Flamingstar Tadpole 3 panel mosaic

Using the TMB 80 I composed a 3-panel mosaic to try and capture a large area of interesting objects. My skies are fairly bright so decided to go with RGBL and Ha. For each of the 3 panels 21x180sec for R,G&B filters and 53x300sec for Ha. Data was processed to masters for each filter/panel in Pixinsight and then the 3 frames for each filter were integrated into a mosaic using AstroPhotoProcessor. Back in PI the RGB combine and all remaining processing was done.

A key step was using starnet process in PI so I could treat the nebula and stars separately for final stretching. After the big data loss I reprocessed differently.. Blended Ha into red and tiny bit into blue of the RGB. Removed stars.. acdnr then removed stars and made RGBH_L with L being the starless Ha. Also made stars-only from the RGBHa and Ha and made similar RGBHA_L for those and recombined in PSD by simple paste of stars onto the RGBHa_L in screen mode.

Description: Sort of caught by the data loss. event. all images dumped.. Reprocessed but wanted try and share again because the processing workflow was rather different..

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.
