A bright beacon in Corvus - NGC 4361

Link: http://www.starscapeimaging.com/NGC%204361/NGC4361.html

NGC 4361 is a planetary nebula in the southern constellation Corvus which shines at estimates of magnitude 10.4-10.9 and is thought to be around 4 thousand light years distant. The central star, which has shed much of its gas was once thought to be a sun like star. This planetary nebula is a bit unique among low mass star planetary nebula as it has a bi-polar jet which are typically not observed from low mass stars. It also is very filamentary in nature.

The image above was taken through Red, Green and Blue filters along with a 5nm wide HII and OIII filter. The red in the central part is from hydrogen emission and the blue/green color from an abundance of OIII emission. NGC 4361 also goes by the designations: ARO26, PK 294+43.1, and PN G294.1+43.6

The image combines 11hrs and 35min of data. The image above is a cropped field of view. To see the full res image see the web link. The image was taken using 1x1 binning at a resolution of .64 arcsec/pixel but using a 1/2 frame region of interest. Processing was done in PixInsight with a few final tweaks in Photoshop.

I started quite late in the season on this image and ran out time before it got too low in the southern sky. However it's bright enough to show its full glory even with a fairly short exposure time. Imaged from 21 April - 31 May 2021

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.
