Elefantin kärsä, IC1396 - 30.12.2018 at 18.30 - 30.12.2018 at 22.30 Rovaniemi Observation number 79997

Visibility V / V

The saying of the old people, " Keli is the one who pulls the load," is also true in astrography. If the weather is favorable, then taking a good picture will be easier.

The whole day was clear and I had adjusted the equipment to the backyard in good time for shooting. The clear dark sky lasted four hours, which was great enough to expose this subject. The hardware also worked well.

Since it was known that the material was of high quality, I correctly took all possible corrections. With PixInsight, I did stacking, color correction, background balancing, and noise reduction. In Lightroom I made the rest of the adjustments. Unlike usual, I chose yellow-orange as the main color of the picture, and I also slightly emphasized the elephant itself because of its spectacularness. I am particularly pleased with the fog appearing in black in the background.

      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.


      Emssion nebulae in Cepheus. The bigger part is composed of the nebulae Cederblad 214 (Ced214) and NGC 7822. The lower round nebula is called Sharpless 170 (Sh2-170). Image J-P Metsävainio.

      In this 4-degree-field there are emission nebulae Sh2-157, Sh2-158, Sh2-159, Sh2-161 and Sh2-162 (or NGC 7635 aka Bubble Nebula) and open clusters M52 and NGC 7510. Image Juha Kepsu.
