Video Camera Filters?

I find the DeepSky and visual light pollution filters work well in light light pollution. In moderate light pollution the Deepsky and the imaging light pollution filters (Orion Skyglow imaging, Hutech IDAS LP series, Astronomik CLS-CCD) are a good choice. In heavier light pollution the Astronomik UHC is quite effective with a video camera. Then there are the narrower band specialty filters (OIII, Ha, Hb) which also work very well under heavy light pollution.

The Orion Photographic SkyGlow filter has worked well with with my IIE and Sammy 425 cam. The Ha filter is awesome for emission nebs, SN remnants and any other hot Ha regions.

With filters, you'll need to be able to increase the cameras exposure, or the amount of light getting to the cameras chip to compensate for filtering.
With a full on IDAS LP2 filter, Orion Sky Glow filter, or a UHC filter attached to something like a Samsung SCB2000 or 4000, you've basically added a lens cover.
It's 8.5 second exposure is far less than needed to compensate for the reduction in light on most objects other than the moon (and you won't need an LP filter for the moon).
With a Mallincam (like the MC Extreme) you have nothing to worry about, only now you'll need to have a great mount that can track a bugs butt for the longer exposures
Hope that helps you...
