Daytime observers - filters?

[jjohnson3803]

For those who observe in daylight, do you use any filters to increase contrast?  I tried a #7 yellow, but it didn't seem to help much.

Thanks!

An IR pass filter is used for imaging the daylit Moon , increasing contrast and rendering the background black.

Not sure whether it works visually though ?

I do this sometimes. I find the following...

- filters that block blue light I find can help, I find green, orange, or yellow useful, but red is too dim.

- A polarising filter can help to clear atmospheric scatter.

- At small exit pupils filters that dim the image a lot become counter productive and I'll switch back to no filter.

- A colour filter may not reveal more detail but they often bring different features to my attention.

- sometimes I'll use a colour filter just to dim the image and I don't mind the fact that it's a colour filter rather than a ND filter.

- If you happen to have deep sky filters such as UHC they can be fun but they go a bit closer to blue.
