Saturn’s family, 2019-05-09

I dug out Saturn’s moons, from a longer expo series of images, and composited it with the lucky imaged Saturn. Below’s the process. There is also a random star photobombing the frame.

Saturn nostalgy 2014-06-27 reprocessed

I reprocessed an old image of mine, from 2014, recorded with a Scopium webcam, N150/750 on a motorized EQ3 mount.

Saturn 2019-05-09, from 500k frames

I decided to do something desperate given the low altitude of the ringed planet. To make the seeing worse, I also happen to have a huge part of the city right under the southern sky, from my vantage point. One more thing, the rather unusually cold weather made many people to fire up their heating, which runs on natural gas and means many little chimneys contributing to an even worse seeing. So I decided to combine 500k frames recorded over the course of an hour or so and select the best 2k frames. The raw material that entered PIPP combined mode was 36 GB of SER files with the ROI of the ASI camera set to 240×160 pixels. Then came a very long processing, taking segments of the image from different parts and stages of the process – so bordering on painting the image based on the real images.

So the gear used: ASI 224MC, TS Optics ADC, Barlow, N 250/1200, HEQ5 with a motorized focuser I hacked together. Location: Kolozsvár, Romania.

Software: SharpCap, PIPP (planet), AS!2 (surface), Registax and a photo editor.

Saturn – 2017-06-04, reprocessed 2019-04-30

I reprocessed an image of Saturn, recorded in 2017. Looks like Saturn too was made with the N150/750, but for certain, my only color camera was the Scopium webcam, a rather modest piece.

Saturn 2019-04-25

I imaged Saturn with the ASI 224MC, TS Optics ADC, Barlow, N 250/1200, HEQ5 setup. 60k frames went into the planet (it doesn’t really get motion blur like Jupiter) and a few frames of 200ms into the satellites. Enceladus was at (or below) the noise limit, however, I added it onto the final picture. Below some more pictures with at around 10k frames each.

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.

Some Saturn images

Saturn

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.).
