I made a new blog post, and in it I show how I build a device to monitor the voltage of a 12V battery and share it over the Internet. Something that might be useful for remote astrophotography rigs or when building off-grid power installations. I'm using a Raspberry Pi Pico and some basic circuitry to make it all work. Take a look! https://stfn.pl/blog/22-pico-battery-level/ #RaspberryPi #RaspberryPiPico #offgrid #blog #soldering #astrophotography

Many newcomers due to what's happening in The Bad Place, so here's another #introduction. Hi! I'm an astronomer and science communicator at the European Southern Observatory. Below is a pic from my previous "office" at ESO's Paranal Observatory in #Chile. I now work full time as Media Officer at ESO's HQ in #Germany. I mostly post about #astronomy #space #photography and #astrophotography

I spent the afternoon stacking our images of the North America Nebula's Cygnus Wall (NGC 7000) from the past two nights. These photographs are unstretched (the second image was viewed using SIRIL's histogram function), but they highlight the limitations of our equipment and the challenges of NYC's light pollution levels. Final edited images are forthcoming! @[email protected] #Astrodon #astrophotography #nebula #ngc7000 #SIRILIC

NGC 2264 - Christmas Tree Cluster + Cone Nebula Ein Sternentstehungsgebiet mit offenem Sternhaufen und einem großen H-Alpha-Gebiet (Hα = angeregter Wasserstoff). Der rechts im Bild zu sehende Konusnebel ist eine Dunkelwolke (idR Staub), die von den heißen Sternen angeleuchtet wird und deshalb so sichtbar ist.

Planetarium software simulated sky view for Friday, 2 June. The planet Mars will be in the Beehive cluster (Messier 44) in the constellation Cancer. Good opportunity to look at this piece of sky with binoculars or small telescope, or take a photo. (It's full moon, so the sky will not be very dark.) June 1 has Mars on the west edge of the cluster. Look to the west as it gets dark after sunset. Orange colored Mars is not bright, but it's left and above Venus, which is brilliant now. #Astronomy #Mars #Venus #Astrophotography #Astrodon
