Stacking filters

[Tron]

Is there anything to benefit from stacking narrowband filters?

Stacking how, and to accomplish what?

To get a narrower band?

Yes is this imaging or visual?

Both

So stacking two or more of the SAME filter will give a benefit of a narrower band?

Is there a list somewhere of good combinations of stacking that work?

Derp, nevermind...

[MjrTom]

I'm pretty sure it does not really work like that.

The band pass is constant you don't get a cumulative effect by stacking them

Not sure that works. Filter 1 lets through Xnm bandpass at Ynm, filter 2 lets through the same .... no benefit?

If you had a filter with a wider bandpass and a narrower bandpass, well why not just use the narrower one to start with?

To get a "narrower" band, you want a filter with a narrower bandpass?

Just wondering as I see solar filters sold as single and doubled stacked for narrow bands.

Double stacking is the equivalent of putting a narrower bandpass (though I'm not sure if that is the correct term for slare) filter in front of a wider one isn't it?

So why bother with a wider one if the narrower one is blocking all you need

The narrower ones are a rather expensive upgrade option on an already expensive piece of kit

It's also limiting as solar shows different things at different bandpasses, the double stack may show prominences but hide surface details.

This is all from Google, I may be horribly wrong

stacked filter 1.25 - Google Search

Google shows stacked 1.25" filters in its results...
