PK164+31.1 (Jones-Emberson 1) (Bruce Donzanti)

PK164+31.1 (Jones-Emberson 1)

Another faint object that I have been wanting to try for some time. Jones-Emberson 1 (PK 164+31.1), also known as the Headphone Nebula, is a 14th magnitude planetary nebula in the constellation Lynx at a distance of 1600 light years. It is a relatively larger planetary with low surface brightness.

Given the faintness of this object and noting the mega-hours and/or dark sites others have used to capture this DSO, I was thinking about ways to enhance my chances of getting a decent image. I chatted with Christoph Lichtblau who recently posted a beautiful image (in fact, IOTD on 2 March) of it. I noted he uses the same camera and scope as me, but he uses a gain of 300 for the ASI6200mm vs. the 100 gain I use, as do most others. So, I decided to give it a try; however, I already had some data at a gain of 100. Not wanting to toss aside any good data, I decided to combine all of the data I had. Even given that, I can still see I really need more hours to get an image I am totally pleased with as I only captured part of the outer Ha shell. I think almost doubling my integration time and perhaps trying some 600s subs might really help this object pop out for me. Since we have some bad weather for the foreseeable future, I decided to just post what I have as overall, I am happy with the end result.

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.
