Das Bild ist mit zwei Fernrohren gleichzeitig aufgenommen worden.

Der Hypergarph mit der ZWO Asi 178mm für Luminanzbilder und der Newton für die RGB Bilder mit der ZWO Asi 178mc.

Beide Kameras sind üngekühlt.

Ich versuche mit kurzen Belichtungszeiten im Luminazkanal der Luftunruhe entgegen zu wirken.

Die Luminanz wurde mit 5 sec. belichtet, die RGB Bilder mit 20sec. am Newton.

248x5sec. Luminaz und 61x20 sec. RGB.

Verarbeitung in Fitswork und PixInsight.

Unter dem Link sind noch weitere Bilder aus der Nacht mit der gleichen Technik zu finden.

The picture was taken with two telescopes at the same time.

The Hypergarph with the ZWO Asi 178mm for luminance images and the Newton for the RGB images with the ZWO Asi 178mc.

Both cameras are uncooled.

I try to counteract with short exposure times in Luminazkanal the seeing.

The luminance was exposed for 5 sec., The RGB images were exposed for 20 sec. at Newton.

248x5sec. Luminaz and 61x20 sec. RGB.

Processing in Fitswork and PixInsight.

Under the link you can find more pictures from the night with the same technique.

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.
