Hi Folks,


With Orion disappearing in the West I thought I'd capture it before it was gone for another season.

Great image. This season seems to be flying by with very few clear nights to show for it!

James, Kathleen & All,


Many thanks for the kind comments. The Horsehead has a Beechers Brook in the field with Alnitak being so bright so keeping that under control without a halo is never easy. The diffraction spikes can be a real pain as my scope spider vanes are 0.7mm thick which makes the spikes long and disruptive on some images. In this image they went well off the image but I've cut them back. Thick vanes on the other hand  push the diffracted energy inwards leaving short thick spikes but resulting in squarish stars.  I've got some Ha data on this target but I'm not a fan of adding it as it tends to wash out other colours, I'll see if I've got an example and post that.


Graham.
