Object : Comet Hale Bopp C/1995 O1
Date : 1997-03-06
Time (UT) : 20:00 ??
Lens/telescope : Konica 135 mm f/3.5
Field (FOV) : 15x10 degree, before cropping
Filter : B2
camera : Konica T3
Film : Kodac PJM-2, 640 Asa
Exp. time : 30 seconds on tripod
Image process tool : Gimp, IrfanView. Film scanned at 2400 DPI 48 bit (3x16).
Processing : Correct for the vignetting and background. Increase the contrast a lot.
Site : Sweden Saltsjöbaden. Bortle class 6
Comment : This is a later attempt to process the image a bit better. The film is scanned at 2400 DPI and with 16 bit depth each channel. The big problem is to get rid of the background to get the weak details in the tail visible.

Comet discovered 1995-07-23, then it was outside Jupiter's orbit.
Earth closest approach 1997-03-22, 1.315 AU.
1AU (Astronomical Unit, distance Earth-Sun)=150million kilometers.
The blue tail is the plasma tail and the white is the dust tail. The blue tail is always pointing in the direction out from the Sun.

Only one year after the super bright comet Hyakutake we got this, comet Hale Bopp with the brightness peaked at magnitude -1 too.
