Moon-Mars Conjunction – 2018-07-01
Moon, Mars
Old habits die hard, so I pointed a raspberry pi (an old friend of mine, a model B+ from a few years back, still functioning like a charm) plus some compatible camera with a large field of view (fish eye like) to record. Record what? IDK, just make timelapses and something *will* come out of it.
So I captured the conjunction of the Moon and Mars with a very modest and toy-like MacGyverish, but at the same time very versatile setup. The Raspberry Pi board is „floating” in a drainage tube with tight fittings, with a camera front from a cheap mock camera for weather protection and an ND filter in front (the Sun has a tendency to burn its trail into the sensor, already visible on every image). Since I risked to move the camera, the ND filter stays on for the night which kinda sucks… I know.
I also created a max combination of all the recorded images, function finalPixel(x,y) = max(pixel(frame[0], x,y), pixel(frame[1], x, y) … pixel(frame[n], x, y)) where max compared values of luminance = (rgb24 >> 16) + ((rgb24 >> 8) % 256)*2 + (rgb24 % 256).
Jupiter Rotating – 2014.11.03. Dawn
Jupiter, Europa and Io
I filmed the giant Jupiter a whole night as its Great Red Spot entered and left view. I also filmed Io exiting from behind Jupiter then move away and Europa moving towards the planet. And put all data together to show it as a time lapse movie.
Setup and metadata
I used my known setup: the 150/750 newton scope on the motorized EQ3 mount, a 2x barlow + extension tube (another barlow tube with the lens removed) + Scopium webcam (640×480, 8 bits RGB). I disassambled and adjusted the barlow+extensino tube+webcam assembly two times during the night to get the most out of the setup in terms of a great disk photo, knowing when putting all the frames together compensating for the rotation, xy offset and size will be only a small fraction of my problems.
To be noted that the observation started with Jupiter relatively low, near the horizon (about 30 degrees, in a city) and that the seeing varied substantially during the session, peaking at an almost perfect seeing, one I’ve never seen before from within this city.
I took the first video on November 3rd, 2014 at 0:53 UTC and the last one at 4:36 UTC. Location: Kolozsvár city, Romania, EU.

A Jupiter körül
Bő három órányi felvételből gyúrtam az alábbi videót. Van benne szinte minden, amit a Jupiter esetében el lehet képzelni: a bolygó tengelyforgása, a holdak mozgása, napfogyatkozás a korongon, ahová a holdak árnyéka esik, az Ió tranzitjának vége, a holdak pályája és kirajzolódó pályájuk hosszának különbségében végülis a 4:2:1-es rezonancia.
A Jupiter és holdjai
A hatalmas mennyiségű adat mellett a videószerkesztő programok bugjaival és meg kellett küzdenem.
Csillagtúra a tévében
A Román Tévé Kolozsvári Stúdiójában az Erdélyi Figyelő műsor vendége volt a Csillagtúra. Spitzer Jutka kérdezett.
PS: nagyon ciki, hogy reklám van/lehet a videóba fűzve (alul a sárga szakasz az időcsíkon), bocs, ilyen a jutub.
