Mosaic of entire moon - 7th Nov

I wanted to make large prints of the moon, but unfortunately my 924 mm focal length refractor + Canon 5DmkII combo only gives me a 1300 pixel wide image of the moon.

I decided to use a 5x PowerMate in order to capture the moon as a mosaic of six panels. Although capturing in movie mode, stacking and processing with wavelets would have been ideal, by my calculations I would have needed about 60 panels - too impractical for me. Instead, I captured 50 still frames for each panel, hand picked the best one for each panel, and merged the final six still frames in Photoshop.

The end result is that I now have a 6600 pixel wide image of the moon that looks fantastic as a 61x61 cm print. I've attached a downsized version and a 100% crop, but if you have a high resolution monitor the full 7500x7500 pixel image can be downloaded here:

It's obviously nowhere near the true/effective resolution of Dennis' magnificent efforts, but I'm pretty happy with the end result for my wall
