Tarantula Nebula NGC2072

The Tarantula Nebula is a very luminous emission nebula located in the Large Magellanic Cloud. It is located in a rich field of dust and Ha emitting gas within galactic starfields. I think this accounts for the background colours that were difficult to remove without loss of detail in the vicinity of the main target. This is a narrowband image with total integration time of around 16 hours, taken from an apartment balcony in a small town in New Zealand with clear dark skies. (Even darker as tourists had left the town in the coronavirus lockdown for two of the three nights of imaging)

Ha 65x5 min

OIII 66x5 min

SII 63x5 min

Linear processing in Pixinsight:

Weighted Batch Preprocessing

Mure Denoise

Dynamic Background Extraction

Deconvolution with starmask, background mask and PSF calculated using PI Script

RGB Combination using Hubble (SHO) palette

Background Neutralization with aggregated previews

SCNR to remove 90% of green

HDRMultiscale Transform to sharpen core of image

Non-Linear Processing:

Masked Stretch

Curves Transformation

Histogram Transformation to shift blue channel

Curves Transformation

TGV Denoise mainly for chrominance channel

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
