The Andromeda Galaxy is one of the most photogenic and a subject I return to many times.

For more information on the Andromeda Galaxy. See post https://petesfavouritethings.wordpress.com/2013/03/01/

These photos taken using the of NASA telescope.

Sometimes it is difficult to see how a nebula or other body got its name but I really think these photos look like a swan

The Swan nebula (M17/NGC6618) is also known by a number of other names such as the Omega Nebula, the Horseshoe Nebula or the Lobster Nebula. It is 5000 to 6000 light years from Earth and has a diameter of 15 to 20 light years. it is one of the brightest and most massive star-forming regions seen from Earth and is visible with binoculars in the constellation Sagittarius.

Not done much astrophotography recently but here are two pictures of moon taken in December last year

NGC6960 sometimes known as the ‘witches broomstick’. Here are a couple of not terrible successful attempts by me to photograph it. The presence of a bright object alongside it makes the duration of the open shutter problematic. I  tried doing longer shots but the nebula just gets blotted out by the bright object.

Here is another much more successful picture of the whole nebula, which shows how it became to be known as ‘the witches broomstick’

This nebula is part of the Orion Nebula complex and is seperated from the main nebula by a lane of dust.

Located in the constellation Triangulum, from which it takes its name, this spiral galaxy is the 3rd largest after the Milky way and the Andromeda galaxy. It may be a bound satellite of the Andromeda galaxy. It is 3 million light years from earth; has a diameter of 60,000 light years and is estlimated to contain around 40
billion stars.

I was interested to read on EarthSky about this years Harvest Moon. The Harvest Moon is the nearest full moon to the autumnal equinox and often brings about early evening moon-rises and so is much beloved of photographers. It sometimes has interesting effects and can look bigger than normal or appear more colourful.

This year’s harvest moon will occur on the 8th or 9th September depending on your location. So check for your location and get your cameras out and go chase that harvest Moon.

Here are a series of photographs taken recently of the Orion nebula using different filters on the camera.

The infrared filter blocks are all light in the infrared spectrum and can reveal details which otherwise would remain hidden by infrared light.

The H alpha filter only allows light through that is generated by Hydrogen atoms emitted energy.

The OIII filter is recommended for photographing Nebula as they are designed to provide higher contrast views of deep sky objects
