Description

A real struggle with this two panel mosaic generated from the Sigma 105mm.  The left panel contained more than a third more integration time than the right.  And really the whole thing is again starved for data.  I have never failed to generate a mosaic from the traditional methods (doing so prior to stretching), at least ones that I have learned through the PI tutorials.  Failure after failure this time.  Some of which had to do with difficult gradients.  Others from just plain failures of the image registration, dnalinearfit, and mosaicing functions. So I gave up with the traditional approach and processed each panel well through the stretch phase and even through significant star reduction.  It is then that I did the panel matches and final stretches by eye.  Only then did I get a decent registration using the mosaic by coordinates (Standard registration - mosaic failed badly).  At least Gradient Merge Mosaic did a decent job this time.  Still small patches of strange colors remain, etc.  But I think that this wide field gives a good idea of the relationships of some well known objects to each other.  I had done LBN 437 before, getting a good result upon reprocessing of the data.  I had also seen a wider field of view and was impressed by the dramatic smooth drapery of Sh2-126 and wanted to get that in full context.  Here I did.  But really in a much wider field than necessary.  I would really want to eventually settle onto a narrower frame for Sh2-126 and LBN 437.  Along the outer edges of the denser parts of the Milky Way, this field is probably most striking for the transparancy of all the features.  Only of the few densest parts of the IFN features seem capable of having star-forming going on, if that.

Not much more that I have the energy to state, with a balky computer (I think the latest Windows update has screwed up my computer) and the real struggle with getting something decent out of this.  Once again, short on data and struggle with this lens makes this a poor candidate for pixel peeping.
