Herschel wedge: better than a Baader filter ?
I am considering a Herschel Wedge for using in my 80mm and 110mm refractors as an alternative to the Baader foil in front of the objective.
The Daystar Quartz ($1400==A$2000) provides a nice image, but is way too expensive for me.
I can get a Herschel for $170 (A$250), it does not show prominences and nice Halpha view as it is just white light, but it is a better (?) alternative to Baader foil.
It is really better ?
