NGC 2237 - 21.2.2017 at 22.00 Paimio Observation number 61429

Visibility IV / V

Jani Laasanen, Turun Ursa

The unicorn beauty, Rosettesumu, has long been on her own winter shooting list. After Orion's sites, I finally got to this on a nice, ballgy evening. The background of the fog is just so full of stars that handling is exceptionally challenging when shooting with common sense.

      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.

Ihan hienoa jälkeä järkkärillä kuvatuksi.

Tosi hieno kuva: antaa uskoa järkkärinkin mahdollisuuksiin kuvauskäytössä
