Friday night I went up to the River Ridge Observatory to shoot some planets. I started with Venus which is about as high in the sky after sunset as it will get in this apparition. It was disappointing so I moved on. Next up was Jupiter. I’m using a monochrome camera with RGB filters so here we have the combined result with the red, green and blue images that went into it. The color image is softer than I’d like but shows Io and it’s shadow that were transiting the disk of Jupiter this evening, They were both near the meridian of Jupiter when I started and visible on the laptop. Below are the red, green, and blue filter monochrome images that went into the image above. Notice the red spot is barely visible in the first image which is the red channel and darkest in the last image which is the blue channel.
