About this image

One of the most photogenic parts of the sky... The very best  pictures of this area show structure in the dark nebulosity below the horsehead... I just have a suggestion of this with a vague mottled effect. However, there is some nice structure in the emission nebula (IC434) that is the backdrop to the horsehead. This emerged after some use of the local histogram tool in Pixinsight... but more detail would require  better data, I think, from a good dark sky (not suburban Sheffield).
