LRGB image by Dmitry Makolkin, Moscow, Russia

All of the recent spacecraft that orbited the Moon carried multispectral cameras that captured images through a variety of filters. The purpose was to detect and map areas with subtle differences in color which represent differences in surface composition. Dmitry has achieved a similar goal with his excellent composite image made by blending a high resolution luminence image with an RGB one. His original full Moon Chuck Wood

Technical Details
9 September 2009, ~03:30 MSK (GMT +4h). TAL-250K 250mm F=2130mm.
L channel: camera DMK 31, filter - Astronomics IR Pro 742, 36 AVI, 2500 frames each, stacked 350 best frames in Registax 5 and Avistack. Then panorama was created, deconvolution and tonal correction were applied.
RGB was taken with the same scope and 0.7x compressor, so the whole Moon was on the frame of Canon 350D. 128 of 160 CR2 images were stacked in Registax 5.
Final image was assembled from IR image as L channel, color information was taken from RGB image. To match the scale of L channel, RGB image was resampled to 2x bigger scale.
