A 25-min exposure of Comet Hyakutake taken on 16 April 1996 (19h45 UT) by Eric Elst with the 60/90cm Schmidt telescope at the Observatoire de Haute Provence, using an unsensitized ZU-ORWO plate. The image has been scanned and slightly sharpened to bring out the fine structure in the ion tail.
A one-hour exposure of Comet Hyakutake taken on 23 March 1996 (0h UT)
by Gilbert RAU using a 35-mm camera with a 50mm f/2.8 objective lens
mounted piggyback on the 80cm OHP telescope. The emulsion used was
Kodachrome 100. The field of view shown here is approximately 20x14
degrees. North is to the left and East at bottom.
Arcturus is the bright star located at the 'kink' of the ion tail (which is
about 10 degrees long here), while the brighter star of the pair to the
immediate left of the comet's nucleus is 
Bootis. The dust tail appears weaker and is shorter.
