Capturing the Majestic Andromeda Galaxy (M31)

The Andromeda Galaxy

This past clear night, I had the opportunity to point my gear towards one of the most iconic celestial objects in our night sky: the Andromeda Galaxy, also known as M31.

A Glimpse into the Cosmos

The Andromeda Galaxy is our nearest major galactic neighbor, a spiral galaxy that is breathtaking to behold, even through a relatively small telescope. Its sheer scale and the millions of light-years it has traveled to reach us are truly awe-inspiring.

The Gear Behind the Shot

To capture this image, I utilized the following equipment:

  • Camera: ZWO ASI533MC Pro
  • Telescope: William Optics ZenithStar 61 II APO with Field Flattener
  • Filter: Optolong UV/IR Cut
  • Guide Camera: ZWO 120mm mini
  • Mount: Skywatcher Star Adventurer GTi

Acquisition Details

The imaging session took place under Bortle 5 skies, offering a decent darkness for capturing faint details. The camera was cooled to -10°C to minimize thermal noise.

Here's a breakdown of the acquisition data:

  • Lights: 113 frames at 180 seconds each, totaling 5 hours and 39 minutes of integration time.
  • Flats: 50 frames
  • Bias: 50 frames
  • Darks: 50 frames

Future Plans

While I'm thrilled with this initial capture, the journey doesn't end here! I'm planning to add more integration time to gather even fainter details and reduce noise further. Additionally, I intend to incorporate Hydrogen-alpha (Ha) data in future sessions, which will help bring out the vibrant red hues of the star-forming regions within the galaxy.

Stay tuned for updates on the continued processing and enhancement of this beautiful target!
