Your eyes may be naturally drawn to the huge and colorful Seagull Nebula… but did you also spot the much smaller Thor’s Helmet on the bottom right? Don’t be fooled, Thor would totally win in a space fight against a seagull 🐦⚡️ 😅

 

This is my LONGEST integration time to date… 61 hours!

I beat my previous record of 48 hours of exposure with this image by spending many, many nights on it.

 

This was very challenging to do because this target was only available for 5 hours max from my backyard. It would be high enough around 8PM, then get behind trees at 1AM. I only have narrowband filters in my filter wheel and this is the last large nebula in the sky so after 1AM each night, the scope would just sit there doing nothing. But it was WORTH IT!

After 12 nights… and long hours of stacking and processing, this is the result!

 

The Seagull Nebula is known as IC 2177. It is a large nebula that can be found 3,650 light-years away in Monoceros. It is a great target for both broadband and narrowband imaging, and is very close to the much smaller Thor's Helmet Nebula.

 

If you look closely near the Oxygen gases of the Seagull Nebula, you should be able to spot a bright star with a strange arc-shaped line of gas just above it. This is commonly known as the "Bow shockwave" in IC 2177. It is believed to come from the interaction between the interstellar dust within the nebula, high radiation winds, and gas expelling from the double star system "FN CMa”. The exact origin is still not very clear, but we might learn more about it in the years to come!

 

Thor’s Helmet is known as NGC 2359. It is a cloud of interstellar gas, although very faint, the colors in the gases really pop when taking long exposure shots with any camera.

This beautiful deep-sky object gets its glow from WR7, a massive Wolf-Rayet star that will soon turn into a supernova.
