Venus Blue-Violet-UV as RGB with mouse over for the visible light image

Acquisition type: Lucky imaging

On the same evening as I captured Venus in IR and UV, I was also pleased to see the considerable detail coming across in the Blue-Violet part of the spectrum. This false colour image is then "spectrum shifted" to the shorter wavelength end of the spectrum with Blue mapped to Red, Violet to Green and UV to Blue. This false colour approach is less contrived than the IR_UV false colour convention, in that it just moves a part of the spectrum (Blue, Violet, Ultraviolet) across to the visible spectrum.

I use a Luminance filter in line with the Wratten #47 Violet filter to block the IR leakage. It would be better to use an IR block filter in series as I am probably losing some of the shorter wavelength end of the Violet filter. Any recommendations most welcome.

It is interesting that the Violet image is more like the Blue image than the UV one, whereas in the past I have seen the Violet and UV images being more similar. I don't know why.

The mouse over shows a contrast enhanced visible light image, where subtle banding can be seen.

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.
