Howell-Crisp 1 (HoCr1) in IC444

When processing my recent image of the Jellyfish and IC444, I noticed a small PN-like object in IC444. Loking for it in Aladin Sky Atlas I found that it was HoCr 1, a quite small (73") planetary nebula also known as Howell-Crisp 1. It was discovered relatively recently (2006) by amateur astronomers Michael Howell and Richard Crisp, see: www.horizontalheavens.com/planetarynebulaproject.htm. I have here made a drastic crop and further processed the image to make the PN stand out a bit better, and I am slightly impressed by the RASA8 to pick up this small thing under a full moon. There are of course some more detailed images of it using longer focal length scopes, like this nice one by @Peter Goodhew : https://www.astrobin.com/pn6nlr/

In my Jellyfish nebula image you see this PN near the upper edge of the image just a bit left of the centre (looks like a red star): https://www.astrobin.com/b45uot/

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.
