The Cave (Sh2-155, C9)

In the constellation Cepheus, 2400 light years from Earth, is the Cave Nebula. It is a complex region with a collection of emission, reflection, and dark nebulosity. The crescent-shaped cave is rich in Ha and is a region of active star formation. Also in this image is the VdB155, a soft-blue reflection nebula.

This was my most integration-intense project. Over a five-week period I collected more than 50 hours of data, and used just over 38 hours for this image. About half of the data were collected with a WO GT71 (FL 336) and the other half with a WO FLT 132 (FL 925). For the GT71 data, only subs with an HFR ranging 1.5-1.9 were used, and for the FLT132, subs ranging from 2.3-2.9 were used. In the processing of this image, I used the wide angle data for the color mapping and the narrow angle data in the creation of a master luminance mask. This image uses SHO with standard Hubble color assignments and star color provided by RGB data.

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.
