i had a quick peek at the moon the other night with a normal green moon filter it was still too bright and i was wondering what you would recommend as in a different color filter perhaps ? (full moon)
doh I tried posting this and then the site had a hiccup for a bit.
You need a neutral density filter - the coloured ones will probably work a bit, but the ND ones would block out more of the right wavelength I assume.
If you want to spend a bit more, you can get a variable polarising filter, which lets you "tune in" the amount of light reduction you want, from something like 9% to 30% I think.
Also remember that any filter is going to reduce detail, even if it's only a slight amount. But I suppose if you're looking at the full moon it's not going to make that much difference in detail.
I have a standard moon filter plus a range of the el cheapo Celestron colour filters. My fav is the dark blue. Cuts light to an acceptable level, but doesn't make the image look murky. Scratched it last night
I sometimes stack a blue filter on top of a neutral density filter. Really cuts down the glare and seems to darken the maria nicely. On a 12" you'd need the darkest ND filter you can find, one that will block out about 90% of the light
This may sound silly... I just use my sunglasses for a quick peek of the moon. Mind you I generally dont spend all that much time looking at it (generally only when guests are over to have a stickybeak)...
