First image is a long telephoto shot, using a 6x7 camera on an AstroPhysics 610mm f6 lens w/field-flattener (Traveler). The ion tail is very strong , and extends out of the frame (in spite of moonlight) -- at least 6 deg. The dust tail has become more intense (brighter and narrower), but still has an outer *fan*.

Second image is a telephoto shot, using a 6x7 camera & 75mm/4.5 lens stopped down to f4 (the same field of an 50mm lens, 35mm format). You can see the Northern Milky Way, towards Andromeda. Wow. A memorable moment.

Observer: David McDavid
Location: Limber Observatory, Pipe Creek, Texas
Date: March 13-20, 1997

Here's a panel of 3 polarization images of Hale-Bopp from Limber Observatory. In these images of the inner coma of Comet Hale-Bopp, the brightness is proportional to the linear polarization. North is up, east is left, and the field is about 2.5 arcmin on a side.

Each image was made by combining 3 separate frames taken with a Photometrics CCD camera (Thomson 512 chip) on the 0.4 m telescope at Limber Observatory, using polaroid filters with their transmission axes at position angles of 45, 90, and 135 degrees. The reduction was done with the IRAF task "linpol."

Location: Roque de Los Muchachos Observatory, La Palma, Spain
Date: March 20, 1997 05:12-06:32 UT

The Isaac Newton Group of Telescopes has designed and built a wide field CCD imaging facility, called CoCam (Comet Camera), to carry out narrow band photometry of comet Hale-Bopp. CoCam consists of a zoom tele-objetive 80-200 mm plus a CCD 2048*1024.

The first picture is the sum of two 100s, one 50s and two 20s exposures using a narrow band filter centered at 618.5nm. They were taken from 6:15 to 6:22, 6:28 and from 6:29 to 6:32 UT on March 20. The field size is 4.2*5.2 degrees. Some interesting structure is visible in front of the coma.

The second picture is the sum of four 10s, three 20s and five 5s exposures without filters. They were taken from 5:12 to 5:19, from 5:22 to 5:26 and from 5:27 to 5:36 UT on March 19. The field size is 5.2*5.2 degrees. The synchronic bands, first observed by Fukushima and collaborators from the National Astronomical Observatory of Japan, are very visible in the dust tail.
