T Coronae Borealis prae announced nova event 2024

I would like to try to photographically document the nova of the cataclysmically variable binary star T CrB, which is announced for 2024.
T Coronae Borealis is the reddish star in the center of the image, it is classified as a red giant and has a white dwarf companion that orbits it very closely. And so close (0.54 AU) that the white dwarf can continuously withdraw hydrogen from the red giant. About every 80 years the dwarf reaches a critical mass, causing a nova explosion. Due to the typical brightness fluctuations just before exploding, this recurring event has been forecast for 2024, by September at the latest, during which the star will shine very brightly for a few days.
I hope I'm lucky enough to capture this event, the picture shown is close before going nova.

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.
