Cygnus Wall and Eagle Narrowband

Not in the same shot I hasten to add.  Ambiguous weather forecasts normally end in tears, but last night was a welcome exception.  Four clear hours over the Malvern Hills, with an isolated, dense, and uncannily static cloud shielding the rising moon, gave me 2 hours each of SII and OIII to brighten up last week's Ha data on the Cygnus Wall.   Also here my first wide-field on the Eagle (with the Esprit 100 rather than C9.25, insert from which included in the pic) - which is always a blood-from-stone affair for me due to a very narrow window of visibility between trees.  Only funny on these was the SII data for the Cygnus Wall, where there was mystery rotation between subs - but not on the OIII in the same session? - which I think has somehow slightly thrown the final registration; maybe something coming loose.  Anyhow, both classic, beautiful, targets.

EDIT: A version with the registration/alignment fixed is posted in the comments below.

Of course, you always sort out the unfathomable errors immediately after posting.  For good order, here's a version of the Cygnus Wall with the registration/alignment error corrected.
