Description

With the 2022 grantwriting season done, I can catch back up on my astro posts. :-) 

This tests the new built-in mosaic planning in the ASIAIR, as a 6-panel plan on the Elephant Trunk Nebula and region. I found stitching this mosaic together was much more challenging than expected: because so much of the panels are filled with nebulosity, Astro Pixel Processors' normalization had a hard time getting it right. I ended up using LNC (degree 1, 4 iterations) and a lot of finesse in the gradient removal tool, but it came together. 

As most dual narrrowband mosaics, I extract and process Ha and [OIII] in each panel separately, form Ha and [OIII] mosaics, and then combine in HOO. 

The first image is shown at half resolution, but all work was done at 1.2"/pixel with my AT115EDT, with no star reduction, and light denoising and touchup in noiseXterminator and Topaz.

The other images show full resolution details on regions of interest. I hope you enjoy! I'll definitely need to revisit next summer when it's higher in the sky!
