Description

This is a collaboration between Derek Morf and Jeff Newgard.  While we contributed equal data to this project, and processed collaboratively over video conference, Derek was the lead processor.  While there is a cumulative of 118h10m of data invested this project, there is 55h5m of data per panel, and thus 55h5m is the equivalent exposure time for the image as a whole.

We had been looking for a unique twist on a common target, and opted to tackle a two panel mosaic on the Witch Head, but in a panoramic view of the nebula instead of typical 2:3 or 3:4 image ratio.  Instead, we choose to portray this object by aligning the short sides of each panel to create a panoramic view.

We want to emphasize that our preferred orientation for this image is vertically, with the Witch Head protruding from the bottom of the frame and moving up towards the top.  We chose to present this laterally on Astrobin to better show the image within the confines of a webpage, but we recommend you review our revision of this image in full screen mode to see the preferred orientation.

This was our first 100h+ collaboration from Starfront Observatories, and won't be our last!  This also is our first attempt at combining some newly learn processing techniques in both PixInsight and Adobe Photoshop.

We'd love to hear your feedback on both the image ratio, perspective, and processing!
