Description

UNGUIDED
CDK20: FL 2280mm,  F/4.5,  0.34 arcsec/pixel raw
Moon:   60%

This image from NASA is the first ever published image taken by the James Webb Space Telescope with the 18 hexagonal primary mirror segments fully aligned.  The precision and detail of this image are breathtaking, foretelling the amazing images that will follow.

NASA's image:
An image of the star 2MASS J17554042+6551277 taken by the James Webb Space Telescope that confirmed the performance of the spacecraft's optics. The rays are diffraction patterns from the shape of the mirror segments.

From NASA:
NASA announced March 16 that spacecraft team had finished the “coarse phasing” and “fine phasing” steps of alignment of the telescope’s optics. Those steps involved very small changes in the positions of JWST’s 18 primary mirror segments such that their images were aligned on top of each other and then matched to within a wavelength of infrared light.The completion of the fine phasing means that the telescope is now fully aligned for one of its main instruments, the Near-Infrared Camera, and that there are no flaws like the spherical aberration in the primary mirror of the Hubble Space Telescope that diminished its performance after launch until corrective optics were installed.

=======FINAL Image========
My image of the same star uses the same FOV as the JWST NIRCam alignment image.
In addition to the bright central star, my image shows 'something' for 12 of the very small, likely galaxies that appear in great detail in the JWST image.  And my image presents the bright central star enormously bloated in comparison.

The JWST image is taken with the NIRCam camera.
The FOV of this first published image is 2.9' x 1.8' arcminutes.

NIRCam/JWST specs:
Mirror Diameter:  6.5 meters
Focal Length:        131 meters
Focal Ratio:            f/20.2
Field of View:     4.4' x2.2' arcminutes
Sensor Pixels:    4096 x 2048 pixels ( 2 each 2048 x 2048 )
Pixel Size:           42 microns square ( 125 times area of ASI6200mm pixels )
Sensor Size:       170 mm x 85 mm
Resolution:        0.064 arcseconds/pixel  ( CDK20 resolution / 5.3 )

=======ORIGINAL Image ========
My full sized original image FOV:  49' x 40' minutes.
It is rotated 8.5 degrees clockwise to line up with the JWST image.
Image center ....... RA: 17 55 40.301 Dec: +65 51 28.20
Star:  2MASS J17554042+6551277
The bright alignment star is in the exact center of the image.
