Mars on September 5, 2018

Imaged Mars on the evening of September 5, 2018 (UTC) under some of the best seeing conditions I've experienced this Mars apparition (CDS forcast was for excellent seeing with average transparency). Thanks to the steady seeing I was able to collimate my C8 prior to imaging (with the at best good seeing earlier this summer, my collimation was a bit off and my images suffered for it). I imaged using both a Baader UV-IR cut filter and the Celestron Mars filter. The Celestron Mars filter resulted in nicely high contrast images. The color balance is pretty funky (much like an IR pass filter), so I converted the Mars filter images to black and white. I then de-rotated and combined RGB and BW Mars filter images in WinJUPOS (7 RGB images, 4 Mars filter images). The end result was an RGB image with improved detail.

Imaged with a C8 Evo, custom Siebert 2x barlow, ZWO ADC, Baader UV-IR cut filter/Celestron Mars filter, and ZWO ASI224MC. Imaging train was configured to give me ~F/25. Image capture using Firecapture with gain set at 275 and exposure at 5 ms. Stacking in AutoStakkert3 (best 20% of ~50,000 frames captured over 300 seconds.). Color balancing and Wavelet sharpening in Registax6. Derotated and combined five images in WinJUPOS.

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.
