Yeah I agree - the painted look comes from a range of dynamic masks (about 15 to 20 from memory) trying to reduce the core - 30 min for faint brown outlying dusk down to 5 min so far. I'd have to use pixinsight or similar for a HDR processing tool if I was working up a concentrated M42 image. As I said at the start - forget the image - its rubbish - (would have been happy with it back in the film days but). This forms a small part of a mosaic of the sword to the belt and in that context it works without having an over exposed M42 white blob in the wide field. Even colour saturation is based on the mosaic for uniformity.

yeah its the depth of field concept that impresses mne. the idea of sharpness at the front and softness at the rear with the degree of softness increasing the further you go back (and vice versa) - a lot of astroimages are just compeltly 2D with even sharpening (or deconvolution) over the whole field and while that was ok I think Crawford is starting to take it to the next level - Just wish I had his ability. The HHead is another example i would luv to see him work up. The faint brown dust underneath it should be at the front, B33 next going back obscuring the HII region at the rear.

This is a bad example I agree and the low res makes it even more so but if you look at Ken Crawfords stuff you'll see what I mean. I am particularly impressed with the large blue planetary he has processed for DOF.

I'll be out there Troy so come up and say hello
