Exoplanet WASP-11 b Transit (2024_01_29) (Dan Price)

Exoplanet WASP-11 b Transit (2024_01_29)

Exoplanet Transit - WASP-11 b.

Star - WASP-11, V or Gaia mag 11.6. Approximately 424 light-years (130 pc).

Telescope - Celestron EdgeHD 11"
Camera - ASI6200mm Pro
Mount - Astro-Physics Mach2GTO (guided)

Transit Finder - https://astro.swarthmore.edu/transits/

Data collected Jan 29, 2024. 102x120s Luminance images. Duration of transit - 154 minutes.

From NASA - "WASP-11 b is a gas giant exoplanet that orbits a K-type star. Its mass is 0.79 Jupiters, it takes 3.7 days to complete one orbit of its star, and is 0.0435 AU from its star. Its discovery was announced in 2008."

Note - I previously posted WASP-11 b using data collected on October 28, 2023. I decided to repeat the procedure in order to check if my results were repeatable. The major difference is that for October 28, 2023 the ASI6200mm Pro gain was set to 0, and for January 29, 2024 the ASI6200mm Pro gain was set to 100. With gain 0 the max ADU was roughly 16000, while with gain 100 the max ADU was roughly 55000!. Of course, the seeing conditions and temperatures may also have contributed.

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.
