The Large Magellanic Cloud - 30 October 2022


The Large Magellanic Cloud is a companion satellite galaxy of our Milkyway 163,000LY away and only visible from the southern hemisphere.

Imaged at 150mm focal length through an Sigma 150mm f2.8 prime lens and exposed in HaLRGB using two cameras, a QHY268M astronomy camera for the luminance and H-Alpha signal and a stock unmodded Canon 40D DSLR for the RGB color data.
The reason for using the DSLR was to save time, capturing all of the RGB signal simultaneously as opposed to capturing the red, green and blue subs separately. The noise level and overall image quality of the RGB data was not much of a concern as long as there was color data with in the signal, as I only used it to colorise the luminance channel.

Guided with an 80mm refractor at 500mm FL and tracked on a hypertuned CGEM mount.

Total exposure time was 7 hours and 23 minutes.
