NGC 1491/LBN 705

I am nothing if not a glutton for punishment. I repeatedly choose to image dim emission nebulae with my stock, unmodified Nikon D5300, despite the fact that I know that by doing so, I am fating myself to a long, arduous slog of processing, with no guarantee that the final product will be anything other than a mediocre image. I subjected myself to this tom-foolery once again earlier this week, having picked as a target NGC 1491, a rather dim emission nebula in the constellation Perseus.

NGC 1491 is, in fact, the brightest portion of the larger emission nebula LBN 705. The main source of the nebula's illumination is the moderately bright star located in the "hollow" interior of NGC 1491. The radiation from this star is eroding the surrounding gas, creating NGC 1491's distinctive arrow-like structure. LBN 705 is located about 10,000 light years from Earth.

Two other interesting objects are included within the field of view of this image. At the upper right is open cluster King 7, which also has an arrow-like shape. Located closer to us than LBN 705, King 7 lies somewhere between 5, 500 and 8,500 light years away.

A bit below and to the left of King 7 in the image is reflection nebula GM 1-34. This object is listed in the Gyulbudaghian+Maghakian catalog of reflection nebula containing Herbig-Haro flows.

A final word--the madness may soon be ending. As a 70th birthday present to myself, I will likely be sending my camera off to be modded this spring. That is, unless a sudden wave of masochism overwhelms me between now and then.

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.
