First image of planetary nebula Si 1-2

Image Title: First image of planetary nebula Si 1-2

Date image was taken: August 02, 2023

Image Description and Details : This is believed to be the first image of ths target other than a faint presence on sky surveys.

It was discovered by Gisela Strigl in 1996.

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, and remarkably not even the HASH database has an IPHAS image of it.

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.

Images were captured from my remote robotic dual-rig setup in Spain.
