Right panel: Real image taken with the Wide Field/Planetary Camera-2 of a "globular duster" pinhole mask in the April 1993 WFPC2 Thermal Vacuum test at JPL (Pasadena, CA). The image is a 80 sec exposure through the F555W ("V") filter about 40x34" on a side, and approximates closely what HST+WFPC2 should see in a few-orbit exposure after refurbishment on a distant globular cluster (like Omega Centauri, but up to 70x further away). This HST image has a resolution of ~0.10 (FWHM), or about 10x sharper than can be ordinarily achieved from the ground. Note the apparent lack of spherical aberration wings in the expected refurbished HST image, and that individual stars can now be distinguished for the first time down to the very cluster center. The faint cosmic-ray streak in the middle of the left edge shows that this is a real (WFPC2) CCD-image.
