SH2-134 /SH2-135 in Cepheus in SHO (Summer 2022)

SH2-134 /SH2-135 in Cepheus in SHO (Summer 2022)SH2-134 is a massive emission nebula located in the southern part of the constellation Cepheus about 2900 light years from earth. It is roughly centered around the fifth magnitude, blue supergiant star λ Cephei.SH2-135 is a smaller HII emission nebula/region also located in southern Cepheus with a prominent and expanding ionization front. Current estimations of distance from earth are about 10,100 light years.Aside from SH2-134 & SH2-135, the field contains objects from Lynds' Catalogue of Bright Nebulae- LBN 485- LBN 486- LBN 488- LBN 489- LBN 490- LBN 491- LBN 492- LBN 492Also in the field is NGC 7281 & NGC7235 which are open clusters, respectively about 5300 and 9200 light years distant.

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.
