Herschelprisma, met ND 3,0 grijsfilter LS2HW 2"

Now also available from Lunt Solar Systems, a 1.25'' Herschel wedge with built-in ND3.0 (1000x) neutral density filter. The design is identical to the 2'' Herschel wedge. As with this, the new smaller 1.25'' version can be used with refracting telescopes of up to 150mm (6'') in aperture.

We also offer a matching 1.25'' polarizing filter with which the observer can dim the remaining light from the sun down to a comfortable level. Of course, in contrast to its 2'' big brother, the smaller Herschel wedge can only be used with 1.25'' eyepieces.
