Does anyone know of a b&w film that has good reciprocity characteristics. I was thinking about Fuji Acros neopan, but B&H only lists in in quickloads, which I am not interested in. This is going to be for testing a custom deep sky camera.

T-Max100.
You can get Acros in sheets from Badger Graphic, or from Dirk Rosler's Megaperls Webshop.
Any of the more modern emulsions. T-Max 100, 400 or Delta 100, 400. I use Delta 100 for night photography since I get the equivalent of 400 speed for long exposures and much finer grain.
Tmax 400 is what I use.

Acros
The T-Max films are better than conventional films in this respect, but do not come close to Acros.
I've had great luck with delta 100.

Acros is the best I have found and I have tried them all. Acros has very little reciprocity and up to 2-3 minutes almost none.
TMAX400!!! I have a neg which needed a 15 minute exposure on Tmax 400 - any other film, and the camera would still be in place right now...
