A strange irregular planetary nebula.

This planetary nebula is called NGC 5189.
It is in the constellation Musca, at 24 ° of the south celestial pole.
It looks like a barred spiral galaxy. This irregular shape is the result of the gravitational action of a nearby star of the exploded star. Its aparent size is 3 minutes by 2 minutes
Were 59 frames of 1 minute exposure at ISO 1600. Were processed with Deep Sky Stacker, Photoshop and Pix Insight.

New Eta Carina Nebula

This photograph of this magnificent nebula in the constellation Carina was acquired on March 16, 2013.
It is the result of 47 frames, 20 darks, 20 flats and 20 offsets.
We used the same telescope. We used the modified Canon 450D camera and a Celestron antipollution filter.
These are pictures taken at ISO 1600 and with an exposure of 1 minute.

A new process of a picture of the Tarantula Nebula.

With photos taken on February 12, 2013 I made this rework.
This time I used the "auto white balance" in the program Deep Sky Stacker.
Also I used "star mask" for stars.
I think this is better than the last.
