taken by Gianluca Masi, Ceccano (FR) Italy


31 March 1997. This is a two frame mosaic, taken from 20.08 to 20.10 U.T. Each frame 30 sec exposure. Reflector 15 cm f/5, CCD SBIG ST-7. Log-scaled.



31 March 1997. This is a three frame mosaic, taken from 19.01 to 19.06 U.T. Each frame 1 min exposure. Lens 180 mm f/4, CCD SBIG ST-7, elaboration MiPS32.



26 March 1997. 19.10 U.T. 3 sec exposure. This image shows the inner region around the nucleus, with dust waves. Reflector 15 cm f/5, CCD SBIG ST-7, elaboration: QMiPS32.



21 March 1997. This is a nine frame mosaic, taken from 3.22 to 3.59 U.T. Each frame 1 min exposure. Reflector 15 cm f/5, CCD SBIG ST-7. Log-scaled. This is one of my best results.



21 March 1997. 4.31 U.T. 1 sec exposure. This image shows the inner region around the nucleus, with dust waves. Reflector 15 cm f/5, CCD SBIG ST-7, elaboration: QMiPS32.



21 March 1997. 3.23 U.T. 1 min exposure. This image shows the hidden comet features, as severel jets near the nucleus.Reflector 15 cm f/5, CCD SBIG ST-7, elaboration: QMiPS32 (Larson/Sekanina algorithm).



20 March 1997. This is a seven frame mosaic, taken from 18.37 to 18.59 U.T. Each frame 1 min exposure. Reflector 15 cm f/5, CCD SBIG ST-7. Log-scaled. This is one of my best results.



20 March 1997. 18.05 U.T. 1 sec exposure. This image shows the inner region around the nucleus, with dust waves. Reflector 15 cm f/5, CCD SBIG ST-7, elaboration: QMiPS32.



12 March 1997. This is a four frame mosaic, taken from 3.16 to 3.28 U.T. Each frame 1 min exposure. Reflector 15 cm f/5, CCD SBIG ST-7. Log-scaled.



12 March 1997. 4.18 U.T. 30 sec exposure. This picture shows the coma around the nucleus. Pseudocolors have been used to underline the brightness levels. Reflector 15 cm f/5, CCD SBIG ST-7. Log-scaled.



11 March 1997. 18.22 U.T. 30 sec exposure. Reflector 15 cm f/5, CCD SBIG ST-7. Log-scaled.



9 March 1997. 18.11 U.T. 60 sec exposure. Reflector 15 cm f/5, CCD SBIG ST-7. Log-scaled. Perhaps, this is the first Hale-Bopp image in the world taken in the evening sky.



3 March 1997. 4.42 U.T. 1 min exposure. Reflector 15 cm f/5, CCD SBIG ST-7. Log-scaled.
