When the moon sets early, it's time for broadband imaging again. Now that you can see a little more to the north from the new balcony, NGC 7789 seemed the right choice. In addition, no meridian flip was necessary until dawn during the relatively short summer night, although I haven't had any problems with NINA doing meridian flips for a long time. I am surprised that it was possible to work out some dust in the background. At least I hope it's dust and not some other weird gradients.
And: I did not expect to be a quite clear night until 3am, as the morning before was still rainy and wet. Unfortunately, it resulted in a little bit more dew on the scope and from 1am on high clouds started to appear, which resulted in error messages in PHD2, nevertheless guiding in combination with NINA continued. So I simply put all 83 images right into the stacking process. ;-)

From Wikipedia
NGC 7789 (also known as Caroline's Rose, Caroline's Haystack, or the White Rose Cluster) is an open cluster in Cassiopeia that was discovered by Caroline Herschel in 1783. Her brother William Herschel included it in his catalog as H VI.30. This cluster is also known as the "White Rose" Cluster or "Caroline's Rose" Cluster because when seen visually, the loops of stars and dark lanes look like the swirling pattern of rose petals as seen from above.

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.
