Motion in the R-Aquarii Jet 1991, 1992, 1993: 2-D Motion
Images from the Hubble Space Telescope's Faint Object Camera from 1991, 1992, and 1993 demonstrate motion in the R Aquarii emission jet. Since images from this period were still affected by the primary mirror flaw, the images were restored to the original design resolution using the maximum entropy method.
Motion of the R Aquarii jet from 1991 to 1993, where the maximum entropy method with convolutional constraint was used to deconvolve the Hubble images

Datasets used
-
[HST: FOC]
ID: 37 -
[HST: WFPC2]
ID: 655Wide-Field Planetary Camera 2 (WFPC2) was installed in Dec 1993 and used to obtain high resolution images of astronomical objects. This camera was removed in the last servicing mission so it is no longer in service.
