  1. It was quite a challenge, but I was up for it, and with a clear night calling I couldn't resist! Same setup: 180mm Mak, ASI 224mc, Celestron 2x Barlow, Firecapture, Registax 6, and Photoshop. The most difficult part was getting such a dim target (especially using Barlow) onto the sensor:

    For comparison, here again is my recent image of Uranus using the same setup:

    Cheers!

    Nice capture Reggie. My only advice is to denoise more or go easier on the wavelets as you seem to have some noise specs; with your aperture and colour capture, you will not have any details.

    Thanks, Kostas. I'll probably play around some more with the data. I knew I wasn't going to get detail but it was fun getting some shape and color :)

  3. I never tried very hard to image Uranus except when it was in conjunction with a much brighter planet using my DSLR. This particular night I decided to try my luck with the ASI 224mc/Orion 180mm Mak combo. Getting the tiny disc of light on the sensor (and with a Barlow, no less) was a bit of a challenge but doable. I wasn't expecting to get any detail but hopefully a well-resolved bluish-green disc. I think I succeeded:

  4. I only planned to have a long evening of observing when I noticed the GRS was nearly dead-center. Of course, I had to gather some quick data after which I resumed an extended observing session (from about 8 p.m. to 3 a.m. - no work the next morning)!

    Nicely done Reggie.

    It must be an illusion with a bright spot in the SEB to the left of Io's shadow, making it look like Io following the shadow as it was prior to opposition.

    Thanks, Geof. It actually was Io; left-right orientation was flipped.
