Description

This is a 6 panel mosaic of the Horse head and M42.

Processing was done in PI and PS.

Matching the frames proved more difficult than normal due to a huge variation in signal to noise between frames, but I'm happy with the final product.

Unfortunately getting colour data for this target is almost impossible from my location, but would love to add it eventually.

As always C&Cs are most welcome. Thanks for looking.

Description: Starless version: I'm not sure if I like this version, but I uploaded mainly because of the amount of work I put into removing the stars.
