Tarantula takes two tiny steps

The very beginnings of what might be a long project - a 0.55 sec arc/pixel mosaic of the greater Tarantula region.

High res original here.

So far, due to weather, we have just the top central frame and one about a third of a frame bit below it. Hence the framing looks a bit odd, as we plan to add many more frames to left, right, and down, but not up.

Only one hour per channel per frame so far, so statistical data rejection is impossible.

Supernova 1987a is marked, toward the bottom right corner.

Placidus Palette: Hydrogen alpha unashamedly mapped to yellow and OIII to blue. Star colours not modified. No noise reduction.

We rather like the structure at bottom left, which from one point of view is an Aladdin's cave filled with jewels, and from another is the gaping jaws of a fierce taipan coming to eat the astronomer.

Aspen CG16M on 20" PlaneWave. As usual, all image processing software including the mosaic construction is written by Mike. Consequently this shot is something of a proof of concept.

Best,
M & T
