Hickson 44 / Arp 316

I started this one in March of 2019 but couldn't grab enough data since I have a tall tree directly to my east. I had to wait for it to clear that first (almost at the zenith), so I was generally only able to get 2 to 2.5 hours a night. I tried processing what I had last year, but the results were awful and I couldn't bring myself to publish it. I went after it again this year (with the replacement scope) and wasn't able to get the diffraction spikes to line up perfectly. I'm not sure whether that was due to photographer incompetence, manufacturing tolerances or time of year differences (by that I mean that I've noticed in the past that when I image something over a couple months, there is a slight rotation in the field even if I don't move my scope or camera). I thought about discarding last year's data to try to fix that, but the advantages of using all the data far outweighed the benefit of having sharper spikes.

Anyway: NGC 3187 has always reminded me of the Kataan Probe/Necklace from the Star Trek TNG episode "The Inner Light".

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.
