Description

My first attempt at a 3 panel mosaic, trying to get the Tarantula in its wider setting of the LMC... could probably do with adding a few panels; might add in future...  it's a fairly low object during much of my imaging window and seeing makes a big impact... I dumped over 8 hours of poor seeing subs for the ~24 hour total here ...but spread over the panels I guess more like 8 hours per panel.

I continue to be impressed at how well my little CEM40 mount is managing this load.

As the brightness of the Tarantula core is extreme I actually did this at 0 gain for full well depth and 4 min exposure...still some slight over exp but most detail preserved. 

Stacked the mosaic in APP which does seem great for mosaics after playing around with settings can do with nil join lines etc.

Took stacked channels into Startools and recombined binning at 50% for both Signal improvement and to bring down processing time.

Final tweaks in PS.
