry for any inconvenience.) - - - J47(JAY)
Hi my name is Jay, new to all and any forums, lol. Not sure where to start so here I go. I have a few questions about Sirius the double star while observing through my Nexstar 4se telescope using a 2x Barlow and my neximage burst color. While I was able to capture quite stunning results of the star Sirius, this morning before sunrise, I was curious though as to if I might have incorrectly focused my scope on the star or if this image is a clear image of the star? I will attach a brief 7-8 second video I took this morning. It was the first time I had gotten to focus my scope on the star as it kept drifting before but I solved the drifting issue as a result of improper anti-backlash. But now back to the video, was wondering if any of you could help determine if I properly focused on the star because from what I see the star appears to be in the shape of an out-of-control atom in the video and at the center it is black, is this the observing of a quasar? Thanks for all the help in advance if anyone stops by thanks for the time and efforts here's the video.
