Binoculars with a formula of 10×50 are among the most popular.Such binoculars are suitable for both terrestrial and astronomical observations.In my opinion, 10x is the limit for comfortable observation without using a tripod.The Pentar company kindly provided me with an interesting Pentax SP 10×50 WP binoculars for testing.The binoculars are quite new, the announcement took place in January 2015.

The rise of Saturn comes all earlier – now I started shooting it around midnight. Visibility conditions on the planet are improving. Less than a month is left before the confrontation – it will come on July 10, 2019.
In this post I will share my impressions of the daytime shooting of Mercury.I’ll say right away that this shooting turned out to be difficult for me – the scorching Sun, the planet constantly knocking out of sight of the eyepiece, about 20 alignments of the mount for the Sun, a long peering into the bright blue background of the sky really tired me.However, I still managed to catch Mercury and confidently fix its phase.I think that with a quieter atmosphere, some details of the planet’s surface can be captured.
