This is a 2 x 1 mosaic acquired over two nights (scale reduced to 50% of original).

This is my first (successful) mosaic.

It was assembled in PI using Gradient Merge process. The overlap region is the vertical strip in the middle of the image. I had to use the geometric correction to build the mosaic, because the image is covering a large field.

The FWHM is 7 arcsec, I found it difficult to go below 6 arcsec with the hyperstar on my C8 ... I dont think this is very good.

Pre-processing done in Pixinsight :

- overscan area offset correction

- bias correction

- flat correction

- hot pixel correction

- debayer

- registration

- stack

Processing done in Pixinsight :

- backgroung color neutralisation

- color calibration using nebula

- gradient merge mosaic

- residual sky background substraction

- color saturation boost

- green neutral

- non linear image creation

- erosion

Final image :

- jpeg calibration done in Mac Photo scaled at 50%

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.
