Hi all,
I don't expect the weather to play ball this weekend, but on the off chance that I get a glimpse of the Moon during the partial eclipse I'd like to ask a question:

From past experience with partial eclipses it seems that they can range from hardly detectable to quite colourful and distinct. I was wondering whether there are any filters that could/should be used for visual observation that would would enhance the experience for people that are not used to telescopes and observing the the Moon (as in: friends and family).

I have previously never used any filters during lunar eclipses, but I wonder whether I should have. Therefore, if anybody would like to add their 2 cents regarding colour or polarising filters for use on small to medium scopes (up to 8") I would appreciate it very much.

Cheers
Steffen.

This is a really good question :thumbsup: and I will watch the responses with interest. :) I can't wait to see my first lunar eclipse with my scope :D.

Oooo! - thanks - I'd forgotten about this
Wish it was a week later :P, but might be able to snap some shots.

Looks like Dec next year is the last total for quite some time too.

I haven't observed an eclipse for many years, but recall binocs where as good as anything. Under power, the moon still looks the same, but with fainter and tinged colour. Colour depends on how much dust etc in our atmosphere. Expect if its partial we're more likely to see shades of grey than orange. Also eagerly await advice from the gurus.......
