Description

This is a 6 pane mosaic encompassing some of the more well known areas of Orion - including a portion of Barnard's Loop down the left, IC 434, M42 and M43 to name just a few.

The data for this wasn't great and I'm amazed I have as much as I do.  The sky conditions on the 22nd January were poor.  Knowing this would be a big mosaic that was going to get resized, I removed the really poor subs, but still left in a lot of questionable stuff.

A few panes fell foul of the conditions more than others and have a noticeable drop in SNR.

Thanks for looking.

Description: Resampled to around 10-15% the original mosaic and about a third the size of the main version here. With that increase in SNR, it was pushed much further... at the cost of any detail of course!
