Mars 21 Mar 2024 - 5 Minute Stack

Acquisition type: Lucky imaging

Red Planet half an hour after sunrise on Fri 22 Mar 2024.

Bit of an experiment here with AutoStakkert's 1.5x drizzle option (pair of images in bottom row). I wanted to see whether additional detail can be pulled from an already oversampled view. Suffice to say that the results are encouraging, especially around the ice cap which shows additional structure.. a rift perhaps? Seeing kept improving as the morning progressed, peaking around 7:30 am Canberra time. Dawn sky was already very bright lowering contrast of Martian albedo features. Resolution of the native F17 image is 0.055" or 90 km per pixel, 0.037" or 60 km for the drizzle version.

This capture is centered on longitude 265 with Mare Tyrrhenum and Syrtis Minor crossing the terminator. Syrtis Major is rising in the west, Hellas Basin immediately to its south. Dark markings of Zea Lacus are detectable in the middle of the Basin. Pencil of Tritonis Sinus (at the western edge of Mare Cimmerium) is setting in the east. Mars will continue to get higher in the morning sky unitil early June for us in the south. Unfortunately it's not going to grow much in that time, staying under 5.2" in diameter.

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.
