Saturn 2019-09-22

This was an exceptional night with good seeing, rivaling only a night I had in August. About 300k frames went into this Saturn, with the usual setup HEQ5, N250/1200, TSO ADC, ASI 224MC (cooled), home observatory, mountpusher. In the meanwhile I finished a clone of my mountpushing soapbox, with the exact same components, the exact same soapbox, I only made it a circuit board instead of the cable spaghetti the first one has become after adding and adding functionality, like the buzzer and the RJ45 socket for the focuser. But the soapbox is another story. Overexposing the final stack, to my surprise, reveals some of the fainter moons of Saturn, near the planet – I removed the uneven background from the final picture.

Io, Jupiter, Europa 2019-09-22

It wasn’t a surprise that I caught Jupiter, for I was cooling the telescope for quite a while before sunset, but it was a nice surprise to see Europa’s shadow departing — reminding me of the good old times of this year’s  Jupiter season when the planet was visible for several hours (though still as low as it can get, above the city’s turbulent air). HEQ5, N250/1200, TSO ADC, ASI 224MC (cooled), home observatory, mountpusher Photo taken at 19:21 local time with the Sun just behind the hills to the west of the city.

Jupiter and Io – 2019-09-21

Jupiter and Io

From the balcony observatory, the Jupiter season, which was shitty even at its best, is ending. It’s less the horizon’s problem, for Jupiter hides behind a building, but more the altitude’s. The usual gear HEQ5, N250/1200, TSO ADC, ASI 224MC (cooled), home observatory, mountpusher

Saturn 2019-09-21

Using the usual gear HEQ5, N250/1200, TSO ADC, ASI 224MC (cooled), home observatory, mountpusher I recorded 300k frames of which the best got into the picture below. Seeing conditions were outright bad with some clearish moments, same as the last few days. It’s a boiling soup up there.

Jupiter and Io – 2019-09-14

Jupiter and Io

From this year’s standard gear,  HEQ5, N250/1200, TSO ADC, ASI 224MC (cooled), home observatory, mountpusher I observed Jupiter and Io on the evening sky. The Jupiter season is mostly over, as is the Saturn season, but one may still capture some nice shots.

Szaturnusz 2019-09-12

I imaged Saturn from my balcony.  HEQ5, N250/1200, TSO ADC, ASI 224MC (cooled), home observatory, mountpusher, 200k frames, decent but not good seeing

Jupiter, Io – 2019-09-01

The early evening, still blue sky has its own charm, when it lets through the planets. The Jupiter season is kinda over, but it’s still possible to capture good frames. On the second one, the blue sky is subtracted and the gamma is adjusted to compensate for the lost brightness. 20:01 local time, HEQ5, N250/1200, TSO ADC, ASI 224MC (cooled), home observatory, mountpusher

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.).
