    Any ol' eyepiece will do you. No filters required.

    I would recommend staying with an eyepiece that yields an exit pupil no greater than around 5-6mm as viewing the bright blue sky will cause the shadow of the secondary mirror to show up in the FOV with too much exit pupil.

    To determine exit pupil, divide your aperture (in millimeters) by your magnification.

    And most importantly, watch out for the Sun! If solar observing is your goal here, please ensure you have the proper solar filters (glass or film) securely in place, and your finder scope(s) is either capped or filtered as well.

    And remember that your reflector telescope will show images upside down, which takes a bit of getting used to in the daytime when you see trees in the sky and clouds on the ground.

    Actually, if you can catch Venus during the day, you may get a better view because it won't be so glaringly bright.
