Small Magellanic Cloud - 9 Panel Mosaic

Link: https://flic.kr/p/2iwWG7d

This version of my project on the Small Magellanic cloud adds another three rows for a 9 panel mosaic. Each panel is comprised of data captured through four filters, Ha, R, G & B. RGB subs are 5 minutes each and the Ha is 20 minutes per sub. The target for image acquisition was to capture at least 30 good subs for each of the RGB filters and at least 20 subs for the Ha.

For the nine panels included in this image, there are a total of 962 subs for an integration time of over 125 hours (not counting the bad subs that have been thrown in the bit bucket!). The file sizes for the 962 subs add up to 16.1 Giga Bytes of data. The field of view for each frame is approximately 1.5 degrees by 1.0 degree with a 20% overlap allowed between each frame during data capture.

Data acquisition software is SGP Pro and processing has been completed entirely using Pixinsight 1.8.8-4. Mosaic construction in PI made use of the Mosaic by Coordinates and Gradient Merge Mosaic tools. To post the image on Astrobin the resolution was reduced by 50% prior to saving as a JPEG. When saved as a TIFF file from Pixinsight, it results in a file size of 293 Mega Bytes.

The image is also available on my Flickr site by clicking on the link above.

Clear skies,

Rodney.

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.
