Prudhoe, Northumberland

For RGB data – Canon EOS1100d, Tamron 55-200mm lens, HEQ5 Pro mount, Astronomik CLS clip filter.

This is part of a wide-field image of a region in Cassiopeia that I took back in September with a DSLR + lens. I recently re-processed the image by cropping it & adding Ha data of the Heart & Soul nebulae took with my telescope last year. The nebulae is now much enhanced and competes with the star field where it didn’t before.
