The original processing of this 1x3 mosaic, dating back to autumn 2022, was really difficult, and for a long time I had been meaning to completely rework it with the new PI tool PhotometricMosaic, which was not known to me at the time of recording (and perhaps did not even exist yet!).
The result obtained now is perhaps slightly better than
the original one, even if the data (taken with an uncooled DSLR) does not have the noise uniformity needed for a mosaic.
However, my take is that PhotometricMosaic, in combination with MosaicByCoordinates, is significantly more robust than PI's classic mosaicing tools.
A definitively positive, yet subtle, point in favor of PI is that the new PI ImageSolver has become so precise that now the stars match perfectly in the joints.
Technical comments and constructive criticism, especially regarding mosaics, are, as always, very welcome.
Sh2-126 Sh2-126 is a large and faint Hii region ionized by the OV9 multiple star 10 Lacertae (center-left in the image), which forms the core of the Lacerta OB1 association which is located at 520 pc distance (1700 ly).
The Gecko NebulaOn the top-right of the field is visible the famous Gecko Nebula LBN 437, rich of Herbig-Haro objects, that I imaged in broadband, and discussed in more detail,
here and
here.
