Shot this back in the spring and forgot it was sitting unprocessed on my computer until now. This photo has had the saturation increased to highlight the differences in the lunar soil, which are barely noticeable to the eye when viewed through larger telescopes (usually in Mare Serenitatis or Mare Imbrium for me, at least). Tan/orange indicates iron rich minerals, and blue indicates titanium rich minerals. Captured at early in the morning on March 29th, 2023.
