Well, I must have been the first one (possibly still the only one)
who shot HIE in a Noblex 150, with Rolland Elliot's cut down
220-format....:))
And that's after several years of shooting HIE with a Horizon 202, in 
35mm format.

Check the URL in the admin-footer below for a few more dazzling shots, in a 
sublimation (pun intended, you'll see why) of IR, panorama and snow 
landscapes.
Can't scan the 50x120mm frames taken with the Noblex 150 yet, but I 
hope to solve that in the near future with a Leaf 45.

To my surprise, even the Noblex 150, with 50mm/f4.5 lens, fix-focus, 
set to infinity, has no focus problems with HIE, not even with the 
#87C I used.

You won't find any regular available filters, but since I ran into
this problem many years ago, I decided to fabricate them
myself....since then I have made several #25 red and #87C infrared
filters for the Horizon 202 (factory filters are only UV,
yellow/green and ND2x), as well as #87C for Noblex 135 and 150.

As sandwich (foil behind UV filter) #29 and #89B are possible, in 
gelatine even the darker #87B and #87A.
Since all these panorama cameras have a separate viewfinder, the 
darkness of the filter is irrelevant for composition or focus....you 
can shoot as dark as you want, without affecting camera operation.

With the 202 and #87C, I typically shoot a bracket range of 1/60s @
f5.6-11, but since it also offers a nice 1/8-1/4-1/2s slow range
(unlike most other brands), darker filters are no problem in that 
department either.

If you are interested in any of this, or even buying a brand new 
Horizon 202, mail me privately.
(I currently also have a Noblex 150 for sale)

On my homepage you can also find tips & tricks about darkloading the 
202, and how to mount and dismount filters (there are smarter ways 
than described in the manual).
