Venus on July 11, 2023

Acquisition type: Lucky imaging

Imaged Venus on the evening of July 10, 2023 (7/11 in UTC). Venus had a diameter of 39.2" and was 23.9% illuminated.

Imaged with a C8 Evo, Siebert 2x barlow, ZWO ADC, Astrodon Johnson/Cousins Photometric UV and Baader IR 685nm pass filters, and ZWO ASI174MM. Imaging train was configured to give me ~F/20 (FL=4000 mm). Image capture using Firecapture with the following gain/exposure settings: UV: g=400, 20ms; IR: g=250, 1.5 ms. Stacking in AutoStakkert3 (best 5% of 20000 frames captured over ~180 seconds for IR, best 10% of 10000 frames capture over ~360 seconds). De-rotated images in WinJupos. Generated false RGB in WinJupos (R=IR, no green, B=UV).

Original version: Compilation of IR, UV, and IR/UV images

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.
