Hi Starfriends,

Many thanks to the team at RoboScopes !!!

This is the most comprehensive dataset I have been able to download from a remote observatory. The data were not yet calibrated. In addition to Ha, OIII and RGB (red, green and blue), this time there were also bias, flats and darks. The data could be edited by me from scratch. The OIII area was strong.

NGC 6960 is part of the western part of a collection of emission and reflection nebulae located about 2400 light-years away in the constellation Cygnus. Together they are the remnants of a supernova that took place around 8,000 years ago.
The nebula was discovered by Wilhelm Herschel on September 5, 1784. He described it as: “Extended; passes thro' 52 Cygni... near 2 degree in length"; the eastern part as "Branching nebulosity... The following part divides into several streams uniting again towards the south."

Thank you for watching and stay healthy
I hope you like my edit?

Hi Sterfreundinnen und -freunde,

Vielen Dank an das Team von RoboScopes !!!

Das ist das bisher umfangreichste Dataset, was ich von einer RemoteSternwarte runterladen konnte. Die Daten waren noch nicht kalibriert. Neben Ha, OIII und RGB (Rot, Grün und Blau) waren dieses mal auch Bias, Flats und Darks dabei. Die Daten konnten von Grund aus von mir bearbeitet werden. Stark war dabei der OIII-Bereich.

NGC 6960 gehört zum westlichen Teil einer Ansammlung von Emissions- und Reflexionsnebeln, die sich in einer Entfernung von rund 2400 Lichtjahren im Sternbild Schwan befinden. Sie sind zusammen der Überrest einer Supernova, die vor ca. 8.000 Jahren stattfand.
Der Nebel wurde am 5. September 1784 von Wilhelm Herschel entdeckt. Er beschrieb ihn als: „Extended; passes thro' 52 Cygni... near 2 degree in length“; den östlichen Teil als „Branching nebulosity... The following part divides into several streams uniting again towards the south.“

Vielen Dank für's Anschauen und bleibt gesund
Ich hoffe, meine Bearbeitung gefällt etwas?

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.
