The Moon from last night. This was made from a mosaic of images from a Meade LPI webcam-type imager. The image processing for this was rather involved.
The software from the Meade LPI puts out RGB FITS files. The ~1600 individual files had to be separated into their red, green, and blue components for processing. This was done on a Mac in IRAF.
The now ~4800 images were then transferred to a Windows machine where the program Registax was used to create 6 images covering the Moon in R, G, and B. Registax registered the images, threw out about half due to quality, then combined and processed the images for sharpness.
Finally Photoshop was used to bring the R, G and B mosaics together into a single colour RGB image.
These 18 processed images (6 each in R, G, and B) were then transferred back to the Mac for processing in photoshop. Photoshop merged the 18 images into three mosaics, one for each of R, G, and B.
