Winter is leaving

Hi,

As the winter sky is slowly leaving, I present you my mosaic of the winter nebulae.

It was a very tough work, especially for matching all the panels because of the different sky quality (most of the time high clouds this winter).

So, 12 panels, with variable integration time, from 80 to 240 x 30 sec per panel.

Pictures taken in January and February.

Matching is not perfect, but I'm quite satisfied wth the result considering the sky quality.

It needs one more panel to avoid the lower Sirius reflection ;-)

The original mosaic is almost 85 mpx. This picture is reduced at 70% with 70% jpeg compression. It may take some time to be completely loaded.

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.
