Another relatively quiet month for deep sky observers; three section members submitted seven images in total.
Alan Clitherow, SPA Planetary section director, observing from Fife, imaged emission nebula IC 1396 in the constellation of Cepheus using a Williams Optics 66mm refractor and Canon 600D astro modified DSLR.
At the 3 o’clock position in this image is the object known as the Elephant’s Trunk nebula (NGC 1396A), which is a region of new star formation: some of the stars here are only around 100.000 years old. The whole nebula is being illuminated and ionised by the massive star HD 206267.
Next is Alan’s image of M27, the Dumbbell planetary nebula in Vulpecula; using on this occasion a MN190P Maksutov Newtonian reflector and the same camera.
Steve Norrie, also of Fife, sent in four images, using an ES 127mm f7.5 refractor and Starlight Xpress Trius 694 mono camera and narrow band filters to produce the “Hubble” palette.
First is emission nebulae IC 1805 the Heart nebula then NGC 281 the Pacman nebula, both in the constellation of Cassiopeia.
NGC 6960 is the Witches Broom (a portion of the Veil supernova remnant in Cygnus) and NGC 7380 the Wizard emission nebula and open cluster in Cepheus.
David Davies of Cambridge imaged M57 the Ring planetary nebula in the constellation of Lyra, using an 8″ Ritchey Chretien telescope, QSI 583 mono camera plus red green and blue filters.
As a postscript, I too imaged M27 and M57 during September, using a 305 mm SCT at f6.3 and an Atik One 6.0 mono camera. These images are L(OIII)RGB.
