    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:

    Very nice Reggie. Have you tried Neptune as well?
    Visually both are fun targets

    I think you succeeded in a grand manner. I know from experience it is challenging. Congratulations on your Uranus image.

    Thanks, Gabby. I've taken pictures of Neptune when it was in conjunction with other planets using prime focus imaging; I haven't tried this method yet. My biggest limitation will be having enough aperture to get some good data. I'll give it a go though!

    Thanks, Ed. I've seen images using larger aperture scopes that show evidence of the polar hood. I'm happy to get the disc at all (and some hue) lol!

    I'm using the ZWO ASI 224 MC camera with the Orion 180mm Mak. I also used a Celestron 2x Barlow for this image to get some size. I use the same setup for most of my planetary images.

    Reggie, I wish I could see your original image on a larger screen. The one you posted appears to show detail, including some lightening in the North polar region at 5 o'clock. Years ago the sky where I live was much better and allowed me to do this observation of Uranus:

    I see a lot of similarity in my 2014 sketch to your image, including the lightening at the North polar region . Reading my comments in the sketch I included a comment about the extremely bad light pollution. Wow, back then I had no idea just how bad the LP would get.

    Thanks for posting your notes, Ed. I'm going to look at my image more closely. I wasn't expecting to get any detail with 180mm aperture. Could it be I was able to capture some evidence of the polar hood??:eek::eek:

    I believe you definitely did capture evidence of a polar hood, as well as a light equatorial band. :)

    I DID???? Wow, I need to take a closer look! Thanks for pointing that out, Ed ;) I guess 180mm can gather enough light to capture that.

    I looked closer and I could see both evidence of the hood and a subtle striation! This is exciting! :D

    I'm so happy for you that you took that great image. I'm excited, too!
