Test of the new 2" Baader U Filter (UG11xx)

A comparison of the new 2" Baader U Filter (UG11xx) against the older 1 1/4" predecessor (UG11x).

Images 6 + 9 show, that the new one (UG11xx) has about 5 stops better IR suppressing capability than its predecessor.

Images 7 + 8 show, that the new one (UG11xx) has about 10 stops better UV transmission than IR transmission.

Regular exposition is about +8EV to +10EV as compared to a white light shot.

1st Row: Baader U-Filter 1 1/4", older type, UG11x
2nd Row: Baader U-Filter 2", newer type, UG11xx
3rd Row: Exposure equivalents
4th Row: on hotspots, VIS, UV, UV
5th ROW: ditto, differential images VIS-UV

For first 2 Rows:
1st Column: UV+IR response
2nd Column: UV only
3rd Column: exposure comparisons

Note also the much better flare/hotspot suppression of the newer type.
Even direct sun shots are possible now due to the very high IR suppression.

The later shots show different topics ....
