IC 434, NGC 2024 - 30.10.2022 at 00.08 - 30.10.2022 at 00.58 Janakkala, Tervakoski Observation number 110559

Visibility II / V

Petri Kuossari, Riihimäen tähtit. yhdistys

I tested Vespera's "panorama" mode, it allows you to explore a much wider sky than Vespera's original field of view. The Vespera benefits from the ability to capture images at a higher resolution than the sensor resolution, up to 8.2 megapixels thanks to the mosaic mode. Normally, an image is 1920 x 1080 pixels, but for example this image of Horse's Head and Flame Fog is 1920 x 4091 pixels

I cropped the first picture a bit, changed the tones a bit in the second one, the third picture is the original, from which you can see that the mosaic was not quite finished yet, the tree came threateningly in front, so I stopped the shooting.

      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.
