Barnard 174 Dark Nebula in Cepheus Ha+OSC RASA 8

This nebula is a quite striking dark nebula in the constellation of Cepheus. It's an active star formation area with surrounding cold gas at -263 degrees Celsius ideal for gas to condense under gravity with out being too energetic to form new stars.

I tried to emphasize the star background here along with the nebula on my initial OSC image (https://www.astrobin.com/8k1aub/), now with this image focusing on the fainter hydrogen gas.

As usual, the RASA 8 preforms well an the full page and full resolution show the detail the astrograph is capable of producing. Also, if you check out the corners, it shows how flat an image the RASA 8 can produce when using a EAF. The scope takes a lot of heat for not having a flat image place, but I have found that is mainly due to the very narrow critical focus zone that I cold never get by hand with the focuser until I switched the to the ZWO EAF.

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.
