When adjusting the focus I used this star as reference. I liked its color. Very impressive.

Single frame, ISO 1600 , 15 seconds.

Also known as Avior. Binary system, with separation of 0.46 arcseconds and only 2.0 difference in magnitude. Epsilon A has 2.2 and Epsilon B has 4.1 . They form an eclipsing binary system with a period of 785 days.

The main star with temperature of 4100 K,  mass about 4.6 times,  diameter about 20 times and  luminosity about 110 times that of the Sun.

Its companion much hotter with  temperature of 23,000 K. Diameter of 6 times,  mass of 16 times and a luminosity of 8800 times that of the Sun.

My set of equipment has about 0.65 arcseconds of resolution, therefore ... no chance of register both stars !

Nice images, don't often see stellar images. Usually it's M31 or M42!
