From the bottom of my Soul

New imaging project, IC 1848, the Soul Nebula. This season I have worked with a longer focal length instrument, my old Meade LX200 12". This image shows a detail from a much large Nebula complex.

Soul Nebula (Sharpless 2-199, LBN 667) is emission nebulae in Cassiopeia at a distance of 7500 light years. The object is more commonly called by the cluster designation IC1848.

This complex is the eastern neighbor of IC1805 (Heart Nebula) and the two are often mentioned together as the "Heart and Soul".

A mosaic
I have shot an other detail from this nebula complex back in 2009. This new and older detail are overlapping, so I was able to do a two frame mosaic out of them.
