NGC 7635 - 12.3.2019 at 21.00 - 12.3.2019 at 23.00 Pori Observation number 81705

Visibility II / V

Jarkko Suominen, Porin Karhunvartijat

I was spotting a deep sky in the Pori Prefecture with great weather. Originally I had to describe the environment of M86, but when I got there I realized that the target is in that light pollution of Pori ... So I had to think of another target and Bubble Nebula was chosen as my target.

The hardware was recently collimated, so at first it took time to refine, etc. Next, of course, the newly charged batteries started to clot, so I put them in my pocket to warm up and yes, there came a few more minutes of it XD. Some of the pictures were ruined due to occasional cloud rafts and the rest of the evening the fog rose to bother.

At home, I noticed that the stars aren’t quite round ... the mistake is repeated in every picture, this time the project of the following evenings.

      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.

Hieno kuva Jarkko, vastoinkäymisistä huolimatta! :)

Kiitos, Tomi. Pakko kyllä todeta, että olisin halunnut kuvailla sitä M86:tta, mutta ihan kiva, että tuli tätäkin kuvailtua. Olisi saannut olla kyllä reippaasti enemmän valotusta.
