Mars before dawn on Sat 25 Apr 2020 AEST.

My first Mars derotation this apparition. The planet sports a modest 7 arc second disk now and it is becoming easier to discern surface markings on live capture feed. This view combines 18,000 best frames recorded over half hour between 5:28 and 5:57 am Canberra time.

As it turns out I was imaging around the same time as my fellow planetary photographers around the country - Andy Casely in Sydney, Niall MacNeill in regional New South Wales and Anthony Wesley in Queensland. It is interesting to compare this aspect of the planet from our respective vantage points. Chevron like structure covers the southern portion of Syrtis Major and there's quite a lot of dust in the Hellas basin. Tongue of Sinus Sabaeus is rising in the west. SPC appears very bright and is fringed by a magenta boundary detected by Niall in his image.

I was pleased to capture subtle colour differentiation with the OSC, seeing was very good before arrival of fog at sunrise.

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.
