NGC 5866 | So Perfectly Edge-On

NGC 5866 features a sharply defined dark lane that indicates a precisely edge on alignment. The galaxy may be lenticular or spiral - it's hard to say from this angle. The dark lane is not visible with a traditional stretch, but PI's HDRMT or a tool like that will reveal it. I wasn't happy with my HDRMT result (even though this is Adam Block's tutorial object for HDRMT...) so I used two separate stretches in CCDStack and blended them in PS.

Once the dark lane is revealed, the contrast lends a sense of sharpness. The tips of the lane seem to brighten to a cyan/blue due to the typical young stars in the outer areas of the galaxy.

Outside of the very bright center the galaxy is quite dim and if you squint just right appears to have a globe like halo. Stretching enough to see these dim bits really amplified the noise which was difficult to control. At some point you just have to be done...so here it is.

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.
