I think the IIS astrophotography calendar is a good idea, though I don't like the idea of a "competition".
But, the images have to be chosen somehow.
Perhaps I can have an entry form where people can submit their entries for inclusion, and then have a voting system where people vote their favourites.
It could be organised so that the January image has to be an image of something that's visible in January (like, M42 for example). The July image has to be something visible in July (like, M17 for example).
We could have 1 image per page (of any category), or have 4.. Divide the page into 4 and have an image for each category (globular cluster, open cluster, nebula and galaxy) on each page. I guess it's a trade-off between one large spectacular image, and 4 smaller spectacular images per page.
So, people submit their entries for each category for each month of the year and we then have a voting system where people choose their favourite.
We could have a rule that once someone has "won" a particular category/month, they can't be chosen again for any other month. This way we don't get Brad Moore images on every single page (as nice as a calendar that would be

). So everyone has a chance of getting an image on.
Thoughts?
