Latest wide-field CCD image shows delicate ~3o tail, recorded in the light of singly-ionized water ions. It was taken with the Zeiss 2.8/180mm lens and narrow-band H2O+ filter centered at 620nm (FWHM=10nm). Exposure lasted 10 minutes. Acquired during the short dark gap between the Moonset and dawn. The colors on this and all subsequent images are false and were used in order to enhance the comet tail structure.

The northward motion of Comet Hyakutake against the background stars is seen in two photographs of the same portion of the night sky taken 24 hours apart. The left photo was made at 5 a.m. EST on March 3; the right photo at 5 a.m. EST on March 4. Both photos were made with a 12.5 inch F/4 Newtonian reflector. Both are 10-minute exposures made on Fujicolor SG-800 film. [The March 4 image was made in strong moonlight].

These images were taken in broad moonlight! Latest close-up view of comet, recorded in the light of singly-ionized water ions. It was taken with the 36-cm, f/6.8 S-C telescope, CCD and narrow-band H2O+ filter, centered at 620nm (FWHM=10nm). Exposure time was 5 minutes. Note the faint wavy ion tail, extending to NW direction.The colors on this and all subsequent images are false and were used in order to enhance the comet tail structure.

Take a look to another R-band image, taken with the 20-cm, f/2 Baker-Schmidt camera and ST-6 CCD.

100 sec exposure. North is up in this 23' X 15' field, a false colour palette is used to show the extent of the faint parabolic envelope. The brightening on the far right of the image is due to scattered Moonlight in the telescope. Taken with a 25cm f/4.1 Newtonian and HI-SIS 22 CCD.

The image was taken with an ST6 CCD camera attached to a 25cm telescope working at f/6.3. Focal Length of approximately 1600 cm. The Field of View of the image is approximately 14' x 10' (arcminutes). This is a track & accumulate image of 10 each, 60 second exposures, with guiding locked to the comet's coma.

Image taken with a 6" f=500mm Flat-Field-Camera. Exposure was t= 30 seconds and the picture was first croped and then resampled. A longer exposure was not possible, because the moon was standing nearby the comet.

False color image taken on a 180mm refractor at f/9 with an ST-8 ccd camera. The image is the result of (20) 30 second images with a mean exposure time of 08:24 UT. The comet is obviously much brighter but the image quality suffers from the proximity of the moon.

Date: March 10, 1996 03:39 UT

For this image we used the ASTRIANE camera build with a Thomson 7863 CCD device at the Nasmyth Cassegrain focus of the 105 cm telscope. The exposure time was 20 minutes. This image is the result of substraction of two narrow pass band filters (fwhm = 10 nm) in the red part of the spectrum. Then the dust continuum is removed. The jet position agrees with the rotational period derived from february 19th observations. North is up and west is on the right. The comet was at 0.515 UA from the Earth.

Latest wide-field CCD picture of comet Hyakutake, recorded in the light of singly-ionized water ions was taken with the Zeiss 2.8/180mm lens and narrow-band H2O+ filter, centered at 620nm (FWHM=10nm). This image is composition of two co-added frames and was processed by Bojan Dintinjana. Cumulative exposure time was 12 minutes. Take a look to another R-band image, with the 20-cm, f/2 Baker-Schmidt camera and ST-6 CCD.
