LDN 1622 & vdb 62 - 2018

This object is a cometary cloud located "only" 500 light-years away in the constellation of Orion. It spans about 10 light years across. The densest parts of this cloud completely block out the background stars.

The most interesting aspect of this object to me is the bright yellow young pre-main sequence star (HBC 515) seen on the right side of the image. This star is one of the visually brightest young stars known. The star is surrounded by a yellow reﬂection nebula designated as vdB 62 or Parsamian 3. I also find it interesting that the cloud is silhouetted against a faint background of glowing reddish hydrogen gas.

This cloud has been identified as the birthplace of many other stars besides HBC 515. Typical of such a cloud, a number of Herbig-Haro objects and outflows have been identified in this region but I could not positively identify any of these very faint objects in my image.

This is the toughest object I have processed to date. Nothing showed up in my RGB or Ha subs, and the Lum subs only faintly suggested that anything was there besides empty space. Despite that initial discouragement, I am happy with the final result. Modern processing is a wonderful thing! Hopefully in the coming years I can add to the integration time and more fully capture this amazing object.

The refractors!

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.
