Polar Perseids, 12-13 Aug 2015

A few more meteor trails. The background is a Deep Sky Stacker stack of 141 36-sec images (with a 4-sec delay between images) taken with a Canon PowerShot A560 on a fixed tripod. The camera has nasty amp glow, visible in the upper left corner even though I used matched darks to try and eliminate it. I did not use flats (obviously). I then examined each aligned, stretched image looking for meteor trails. The few I found I layered on top of the background, applied a hide all layer mask, disabled the mask and cut it to show the meteor trail, Gaussian blurred the mask, and adjusted levels in each meteor layer to try and match the background. In this image, Perseus is at the upper right, and the brightest star, above and left of center, is Polaris. Some of these trails do not appear to be Perseids because they are not coming out of the Perseid radiant. I had a couple of other trails that I think must have been high satellites (high enough to be out of Earth’s shadow at this hour, around 3 AM); I did not include them.

The revision has more stretching in the background and more subtle blending of the meteor trails.

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.
