Mars on August 25, 2018

Imaged Mars and Saturn on the evening of August 25, 2018. Seeing was average to good (CDS forcast of 3/5), but not nearly as good as the previous night. The images are correspondingly less impressive. Seeing truly is king...

Imaged with a C8 Evo, custom Siebert 2x barlow, ZWO ADC, Baader Moon & Skyglow filter, and ZWO ASI224MC. Imaging train was configured to give me ~F/25. Image capture using Firecapture with gain set at 320 and exposure at 2.5 ms. Stacking in AutoStakkert3 (best 10% of ~45,000 frames captured over 300 seconds). Color balancing and Wavelet sharpening in Registax6.

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.
