Description

Captured a couple of nights ago on the 27th - and some Ha planned tonight to bring out the narrow red band arcing away from the blue reflection nebula of Ced 201 (just visible in the image if you use your imagination). Cepheus has been a fabulous study for me this summer season with this third image from the dusty constellation - thoroughly enjoyable. I must brace myself for a large mosaic of this area - it is packed with interesting dust, dark and reflection nebula.

I've let the stars halo a little to emphasise the faint dust in the area which is seen often in web images and to preserve the translucent effect. It isn't straightforward to lift the dust from the background noise when deliberately working form a limited data set, so I'm pleased with the results.

Revision B: additional data added and completely reprocessed
Revision C: small boost to saturation
Revision D: small tweaks
