    Sadly not.

    Just noticed you are in Georgia. I was in Savannah a couple of weeks ago. What a stunningly beautiful place.

    I'm just up the road in Macon. Savannah is gorgeous; I love River Street and Tybee Island. Did you see the ocean?

  2. Imaging and observing on the night of opposition revealed the notable Seeliger effect. The rings of Saturn show significant brightening from the full illumination of the Sun. I included an image from just a week prior "highlighting" the effect. Both images were captured with the ASI 224mc and Orion 180mm Mak-Cass using FireCapture, processed in Registax 6, with post-processing in Photoshop. Identical capture settings were used for both images:

    I generally prefer imaging Saturn in the weeks before or after opposition. The Seeliger effect seems to wash out the finer details (at least for me).

    Images captured at r.j.s. observatory™

  3. I had a great Friday night with my Big Mak (Orion 180mm Mak-Cass) and I stayed out late enough for Saturn to get good elevation. I did some lucky imaging with the trusty old ASI 224mc and produced the following image:

    You can see the more edge-on appearance as compared to this image from 2021:

    Saturn is moving toward an edge-on apparition in 2025. Will be most interesting!

    Clear skies!

    Thought I would post these images of Saturn with IR added in the mix. I know it's not every ones cup of tea. I personally dont think it as brought anything new to the table as the Asi290 is already sensitive in IR.

    The IR seems to add a certain glow to the images and an almost three-dimensional quality. I love them!
