Last year, I made my initial attempt to capture this particular target, but unfortunately, I couldn't successfully extract the Oiii data from it. However, I was given another opportunity with improved equipment and enhanced processing skills compared to the previous year. I dedicated approximately 34 hours and 50 minutes to this endeavor. It may seem like a significant amount of time for this dataset, but I had to begin observing the target early due to its position at around 10 degrees, and it would disappear from my view at approximately 60-65 degrees. Consequently, the telescope didn't have sufficient time to gather a satisfactory signal-to-noise ratio (SNR) from my location, primarily due to the interference of bright city lights, which even affected the visibility of the 3nm Oiii wavelength. Despite these challenges, this is my most successful attempt so far. I will now be shifting my focus to another region of the sky.

Until then clear skies.

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.
