Sh2-155 or 'The Cave' is an emission, reflection and dust nebula located in Cepheus.
it is the tunnel or the path to the other side, LOL.

image taken with the 235 mm SCT F/6 scope with Baader cmos-optimized SHO,
This is a new project and more data will be captured if weather allows.

Data stacked with ASTAP, using standard options, 30 flats of 3 sec @ 15k mean ADU, 30 flat darks at 3s, 30 darks at 6 min.

3 hrs of data at exposure of 360 sec. On October 19/20, acquired additional 3 hrs of O-III during full moon. Imaging with the O-III filter during full moon is not optimal, but I have to use what the universe provide.

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.
