New PN candidate, Lindstrom-Kagy-MarínOtero 1, was discovered during a collaborative project to obtain a deep image of Sh2-224.  This discovery was announced and briefly described in an addendum with our previously-published Sh2-224 image.

In this bi-color image of the new PN candidate, north is up.   The data are narrowband H-alpha and OIII with RGB stars.  The PN candidate shows a compact OIII shell (blue channel) with a more extended and diffuse H-alpha shell (red channel).  There are possibly multiple H-alpha shells.  A small star, visible in the center of the OIII shell, may or may not be related to the object but is compelling as a possible progenitor.  The PN candidate, at its shortest and longest dimensions, is 1' 9" wide and at least 2' 27" in length.  A second object to the lower right of the PN candidate is the galaxy, PGC 168881, which lies nearly in the same line of sight as the PN candidate.  The galaxy has a redshift of .040727, which gives it a derived distance of more than 500 million light years.

317 hours of data went into this final processed image.

• Data captured from September 2022 to January 2023
• 175 hours H-alpha
• 139 hours OIII
• 3 hours RGB

The data were collected across 3 imaging rigs.

• FSQ106 / ASI2600
• SVX140T / ASI6200
• AT80EDT / ASI1600 and ASI183

The PN candidate was discovered after collecting 200 hours of data with our rigs aimed at Sh2-224.  The new object was noticed at the very edge of this field of view.  After detecting the new object, an additional 100-plus hours were added with our scopes centered on the new object's coordinates.  In order to reveal these never-before-seen details, the sheer high number of integration hours that went into this object no doubt helped meet the challenge of imaging this faint, small object with modest amateur instruments.

Our data for the object were submitted to the French Planetary Nebula Hunter Team at planetarynebulae.net where the object was accepted as a PN candidate.  Their assistance was invaluable in also getting the object registered as a new PN candidate in the HASH planetary nebula database in January 2023.
