M42 the Great Orion Nebula by Sara Wager Via Flickr: The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 light years approx and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula The Orion Nebula is one of the most scrutinized and photographed objects in the night sky, and is among the most intensely studied celestial features.[8] The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula. ​Details M: Avalon Linear Fast Reverse and Mesu 200 T: Takahashi FSQ85 0.73x and AT 8" RC CF C: QSI690-wsg with 3nm Ha filter and Hutech IDAS filter, QSI683-wsg with Baader red, green and blue filters 14x1800s Ha (FSQ85) 16x45s Ha (FSQ85) 79x40s Ha (2x2 bin AT 8" RC) 31x600s Lum (FSQ85) Red - 50x300s (FSQ85), 15x10s, 20x60s Green - 50x300s (FSQ85), 15x10s, 20x60s Blue - 50x300s (FSQ85), 15x10s, 20x60s There is a total of 26 hours, 32 minutes and 10 seconds

An artistic impression of NGC2237 (The Rosette nebula) by Sara Wager Via Flickr: An interesting title you may think and you may wonder why I have written artistic impression........ Firstly let me say that the raw data for this 'experiment' is all mine and has been recently acquired. There is nothing new there. What I have then done is considered the processing and have coined a term 'Monochrome channel mapping'. What this means is that this image has been 'created' using ONLY Ha data, there is nothing more in there. This is an experimentation processing technique that will horrify some and perhaps please others that this can be obtained by only having to acquire Ha data - In fact lets not be so prescriptive, the same could be done with any single filter data if the signal was sufficient. So I hope that you enjoy this experiment and the debate that it may bring within yourself. I hope that I won't get burnt at the stake for heresy........ Details M: Avalon Linear Fast reverse T: Takahashi FSQ85 0.73x C: QSI683 ws-g with Astrodon 3nm Ha filter 39x900s in Ha totalling 9h45m of exposure.

NGC7000 and IC5070 - The North American nebula and the Pelican nebula by Sara Wager Via Flickr: The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus. The remarkable shape of the emission nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico. The North America Nebula is large, covering an area of more than four times the size of the full moon; but its surface brightness is low, so normally it cannot be seen with the unaided eye. The North America Nebula and the nearby Pelican Nebula, (IC 5070) are in fact parts of the same interstellar cloud of ionized hydrogen. The distance of the nebula complex is though to be approx 1800 light years away.

NGC7023 and VdB141 (Iris nebula and Ghost nebula) by Sara Wager Via Flickr: The Iris Nebula (NGC7023) is a reflection nebula approximately 1300 lighty ears away, located in the constellation of Cepheus. On the right hand of the image is VdB 141 (The ghost nebula) so called because of it's shape. This is also a reflection nebula and is about 1500 light years away. Details: M: Avalon Linear fast reverse T: Takahashi FSQ 85 C: QSI690ws-g with Lum filter and Starlight Express Trius SX25C OSC for the colour.

DWB111 - The propeller nebula in bi colour. by Sara Wager Via Flickr: A faint emission nebula located in Cygnus. There is no information about the distance of this nebula. This is a 2 pane mosaic so that all of the delicate dust is captured as well, using an Ha and OIII filter to create a bi colour image. Details: M: Avalon Linear Fast reverse T: Takahashi FSQ85 0.73x C: QSI690ws-g with 3nm Ha and OIII filter Pane 1 - 11x1800s Ha, 10x1800s OIII Pane 2 - 10x1800s, 9x1800s OIII Totalling 20 hours of exposure time.
