Breaking news! James Webb Telescope shows us the first image capture after full alignment

Above you can see the resulting image captured by James Webb Space Telescope after alignment process and looks better than the first, no?This shows the progress Webb has made in aligning its mirrors, configuring systems and components, and so on. We also expect even clearer images in the future.
"While the purpose of this image was to focus on the bright star at the centre (called 2MASS J17554042+6551277) for alignment evaluation, Webb's optics and NIRCam are so sensitive that galaxies and stars in the background also show up. This image uses a red filter to optimise visual contrast." said NASA.
More details will coming.
Below you can see the first image from James Webb Space Telescope!
In short about Webb's path to L2:
Webb was launched a month ago on December 25, 2021 in Kouru, French Guiana on the Ariane 5 rocket. 33 minutes after its launch, Webb opened its Solar Array, being the first Webb component to unravel from its original state. This was followed by a Mid Course Correction Burn 1a, named by NASA and MCC1a, being the first burn correction to put Webb in the correct orbit. Just one day after its launch, an antenna, the Gimbaled Antenna Assembly, was opened.
Two days after the launch and just one day after the first burn correction, Webb did the second burn correction, which is Mid Course Correction Burn 1b (MCC1b). After Webb was put in the right direction, it widened, unfolding the Forward Sunshield Pallet. And on the same day, Webb opened his Aft Sunshield Pallet.
After the first 4 days since its launch in French Guiana, the telescope made a new opening, more precisely it deployed its Deployable Tower Assembly (DTA). After 5 days of launch, it has unveiled a small and a medium element, Aft Momentum Flap and Sunshield Covers. On the 6th day, Webb started to be as we know it.
He untied two important symmetrical parts: Sunshield PORT Mid-Boom and Sunshield Layer Tensioning Ongoing
It's been 11 days since the launch, with Webb already in 2022. On the 11th day after its launch, it started deploying its Secondary Mirror and finished the process after a few hours. The next day, another important element was unveiled, Aft Deployed Instrument Radiator, this instrument is very sensitive.
13 days after its launch, Webb began unpacking Port Primary Mirror Wing, ending the process after a long day. Two weeks after its launch, it began to deploy another part of it symmetrical to the one opened the day before, meaning that after two weeks it opened its Starboard Primary Mirror Wing. Also two weeks after its launch, Webb is completely DEPLOYED!
On January 12, 2022, just 4 days after it was fully deployed, Webb had to straighten his mirrors. Thus began a process of moving two individual mirrors, also called Individual Mirror Segment Movements, which ended in two hours. Between the 18th and the 28th after the launch, Webb started to lift all 19 mirrors, except for two of them that started to be built later. "Mirror Segment Deployments COMPLETED" announced NASA on the 28th day of Webb's launch. On the 30th day, Webb makes his last burn correction before reaching L2, which is L2 Insertion Burn.
And now WEBB IS ORBITING L2!
We expect a lot more pictures from Webb after this. And of course more data from our big, beautiful Universe. Good luck Webb! We are waiting for the most beautiful data and images you can give us!
