A crop of the last shot around the Prawn nebula IC4628

-------------

Thanks to SADR Team who welcome me onboard their Sadr association, and the 2 astrophoto setups in Chili. Southern Skies and its wonders just open to me !

My first Shot made with Sadr team in Chili with Fabien Trébuchet and Patrick Delay

After ten nights spaced out over two months, and hours of treatment, here is a first version.

Note also the pretty "blue-eyed fox" on the top right.

Mosaic of 4 tiles with TS 71mm 347 focal at 4.9

4 images of 25xLx300s + 30xRVBx120s + 50xHax300s

Fabien and Patrick => preprocessing,

Fabien => special thanks to him, who did all the mosaic assembling in drizzle mode : even with a powerfull PC, a pano x4 drizzle takes a lot of time , Fabien told us ;-)

The result is really fabulous : 4 frames at 16 millions pixels for each with x2 in Drizzle , it makes a final size of: 17193 x 13009 pixels, so it is around 223 millions pixels !

I share with you a REDUCED version at 5000x3788 pixels

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.
