What filters do you use ?

[Neiman]

Hiya, I’ve just purchased a manual 5 filter - filter wheel. I know I need as a minimum r,g,b and maybe l. What make as there’s a few out there ? What make do people use ? I have been looking at baader ones.

Any help would be appreciated.

Cheers

Neil

Where do you image from Neil ? I ask as I recently did the same thing, went mono and bought a 5 position wheel, R G B L and Ha ... Then saw how amazing Ha was in light polluted area and ended up ditching the R G B and buying Oiii Sii and Ha. ZWO 1.25" and very happy with them ( make sure you get the newer version as Oiii has reflections greatly reduced)

I've always enjoyed the results from my Baader filters, they work well and are sensibly priced.

In recent times more brands have been introduced. It's just an assumption but I would guess at them coming out the same production facility and just being rebranded.

I will be going down the back garden route. My area is a 6 on the Bortle scale.

I use Baader 2" mounted - L - R - G - B - Ha - Sii and Oiii

If you have a 5 position wheel I would try LRGB and Ha to start with.

I am very happy with my Baader filters - sure they are not Astrodon quality but they are a fraction of the (eye watering) Astrodon price !

How do I decide which size I need ?

Camera chip size and telescope ... Bigger chip needs 2" smaller chip 1.25” as a very rough guide, so long as the filter will cover the chip without casing vignetting you should be ok.

Wonder if someone can answer this - are 2” filters mor commonly used with DSLR’s than cmos / ccd camera’s ?
