RE: Star Trails on Infrared?

[Ron Aavang <Ron_Aavang@xxxxxxxxxxxxxx>]

Is it worth shooting the concentric circles of stars on Konica Infrared?
The idea is to shoot a barn with the stars haloing around it.  Will I get
anything on Konica that I won't get on TMax?  Is there any Infrared when
the sun don't shine?

Grazie,
bob

	I am curious now. Has anybody tried to hyper HIE or Konica 750 to
shorten the exposure at night for astrophotography or any other photo that
takes a long exposure time? Did it help? If it did, what was the hypering
recipe you used? It seems to me it should help when using a deep near IR
filter to shorten the exposure time by decreasing the reciprocity failure.
