13th Magnitude Comet 103P/ Hartley Ghosts Mirach and the Ghost of Mirach (NGC 404) 2023-08-15. Tight on the framing since I wanted to make sure that a potential cometary tail would fit in the frame over the 80 minute exposure time. That placed 2nd magnitude Beta Andromedae (Mirach) on the edge of the field for poor framing. To permit an easier view of the elliptical galaxy, NGC404 (Mirach's Ghost), to shine through, Mirach's halo I had to severely limit that halo's brightness. I then cheated by darkening the entire background, eliminating any chance of seeing the typical IFN within the FOV. I'm not fond of the results but will leave it as is since I have more comet images to process.

Comet 103P/ Hartley continues to brighten and close in on both the Earth and sun's perihelion (predicted to be at the comet's brightest) in early October. We'll see...

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.
