I've been putting the new Optolong IR685 pass filter through its paces to assess how useful it may be in planetary imaging. After some encouraging results on Mercury earlier in the evening (see previous post) I thought I'd have a go at something further out.

Uranus is said to come up ok with IR pass filters so seemed an obvious selection, especially since my previous efforts were not very good with OSC. Using the IR685 and my asi290mm (mini guide cam) here really neatened things up and I'm quite pleased with the improvement

I processed as normal in Registax and then did another version used the gamma planel to reveal the moons (thanks for the tip Andrew [Tulloch]). Another vid was done using the ASI294mc to get some colour, and I combined all of these in layers in GIMP for a final result. Should note that the rgb version was extremely poor again compared with the IR and really only useful for colour.

Thanks for looking!

EDIT- thanks to Dennis for his input it appears that I have captured a small magnitude 14.5 star photobombing the 4 moons. Guess I could have erased it pretty quick but left it there anyway for completeness. Miranda remains elusive so close to the planet.
