NGC 2392 - 21.2.2019 at 00.00 - 21.2.2019 at 02.30 Ulvila Observation number 81284

Visibility Unclassified

We were at the Ulvila observatory to test the new tripod and get better acquainted with the camera of our association and the operation of its control software. During the training session, we imaged the Eskimos of the Twins (NGC 2392) with LRGB filters. Here is a single frame through the red filter. Image grooved, north bottom, west left. Calibration images reduced from the image, and it is stretched and saved as jpg, plus the contrast is slightly adjusted. Final color image coming later!

      Planetary nebula is the remnant of a death star. It could be ring-shaped, disc-like or spread out rather irregularly.

      With the exception of some nearest objects planetary nebulae have a small apparent diameter and they need a rather big instrument to be visible.

Kyllä ja loppukuvasta tulee epäilemättä hieno.
