    I have used Tri X for astrophotos in the past but want to get away from
    kodak and use Ilford. Which if their B/W films is the one that is almost the
    same or better than Tri X. I don't want to use Delta,I want the old style
    Tri X type film.

  2. HP5 Plus is the closest Ilford has. It's better in some ways and worse in
    others. Give it a try and see if it fits your application.

    The most important thing will be reciprocity failure. In this regard,
    surprisingly, Kodak T-Max 100 is a better film than any of the ones listed
    here. It is faster than Tri-X during very long exposures because Tri-X has
    more severe reciprocity failure. The same exposure on T-Max 100 as on Tri-X
    will result in an image with fainter objects recorded.

    If you want good reciprocal behaviour then go for Fuji Acros. The data sheet
    states that no correction is needed for exposures up to 120 seconds, and
    between 120 and 1000 seconds add 1/2 a stop.

  4. I have used Tri X for astrophotos in the past but want to get away from
    The Fuji Neopan 400 is very good. I burn it @ 320.
