NGC1491 - Fossil Footprint

An interesting target to capture in narrowband, this can be a tricky target to process due to the close overlapping layers of gas. Fantastic to view the outer edges of emission nebula plus a nearby star cluster in frame.

Acquisition:
3nm SHO, OSC for RGB stars. I was able to get decent data even with a bright moon on this one since the glow wasn't too close. However, I did throw out half a night's data for a much better background gradient and sharper details. I will experiment some more with less acquisition time but less atmosphere with a higher target in the sky. Even with weighting algorithms that should reduce the impact of low horizon shooting, I found it rather remarkable how much better 1 hour before and after the meridian flip the data looked. Veteran astrophotographers already knew this of course, but it is worth experimenting if you haven't already.

Processing:
Kind of a pain to reshoot a target just to get RGB stars for a NB target, but it is growing on me. 60s during the full moon still worked for the stars. There's a lot of red emission gas on this target so I had to guess how far to push it. Red is all brown to me so I hope 'brighter' brown looks redder to everone else. Striking blue in the core really highlights the rest of the palette literally. Went back and forth on reducing it a bit, but I ended with brighter since the rest of the image is more of an even level of brightness.

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.
