Yes I saw similar advice somewhere the other day, the article I read said you MUST put the filter at the FRONT of the lens for precisely this reason. I'd recommend following such advice because there's too much at stake. If the weather is suitable I will probably just use my binoculars to project an image. Not sure if I'll bother trying to photograph it.
