Details
Canon 5DH. Canon 85mm F1.8, Hutech LPS filter, all at ISO500.

At f/2.8, 5X(2min, 4min)
At f/4 , 5x( 30s, 1min, 2min)

Converted from RAW to TIFF and corrected for flats with ImagesPlus. Stacked and aligned wiith Registar. Used EasyHDR to produce a LDR image from these five images.

If you look carefully you can just see the Witches Head Neb. at top right.
