This 81 megapixel giant moon picture has been making the rounds and according to DIY Photography:
This image was acquired by taking 50,000 images of the lit surface (25 tiles at 2000 frames each) and stacking the best 50% of the frames. Acquisition was done with a ZWO ASI224MC. The earthshine portion of the moon was captured with a Sony a711, and was a mosaic of 13 tiles with the best of around 20 images per tile stacked. The stars were taken with a stack of 50 images with the Sony. The telescope I used was an Orion XT10, mounted on a Skywatcher EQ6-R Pro.
It works great as a background image.
