First image was taken with an Olympus OM-4 with a 200mm telephoto lens mounted piggyback on a 3-1/2" Questar telescope. Exposure was approximately 180 seconds on ISO 200 film. This is not a very interesting photo of the comet, but is interesting for the object which crossed the junction of the coma and the tail during the exposure. Second image was taken with a 200mm telephoto lens Exposure was approximately 240 seconds on ISO 200 film. Adobe Photoshop was used to convert the color image to grayscale and then to invert it to a negative.

Third image is a 0.05 second exposure taken at 04:31 UTC also at low res. Note the activity near the nucleus. Fourth image is a 1 second exp at High Res. (10 x 10 Micron pixels) taken at 04:08 UTC. Fifth image is a 1 second exp at high res. taken at 04:07 UTC processed in false color. All images have been flat fielded. The reason for the low resolution images is that the high res images took too long for the track and accumulate mode to keep up with the rapid movement of the comet.

These are NASA Hubble Space Telescope images of comet Hyakutake (designated C/1996 B2), taken at 8:30 P.M.. EST on Monday, March 25 when the comet passed at a distance of only 9.3 million miles from Earth. Unlike most of the published images of Hyakutake, these Hubble images focus on a very small region near the heart of the comet, the icy, solid nucleus. The Hubble images provide an exceptionally clear view of the near-nucleus region of comet Hyakutake. The images were taken through a red filter with the Wide Field Planetary Camera 2 (in WF mode). The sunward and tailward directions are at approximately the 4 o'clock and 11 o'clock positions, respectively. Celestial North and East are at approximately the 5:30 and 2:30 positions, respectively.

Date: March 27, 1996 01:03-02:22UT
These images were taken by Herman Mikuz and Bojan Kambic from a dark site at Slovenske Gorice, 170km east of Slovene capital Ljubljana. On otherwise cloudy Central Europe, the weather satellite shows a small gap approaching to NE Slovenia. We traveled to this distant site and indeed enjoyed a 3-hr clear period. We were both impressed due to the splendid Hyakutake display. With the naked eye the tail spanned for 45 deg, up to Beta CVn and the estimated comet m1 was 0.4 magnitude. All images were guided on comet nuclear condensation.

The set shows four different views of the same image. The upper left image is a negative of the original using an unsharp mask to help bring out details.

16 images of 5 sec. each were averaged after an appropriate shift in order to align the nuclear condensation. Original images were obtained with a 135mm (f/1.8) telephoto lens and a SBIG ST6 CCD camera, piggy-back mounted on a 10" LX200. Images from left to right represent a linear stretch, a log processing, and the result of subtracting a blurred log image from the log itself. This last processing clearly shows jets originating from the nuclear condensation. In the second picture the "tail" jet is apparently separated from the nuclear condensation (a result of the reported nuclear fragmentation?)
