There is nothing special about this date, no eclipse was visible from most of Romania, I simply imaged the Moon. I used the MC 102/1300 plus the Canon 1100D mod for the disk (13 frames) and the Scopium webcam for the details. Enjoy.

You may already know my astronomy catalog search engine, the DSO. It includes all the catalogs we amateurs use: the Messier, Caldwell, NGC, IC, Arp, SH2, Collinder, Melotte, Abell planetaries, it even grabs the list of exoplanets from a wiki page to always be up to date. But this is not all. It includes some ugly formulae to know about the position of the Sun and the Moon, and do some math based on  the geolocation of the user. The DSO however is more like a text mode tool, or an API. It is good to just look up what Messier 51 or NGC 7000 is. Anything more complex requires some heavy wizardry even I don’t master and need to look up in the help I fortunately did write.

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.).
