LBN 437

This is my first attempt at a "dark" nebula. LBN 437, The Gecko Nebula, lies fittingly in the constellation Lacerta, the Lizard.

The Gecko Nebula is paired with the large emission nebula Sh2-126 that runs through this frame. The left lobe of the Gecko contains many bright stars that were newly formed from the cloud. In this region, the young star V375 is associated with the X-shaped Herbig-Haro object HH398.

I struggled to get the proper length of sub exposure to not blow out star and to pick up as much of the dust as possible. Settling on 120 sec subs from bortle 5 seemed to work the best. The Ha signal from SH2-126 is very bright and easily visible in the red channel alone, but collecting Ha data really made it jump out. There are a lot of elements in this image, narrowband, RGB, and faint dust that required special and seperate processing to bring out in full detail. I completely changed my workflow for this type of target, and Im happy with the result. This opens up so many more target options with these type of nebula being widespread all year around.

As a side note I had to show what the Eq6-R ( 2.5 years old) can do in the right conditions. Seeing was great and the 37lb payload was guiding incredible, 0.4-.5 all night long screen shot attached as revision!

Thank for looking!

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.
