My Take on M33: Unveiling the Triangulum Galaxy

This post showcases a stunning rendition of the Triangulum Galaxy (M33), a fascinating spiral galaxy located about 3 million light-years away. Captured under Bortle 3 skies during a first-quarter moon, this image is the result of dedicated acquisition and meticulous processing.

Triangulum Galaxy

Acquisition Details:

  • Camera: Canon Rebel T7
  • Telescope: Redcat 51 WIFD
  • Mount: IOptron Skyguider Pro (with WO Wedge)
  • Exposures: 240 x 45-second lights at ISO 1600
  • Calibration Frames: 30 darks, 30 flats, 30 bias
  • Sky Conditions: Bortle 3
  • Lunar Phase: First Quarter Moon

Processing Workflow:

The journey from raw data to this final image involved a two-stage processing approach, leveraging the power of Siril and Affinity Photo 2.

In Siril, the following steps were performed:

  • Color Calibration
  • Background Extraction
  • Image Stretching
  • Saturation Adjustments

Following Siril, the data was refined in Affinity Photo 2 with:

  • Star Reduction
  • Noise Reduction

This combination of techniques allowed for the enhancement of the faint details and vibrant colors within the Triangulum Galaxy, resulting in a visually striking and scientifically informative capture.
