Iris Nebula

NGC 7023, known as the Iris Nebula, is an area of brownish dark dust in the Cepheus constellation - illuminated brilliantly in the centre by an intensely bright, blue young star SAO 19158. According to NASA, this area attracts study because of its unusual prevalence of Polycyclic Aromatic Hydrocarbons (PAHs), complex molecules found on Earth during the incomplete combustion of wood fires.

My picture comprises 746 x 20" exposures at ISO 1600, imaged from Colchester, England, on a modified Nikon D750 DSLR, Sky-Watcher Explorer 150p, EQ5 Pro, via Stellarmate in Kstars/Ekos. Stacked in AstroPixelProcessor, cropped and adjusted in Photoshop and Lightroom.

Tulip Nebula

The Tulip Nebula, catalogued as Sharpless 101 (Sh2-101), is an emission nebula in the constellation Cygnus. My picture comprises almost 700 x 20” exposures at ISO 1600, imaged from Colchester, England, on a modified Nikon D750 DSLR, Sky-Watcher Explorer 150p, EQ5 Pro, via Stellarmate in Kstars/Ekos. Stacked in AstroPixelProcessor, cropped and adjusted in Photoshop and Lightroom.

The Western Veil with the bright foreground star 52 Cygni, and (lower left) Pickering's Triangle. My picture comprises just over 1500 x 20” exposures at ISO 1600, imaged from Colchester, England, a few days ago on a modified Nikon D750 DSLR, Sky-Watcher Explorer 150p, EQ5 Pro, via Stellarmate in Kstars/Ekos. Stacked in AstroPixelProcessor, cropped and adjusted in Photoshop and Lightroom.

Sadr. Cygnus. Milky Way. From my back garden, with a full moon and very short nights.

This is the Crescent Nebula in the constellation of Cygnus, photographed over four nights in May 2023. NGC 6888 is the result of the outer layers of the old star at its centre - known as a Wolf-Rayet star - being blasted out by a powerful stellar wind. The shape that we see is about 25 light years across and 5,000 light years away from Earth.

My picture involved 9.5 hours of sub-exposures plus calibration frames, taken in Colchester, England, on a modified Nikon D750 DSLR, Sky-Watcher Explorer 150p, EQ5 Pro, via Stellarmate in Kstars/Ekos. Stacked in AstroPixelProcessor, cropped and adjusted in Photoshop and Lightroom.
