Sh2-129 - 1.5.2021 at 22.00 - 2.5.2021 at 03.00 Salo, Särkisalo Observation number 98222

Visibility I / V

Jarkko Järvinen, Tampereen Ursa

I dare to put the first picture of the deep sky on display here after the training season. During six cloudless nights, Sh2-129, Outters 4, and VdB140 were recorded at 22h shutter speed. Filmed 14.4.-1.5. between the short nights of spring.

      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.

Ensimmäisen syvän taivaan kuvan? Jos näitä alkaa tulemaan lisää, joudun koodaaman Taivaanvahtiin sellaisen 'tuojottaa äimänkäkenä - vau!' -napin. :)

Tämän muotoutumista on saatu seurata.
Mutta aika kova avaus tosiaan.

Joo-o, onpa hieno otos!

Näitä kelpaa katsella ja odottaa innolla uusia mestariteoksia.

Hieno ensivalo.
