Swan Nebula (M17) from a DwarfLab Mini

Capturing the details of the Swan Nebula (M17) turned into a tense game of peek-a-boo with fickle summer clouds, but managed to pull this off from 58 min data.

Target: Swan Nebula (M17)
Optics/Camera: DWARF LAB Mini
Mount: Equatorial (EQ) Mode on tripod
Filter: Built-in Duo-Band (H-alpha / O-III)
Sub-Exposures: 116 x 30 seconds (58 minutes total integration)

The raw FITS data underwent a modern starless/recomposed pipeline to isolate the delicate emission structures:

Calibration & Pre-processing: Initial calibration and SCNR cleanup in SIRIL.

Gradient Removal: Linear background extraction via GraXpert.

Star Separation: Starnet within SIRIL. Recomposed from within SIRIL.

Stretching & Recomposition: SIRIL, GIMP
