a starless version of the Veil Nebula.

The Veil is the visible part of the Cygnus Loop, a massive supernova remnant and radio source around 2,400 light years from Earth. The original star was likely 20x the mass of our Sun and exploded around 10,000 years ago. It has expanded to cover a sky area approximately 36x the area of the full Moon.

There are a lot of stars in the field of view so I used a tool called StarNet++ to remove them and reveal the gases (Hydrogen = Red and Oxygen = Green) more clearly. This is so large that different areas have their own names. The Western Veil (on the right in this view) is called the The Finger of God or The Witches Broom.

The Horsehead and Flame nebula. by HGSAS Member Callum Wingrove in November 2020. Callum said at the time.

"I had to include this as it’s one of my favourite areas of space to photograph and its back in the sky at the moment until February. As soon as we get a clear sky I will be trying to image this and the adjacent Orion Nebula with my wide field scope and create a mosaic of the two. The bright star is Alnitak, the left most star in the belt of Orion.

I am starting an Astronomy Photo of the Month Section for Members to show some of the images that they have produced.
Callum Wingrove has kindly started us off with a fabulous selection of his recent photos.

This month is the Soul Nebula (IC 1848/IC 1871), an emission nebula located to the East of the Heart Nebula (IC 1805) in Cassiopeia around 6,500 light years from Earth. This is a ‘Hubble Pallette’ image, also known as SHO (Sulphur Hydrogen Oxygen) shot with a mono camera in late September. Blue is Oxygen, Yellow is Hydrogen and Red is Sulphur.

We now have a full programme for 2020. I have just booked Callum Wingrove for 27th May. He is one of our members and has taken some breathtaking shots of the night sky from London, which he will be showing us and on 24th June Roger O'Brien will be talking to us about Lunar Cycles which will be particularly relevant as unusually there are lunar eclipses on 5th June and 5th July next year!
