Description

This one has been on my list for a long time. Capturing the sheer amount of galaxies available in this area of sky was a surprise even when I expected them to be there. Makarian's Chain is near a galactic pole, so we truely are looking outward in this image. Many of the galaxies in this image are ~50m million LY away, while some of the background galaxies are 90 million LY or more. Many of the galaxies in the PGC catalog don't even have listed distances, so I'm not even sure how far I am looking. I have captured Abell 347 before, and some of those galaxies are 300 million LY away, so I have no doubt many of the faintest background objects in this image could be a comparable distance.

Preliminary Processing:

- Lights for all exposures calibrated using Darks, Flats, superbias in PI, filtered with Subframe Selector, StarAlign-ed, and Drizzle Integrated

- Image cloned, run through ABE multiple times, and used for placement of DBE sample points (using ABE to reveal the darkest background amongst the nebula). DBE then applied to original image multiple times

- Luminence extracted

Luminance Processing:

- Deconvolution using Dynamic PSF as well as Star Mask

- John Rista Luminance NR using TGV, then MMT

- Masked Stretch using Image Statistics for "Target Background" value

- Ha only: used StarAlign to align narrowband images to color images

Color Processing:

- Background Neutralization

- Linear Fit after using Noise Evaluation, then Photometric Color Calibration using Avg Spiral Galaxy

- John Rista Chrominance NR using TGV, then MMT

- Masked Stretch using Image Statistics for "Target Background" value

Combined Processing:

- LRGB combination to re-introduce Luminance into color images

- HDRMultiscaleTransform to increase core detail on galaxies

- Saturation increase using Luminance masking

- PixInsight plate solving and annotation
