Mars, Jupiter, Saturn and Uranus relative sizes on September 28

On September 28th I photographed Mars, Jupiter, Saturn and Uranus.

The below image is a combination the photos of the four planets and shows their relative sizes in the sky.

All photos were taken with a SkyWatcher 1200/250 telescope, with an eyepiece of 10 mm focal length projecting on an ASI120MM camera. The RGB filters between the eyepiece and the camera.

2,000 photos were taken for each of the R/G/B channels. As a reference, the speed was 94 FPS (frames per second) for Mars, 61 FPS for Jupiter.

Software used: FireCapture, AutoStakkert, PixInsight, RegiStax and Photoshop.

Did not need to use WinJupos to de-rotate because each channel was just around 20 to 30 seconds, i.e., max 1.5 minutes per image.
