Dear friends,

heavy workload kept me away from AB for quite some time.

However, at least I had managed to pull out my camera under the sky and take advantage of a clear night in November. Since the moon was shining brightly, using an Ha filter was mandatory.

On that occasion, I could try my new Redcat 51 for the first time (at least the many working hours payed off fortunately in this regard ;-)

Sh2-134 is a very large object in the constellation of Cepheus. It is a nice region around lambda Cephei (center) with lots of HII regions along with dark nebulae such as B 173-174 (L-shaped structure above zeta Cep) and B 169-171 (C-shaped structure to the right thereof). The region around lambda Cephei is designated Sharpless 134 and the smaller bright region to the left is Sharpless 135.

If you like to leave a comment, suggestion, critique or the like, feel free to do so. It is always appreciated.

Still all the best for 2021 and stay healthy!

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.
