A simple farewell tribute.



Sorry for the digression, but to whom I'll tell this.
My place to do astronomy, my "observatory" always called "The Eye of Owi"
And this is so in recognition of my cat, Owi, loving and loyal companion of countless nights of astronomy.
Well, after 16 years from Owi decided to go to the place we've seen so many nights together.
Well this little farewell to my dear and unselfish friend.

3 small galaxies in one photo


All three are in the constellation Virgo.
NGC 4760 is the brightest and spherical. It is an elliptical galaxy.
Its coordinates are RA 12h53m06s, -10 ° 30'00 ".
Its magnitude is 11.40 and its size is 2 'x 1.8'.



NGC 4766 is a galaxy of type SO. It is the closest to NGC 4766.
Its coordinates are RA 12h53m06s, DE-10 ° 22'59 ".
Its magnitude is 15.00 and its size is 1 "x 18"

.

The other is NGC 4575.
Its coordinates are RA 12h 52m 48s, -10 ° 19'00 ".
Its magnitude is 15.00 and its size is 1.2 "x 18".
The 3 are spaced 0.1 to 0.2 °.



Another galaxy in the constellation Virgo



At this time, since these latitudes, the constellation Virgo is high at midnight.
Then take the opportunity to photograph these wonders located millions of light years away.
This photograph is of the galaxy NGC 4781. It is a smaller galaxy that the Milky Way. Has light 55,000 years in diameter.
Its coordinates are RA 12h54m24s and -10 ° 31'59 ".
It has a magnitude of 11.10. It is much more tenuous than Messier 104.
Are in Group II of Virgo. Its size is 3.4 "x 1.4".
It is a barred spiral galaxy SO class.
Within its structure is a way to hook very peculiar.
He catches sight of a smaller galaxy: NGC4784 is of a size of 1.2 "x 18" and an apparent magnitude of 15.0. NGC4781 and NGC 4784 are separated by 0.1 °.
The photo was also taken with a Meade DSI Pro camera, with frames of 1 minute of exposure.
