The imaging is finished for now. The data is excellent and deserves to be experimented with in processing. The RGB stars also need to be implemented.

Notes

January has been a better month for clear skies making astro imaging possible once again. Hooray! M78 in Orion is a reflection nebula approx 1600 light years from Earth with NGC2071 to its North. Also visible is part of the H-Alpha cloud known as Barnard’s Loop which encircles the left-hand/East side of the constellation. Barely visible on following the line of the dark lane in the centre of M78…
