@janvenetor @anulahtinen @jpakkane Käsittämätöntä, että sellaista tarjotaan pokkana tuotteena. Edes Google Translate ei tekisi sellaisia kökköjä.

@sinituulia The picture from the astronomy book of my father, and of my childhood.

@AnnFinkbeiner@sciencemastodon.com @jab01701mid@mastodon.social This was one of the first things I learned, from my father's astronomy book when I was still in primary school. The last figure in this chapter. Wonderful book! https://www.gutenberg.org/files/59744/59744-h/59744-h.htm?page%20=55#chapter08

@sinituulia Venus is such a rewarding object, even in a small telescope, or even in binoculars, provided they are on a tripod. Around 'brightest shine', close to eastern or western elongation, she shows as a Moon-like crescent, just like Galileo described her - a spherical world orbiting the Sun, dark but illuminated by the Sun. It never gets old.

@sinituulia In the general neighbourhood of the Sun, i.e., morning or evening twilight, that is likely. Especially if the sky is so bright that you cannot see any fixed stars.

In this case (I checked) Venus was in her orbit almost behind the Sun and not very bright. In a telescope she would look almost full but small, because of the distance.

In the weeks following this, she vanished behind the Sun and then re-appeared as the 'evening star'.

@sinituulia Morning 7 o'clock of that day, in Stellarium. Location Tenala. Yes, Venus

@sinituulia Wow, you captured the Earthshine eli maatamoa!

The planet is probably Venus. Not sure without the precise date.
