A William Optics Zenithstar 71mm doublet refractor fitted with a field flattener was used to image a couple of deep sky objects using an ASI 533MM Pro camera using LRGB and narrowband filters. Images were captured using NINA with integrations and processing completed in Pixinsight, Adobe Photoshop 2024 and Fitsworks4

The great Pegasus Cluster (M15): 40 mins of 30s LRGB subs - imaged on the night of 12th September 2024. M15 is an ancient globular cluster located in the constellation of Pegasus some 37,500 LY from Earth and is estimated to be around 23 billion years old. The cluster contains over 100,000 stars that have undergone core collapse that are suspected to orbit a central black hole.

The Crescent Nebula (NGC6888): 120 mins of 2 and 4 minute narrowband subs of Ha/SII and OIII - imaged on the night of 13h September 2024. Four different palettes were produced from the data to show the various gases more clearly. The Crescent nebula is an emission nebula lying some 5,000 LY away in the constellation of Cygnus. The nebula glows brightly due to gas left from when the star expanded into a red giant being heated by the current Wolf Rayet star's solar wind, resulting in two shells of gas with two shock waves travelling at different speeds interacting together.
