Sh2-290 (Abell31) in Hα/OIII/OIII+rgb

Dim Planetary Nebula at Cancer, really dim.

With a surface magnitude of 27 arc-sec-1, it was discovered in 1955 by George Abell.

It is estimated to be about 2,000 light years away.

This picture is the result of my longest integration time up to today, it's more than 90 hours of frame capture during the past 3 years.

The work desk was complicated due the different scopes and cameras used and the low signal captured.

Description: Just for documentation and see how dim it is.
This the best Ha frame of this nebula with 600s that I captured (fully calibrated).

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.
