1. Observing Faint Targets Near Bright Objects
... The concerns here are similar to those for observing bright targets; saturation and blooming of the bright companion PSF must not impact the faint target. Also, one may need to consider subtracting the PSF of the bright object, and effects which limit the accuracy of that subtraction. If the bright companion will saturate and bloom, it will be necessary to rotate the CCD so that blooming along the CCD columns does not obliterate the faint target. ...

2. Improvements in Filter Design for Removing Galactic ``Cirrus'' from IRAS Images
... Next: Star Finding and Up: Image Restoration and Previous: Multiresolution and Astronomical . ... Design improvements continue to be made in the filter developed using mathematical morphology principles for the Infrared Astronomical Satellite ( IRAS ) images. The purpose of this filter is to eliminate Galactic cirrus emission from extragalactic fields. ... With an appropriate normalization, the filter curve was applied to each pixel in the image to remove the Galactic cirrus. ...

I created the first animation entirely within the GIMP, using Filters / Distort / Map Object for mapping an image to a box, and Script-Fu / Shadow / Drop Shadow for the shadow effect. If you are curious about the parameters to Map Object, here they are: I set the X angle to 30 degrees, the Z angle to 0 degrees, and I changed the Y angle from 0 to 90 degrees in eight steps, in order to get the rotating box effect. ... We can of course do more with this animation.. ...
