M42 - 15.2.2015 at 19.00 Pori Observation number 33614

Visibility IV / V

At last the clouds receded from the sky. I took Orion's gas fog, there were problems with the focus, but a moderate picture nonetheless ... The subject was more exposed than this one about 1min 9sec. ISO 800, Pipe SW 200/1000 (f5) Addition: March 2, 2015 I practiced stacking with Registax software and image processing as a result of 2 images with a total exposure of about 10 minutes.

      In an emission nebula the hot stars nearby cause the gas glow. This should not mix with reflection nebula, where the gas is only lit up by nearby stars.

      The appearance of a gas nebula is irregular, and the fainter parts of it need bigger instruments to be visible.

Pinoamaton kuva omasta mielestä parempi... Tuli kenties himmennettyä kuvaa liikaa?
