SATURN 2025
This year, Saturn will have a peak altitude of around 80deg here in Cebu. These images were taken using a Celestron C14 mounted on an Astrophysics AP900GTO mount and a QHY5III585M and the QHY5III585C camera. RGB is done using a set of Chroma Technology RGB filters on a Starlight Xpress Motorized filter wheel. Methane band images are done using a Chroma Methane Band filter (889nm 18nm bandpass). Amplification is done using an Astrophysics Convertible Barlow working at 2.5X. I use an Prima Luce ESATTO 2 focuser. Image acquisition was done using Torsten Edelmann's Firecapture 2.7 software. All images are NORTH UP! Processing was done using AutoStakkert! and Registax. For info on Saturn's belts and zones please click this link. You can also see my past images of Saturn at the ALPO Japan Kansai Branch site.

April 26, 2025 I did not expect to image today because it rained hard all night last night. But somehow there was a clearing on the eastern horizon. Seeing was still very unstable with Saturn at 24deg. Saturn is still "ringless". Even in methane band, no ring can be seen despite the ring being many times brighter in methane band that the surface of Saturn. Rhea is prominent on the methane band image as a bright spot. The south polar cap is very dark.

April 14, 2025 I took an early image of Saturn today. Saturn was only 14 deg above the horizon and seeing was horrible especially with the rising sun and twilight. It is a bit weird seeing Saturn without any rings! Because of it's current orientation, we can only see the shadow of the rings. | ![]() |
