Saturn – 2018-09-02

Saturn, 2018-09-02

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.

Using the HEQ5+MC102/1300+ASI224MC setup, I’ve been recording Saturn. Some stack contain the best 5% of 10k frames. And I present a compositing process, showing Tethys, Dione, Rhea, Enceladus and maybe Mimas.

Jól kalibrált monitoron mindegyik számnál elkülönülő árnyalat látszik. Ha mégsem látszanak, akkor a megjelenített képek színhiányosan rajzolódnak ki. A monitort valószínűleg kalibrálni kell.

You should see distinct shades for each number. If those shades are not clearly visible, the displayed pictures will lack accuracy. Your display most likely needs to be calibrated (brightness, gamma, contrast etc.).
