I had a 1.25mm Herschel wedge with one filter which when rotated changed from white to yellow. I plan on getting another one after Christmas as I sold it and wanted to know what filter to get a continuum or polarising does it make any difference thanks.

Get both. I use both as being able to adjust the brightness helps a lot. Just a single polarising filter needed. Some cheap ones on Amazon or eBay but I use the Bresser which is similar quality to the Baader but cheaper. The continuum filter doesn’t have much effect on the brightness but just adds a bit of extra detail.

I just use a single polarising filter with my Lunt 1.25 inch Herschel wedge. On the bottom of the eyepiece, you can control the brightness of the image by rotating the eyepiece. The light comes through the wedge polarised in one plane so you just need the single polarising filter between it and the eyepiece.

I did say use a single one and rotate the eyepiece that is all I used when I had mine.

The link is to the Orion double polarsing filter which can be used individualy as well.

I use the Bresser single which may be better quality than the Orion double.
