Mars, Saturn and Antares

At the end of the night before dawn (on 27 of  March) I captured three bright celestial bodies: two planets (red Mars on the upper-right, Saturn on the left) and Antares (the brightest star in the Scorpius; in the picture it is in the bottom corner of the triangle). The name Antares is derived from the Ancient Greek word which means "equal to-Ares" = "equal to-Mars". It is called so because of its reddish color (like Mars).

The picture was shooted while unsuccessful hunting of the comet 252P/LINEAR. I found out later that the comet is quite diffuse so it is hardly to register especially when sky is partially covered by clouds.

Jovian System

Picture was taken on 2016-03-15 at ~21:02(UT+2)
Kyiv (Osokorky)
Canon EOS 600D + 55-250mm EF-S f/4-5.6 IS II on a fixed tripod.

A movie was captured, 800 frames from it were processed with PIPP, 70% of them was processed in Autostakkert2, then in Registax6. The final image is a combination of two pictures, processed separately to highlight planet (1-st pic) and its satellites (2-nd one). Then the two pictures were combined in Gimp.
Movie parameters: F = 250mm; ISO = 200; f/7.1; each frame exposure = 1/30s; frame rate: 25.
