Uranus - IR with moons - Oct 26
We had some reasonable seeing here last night, it was the first time for about six months that I have seen an Airy disc..so it was an opportunity to continue the quest for a decent Uranus image.
The 90% moon close by made pointing a bit more difficult, but didn't affect the video. With the C11, TV2.5x Powermate, and DMK21AU04.AS camera, I managed 2700 frames of IR at 0.5s exposure (34 mins) and 5400 of RGB at 0.125s. For R, I used a deep red #25 wratten instead of the usual R. For the moons, I took 20 frames of L at 5.7s exposures.
Stacked with AS!2, layers composited with Gimp, and here is the result. The moons are, from top to bottom, Titania, Umbriel, and Ariel.
