NGC 300 is a beautify spiral galaxy in the constellation Sculptor. It has an apparent magnitude of 9.0, making it the brightest of the five main spirals in the Sculptor Group. It has an apparent size is 21’.9 X 15’.5. For reference/scale, our moon is around 31’ arcmin across. It is approximately 6 million light years away. It is likely that NGC 300 and NGC 55 are a gravitationally bound pair.

Like NGC 55, there are many star forming areas. They can be located but the Hydrogen rich areas. These are the red coloured areas within the arms of the galaxy.

This was an interesting image to process as I have attempted to combine data from two cameras. Both have very different behaviours, making the calibration and data rejection a little challenging. But in end, I’m happy :)
