Tonight I put up the N 150/750 scope, with the almost-for-free extension tube to get meaningful sizes for the projection of the planets. Because the ADC I order from the internet still has not arrived, the dispersion is severe. However, there is a trick: to get the most out of the Cassini division, I used only the red channel as luminance, so lots of editing went into each Saturn-picture. The seeing was surprisingly good at first glance, but the stack quality revealed it was more of wishful thinking. Camera: ASI 224 MC, mount: HEQ5. The grey 1.25″ extension tube is from the nearest hardware store.
