Tarantula mosaic complete

Our first completed 6 panel mosaic. 32 hours total exposure.

Here it is.

H-alpha + OIII, 16 hours each, in Placidus Palette (H-alpha = yellow, OIII = blue).

No deconvolution or sharpening. We're not planning on making the stars white. They add a certain sparkle.

Apart from the lack of SII, our shot looks virtually identical to Slawomir's. I suppose that's a good thing - it means we're all photographing what's actually up there. (The framing is very slightly different).

We're reasonably chuffed at how our written-in-house mosaic software (Prometheus) worked.

Best, M & T
