NGC6946 Widefield

While imaging NGC6946 with Moravian CCD on the 10", my Eoa 600da and the 200L lens were mounted on Vixen Polarie, to get a widefield impression of the area. Next to the galaxy, the open star cluster NGC6939 is the second prominent deepsky object on the photo. There are some dark nebulae in the field, the one on top is called B150. The 200L is not bad, but far from the performance of the 100L, the red channel is not quite sharp and astigmatic aberrations plague the edges. So only a 66% view is presented. North is left in this picture. Note little UGC11557, a 13mag galaxy, from 6939 down in a right angle to 6946, and roughly double the distance.

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.
