NGC6765

Acquisition type: Lucky imaging

This is a very odd planetary nebula. It appears to be mostly emitting green OIII light. Some say its small, but its actually about 80 arc second across, so not dissimilar in size to M57. There aren't many images of it out there. Its all one color, with a very bright saturated central bar structure that is difficult to color correct.

The moon was nearly full, so I experimented with capturing this using a UHC filter that passes OII and H-beta lines along with the red H-alpha line and longer wavelengths up to near-IR. The filter worked reasonably well. The star colors were not well captured with this filter, so I mostly let the stars go to white.

Each of the 8 eight minute images were composed of 320 1.5 second exposures live-stacked in SharpCap.

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.
