We now have the first two adjacent panels of the initial 3 x 3 mosaic planned for the whole Orion Nebula and Barnard's Loop. Panels 18 and 23 (Panel 18 is labelled 10 in the list of datasets - an error on my part). We have a couple of other panels, but they only touch at corners so I haven't used those yet.
The attached is a very early process - just to see if things are working out.
Each panel was stacked followed by DynamicBackgroundExtraction, HDRComposition (60 and 240 sec masters) PhotometricColorCalibration (because I haven't got the new spectral version working yet), EZ Denoise, and forming the mosaic using MosaicByCoordinates and PhotometricMosaic. Finally, a MaskedStretch to see what we have.
No other processing or enhancements, so in principle a lot more to come.
As you can see the Trapezium is saturated. We could do another run at 15 or 10 secs to dig that detail out if you think it is worthwhile.
But apart from that, are you content with the data we are getting? Are you happy to let the rest of the 3x3 mosaic continue (panels 11-13, 16-18, 21-23), or should we abandon the project or gather more data?
