C49 - Rosette Nebula - DSLR - 2021-03-12
The Rosette Nebula in Monoceros is an active stellar nursery from which the stars in cluster at its center, NGC 2244, were born. This image was a bit of an experiment and was taken using a 300mm f/4 lens (rather than a telescope) stopped down to about f/5 using filter reducing rings instead of the internal aperture blades to improve sharpness while avoiding diffraction spikes.
Camera: Full-spectrum modified Nikon D5300
Lens: Nikon 300mm f/4 (externally stopped down to ~f/5)
Mount: iOptron iEQ45 Pro
Integration: 70 minutes (14 x 5 mins)
Post-Processing Software: PixInsight 1.8.8, Corel Paintshop Pro
Captured under dark skies near Goldendale, WA
