IN THE SKY THIS MONTH - (We photographed NGC 7635 - The Bubble Nebula)
NGC 7635, also known as the Bubble Nebula (for obvious reasons 🤓), is an emission nebula located approx. 8000 light-years away from Earth in the constellation of Cassiopeia
Although it looks quite small in the photo (as this is a wide field photograph) the Bubble itself is actually 7 light-years across, meaning if you started at one side of the bubble, it would take you 7 years travelling the speed of light just to reach the other side of the bubble (Lets put that into perspective, if you were travelling at the speed of light, it would take just 5.5 hrs to fly from Earth to Pluto).
Sometimes its really easy to forget just how huge some of these objects in space really are.
This photo was taken with the smaller TS94 Refractor but we currently have the larger TS150 Carbon Newtonian installed in the observatory so we're hoping (weather permitting) to photograph it again at a higher focal length to really see some more detail on the main bubble itself.
ABOUT THESE PHOTOS:
These photos were taken from our Horizon Observatory in Southern Germany using the following equipment:
- TS94 APO Refractor on a Vixen SXD2 Sphinx EQ Mount.
- Explore Scientific 16MP CMOS Colour Camera
- Filter: Optolong L eXtreme Narrowband Filter
- 180sec sub frames (Total exposure time 3hrs 30mins)
- Stacked & Processed in Astro Pixel Processor & PS
Hope you enjoy!
Wishing you Clear Skies 🔭🌌
