Jupiter, Callisto 2019-07-14

Bad seeing and passing clouds. Actually, after some blessed days, this is more like the normal. ASI 224MC, TSO ADC, N250/1200, HEQ5. Balcony, soapbox.

Jupiter 2019-07-13 rotation

The seeing was bad, so I just combined the frames. Nothing fancy. ASI 224MC, TSO ADC, N250/1200, HEQ5 with the soapbox project.

Shadows on the Moon 2019-07-12-13

This is a not mobile friendly post with a 4MB gif, don’t just open it. The central shadow is getting shorter as the Moon becomes more and more full. The exact datetime of the frame to the right is 2019-07-12-1848Z, I messed up the filenames a bit, sorry.

Saturn, 2019-07-10-11

Half an hour of raw video (>100k frames, tens of gigabytes) went into this picture of Saturn. The low altitude craves for the huge number of frames to … well, have enough luck for the lucky imaging. At 178°42′ elongation, this is just one day away from the opposition. The rings are surprisingly bright. ASI 224MC, TSO ADC, N250/1200, HEQ5 guided by the soapbox on my balcony.

Jupiter, Ganymede 2019-07-10

As usual, this is from the balcony observatory, ASI 224MC, TSO ADC, N250/1200, HEQ5. Planet tracking is done by the soapbox project. The seeing had good moments, but the low altitude of the planet and the fact that I have one of Romania’s largest cities underneath is certainly not helping, these beyond the generally shitty astroclimate of the Carpathian Basin. After the many nights I was up at 4AM to capture the planet, it has well passed the opposition by now and its going away from the horizon of my vantage point. It was an interesting collaboration: me sleep-deprived while getting some good views and Jupiter… doing what it’s been doing for billions of years now.

37 individual videos have been recorded and processed for the animation below, from 2019-07-10T18-54Z to 2019-07-10T21-50Z, each video about 3 gigabytes, equal lenght of 90 seconds, and equal gaps between.

Jupiter’s weather – a quick look

Only five days apart, the planet has shown some interesting changes. More images are coming. From the balcony, ASI 224MC, TSO ADC, N250/1200, HEQ5.

Home Observatory 2019

The balcony, as a temporary(?) home observatory

I am a lazy man, so I automate, leave in place, pre-program — and stuff like that. For Jupiter and Saturn, I made my rather humble balcony into a humble observatory, before the real estate developers (this is a politically correct name for what they really are) fuck up my horizon.

Since accurate polar alignment is not feasible when one can just accidentally kick the mount, just that tiny little bit, and I don’t intend to do deep sky from here, the whole thing is aligned by smell and then guided by the soapbox.

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.).
