SH2-155 Cave Nebula (OSC from Bortle 6)

SH2-155 is called the cave nebula, probably because of its appearance as a gaping cave mouth. I really like this wide field with numerous further objects in it. This is one of my first pictures with the RASA 11, and it's also the best so far - I've not really come to grips with that telescope, which has been largely superseded by my Epsilon - which produces a sharper image, holds collimation longer, is easier to collimate and works well with narrowband filters - at a price of about 2x increased integration time. The overwork of this image was long overdue, It has lost a bit of definition of the reflection nebulae, but reveals more detail in the hydrogen parts.

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.
