Venus on June 16, 2023

Acquisition type: Lucky imaging

Imaged Venus on the evening of June 15, 2023 (6/16 in UTC). Venus had a diameter of 27.1" and was 42.8% illuminated. Seeing was very good, but transparancy was terrible due to wildfire smoke (my UV images required 7x the typical exposure time to get the same histogram levels). Turns out the fine seeing was all that matter as these are some of the more detailed UV images I've managed to obtain.

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=375, 75ms; IR: g=250, 3 ms . Stacking in AutoStakkert3 (best 5% of 20000 frames captured over ~180 seconds for IR, best 15% of 5000 frames capture over ~360 seconds). De-rotated images in WinJupos. Generated false RGB in WinJupos (R=IR, no green, B=UV).

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.
