LBN437 / SH2-126 - The Gecko

LBN437 is a molecular cloud complex in the constellation Lacerta colloquially known as the Gecko Nebula. It is located on the edge of the large Ha emission known as SH2-126 which is the source of the red bands that pass through the image.

An interesting and prominent feature of LBN437 is a symmetrical reflection nebula associated with the Herbig Ae/Be star V375 Lacertae. This star is also host to a bipolar jet and professional observations have detected multiple small Herbig Haro objects. It is visble as an hourglass or X shaped reflection in the top right region of the moloecular cloud.

Processing was a challenge due to the blending of the Ha signal into the red channel. It is a fine balance trying to find the right level of continuum subtraction that results in an accurate representation of the Ha signal relative the to natural red signal.

Thanks for checking it out.

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.
