While the camera still had no problem getting #Venus and #Saturn clearly this evening with the Sun 10° below the #Bochum horizon, the latter was not evident to the naked eye anymore (as it had been yesterday) at any solar depression - game over? Also the full moon rising, sadly long uneclipsed again. More pictures from this evening in facebook.com/dan.fischer.393/p

Moon rising and #Venus und #Saturn setting from #Bochum, Germany, today: the 2nd image coincided with 1.0-mag.-Saturn just having become visible to the naked eye, at an elevation of 6 3/4° with a solar depression of 9 3/4°. More pictures in the album facebook.com/media/set/?vanity from image 45.

A Roman agate cameo depicting Venus Victrix, circa 1st century CE. Venus is shown from behind, a helmet in hand, and a himation draped just below her ample bum. Beside her a round shield rests on the ground and a column serves as an arm rest.

Four timesteps from the final 7 seconds before #Venus vanished behind a distant roof structure today: each image 1/3.2 second at f/2.8 and ISO 400 with maximum digital zoom yielding an equivalent focal length of abou 3 meters, pictures in full resolution and cropped, no further processing. The spectral #dispersion is clearly visible; unfortunately Venus 'hit' the structure from the side, so cutting off the red and leaving only the green/blue upper part as in #AtmosphericalOptics

Yay, in spite of #Mercury having dropped to 1.25 mag. and more clouds than yesterday here it is again, together with low #Venus, 1/2 hour ago this evening from #Bochum, Germany: two images 3 minutes apart, with solar depressions of 8°40' and 9°10', resp., Mercury at 5.3 and 4.8 and Venus at 1.3 and 0.9 degrees elevation, both 1/4 second at f/2.8 and ISO 800. Saturn was also detected again, much higher and way out of the frame.

No, there is no magnificent 'planetary parade' in the evening right now as the internet shouts from everywhere but on the other hand there is also more to see than just Jupiter high in the sky - as I could confirm Wednesday from Bochum, Germany, at 51.5°N, #Venus is already a bright if rather low evening star while #Saturn and #Mercury could still be spotted above her: see facebook.com/dan.fischer.393/p for more pictures and hard numbers!
