Spiral Perseid Meteors, Heart and Soul Nebulae, Star Clusters and Comet 21P Giacobini-Zinner

The annual Perseid Shower put on an unusual show in August 2018 with comet 21P/Giacobini-Zinner

nearby. Following detection of a spiral meteor through the Heart Nebula during the 2016 Perseid meteor shower, I elected to run several cameras with longer focal lengths than is usually done by meteor photographers. In the image, meteors are green, hydrogen emission nebulae are red, the star clusters are varied in color from bluish (hot young clusters) to yellow and orange (older cool stars). Comet 21P/Giacobini-Zinner is at upper left, showing a blue-green head from carbon emission, with a brownish dusty tail. Interstellar dust is burnt-orange and shows throughout the scene in this natural color image. The idea for using longer focal length lenses was to get some statistics on how many meteors rotate as they enter the atmosphere. The answer is that every meteor I captured with 100+ mm focal lengths show apparent rotation. Other comparable images that I have seen online also show apparent rotation. Thus rotation is common.

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.
