Si 1-2 is an enigmatic planetary nebula that has, to my knowledge, never been imaged before.
It is relatively small at 60 arc seconds, and reasonably bright as this was captured by moonlight.
A Google search turns up no information about it, although it can be detected in the Panstarrs and DSS surveys.
Spectroscopy wasn't performed until 15/05/2016 by the OSIRIS instrument.
Osiris is the Optical System for Imaging and low-Intermediate-Resolution Integrated Spectroscopy at the world's largest single-aperture optical telescope (the Gran Telescopio Canarias - a 10.4 m reflecting telescope located at the Roque de los Muchachos Observatory on the island of La Palma, in the Canaries, Spain).
This confirmed that Si 1-2 is a true planetary nebula.
My thanks to Sakib Rasool for suggesting this target.

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.
