Which camera lens for Piggyback astro photos?

Yes, I do. Very good lens, especially for the money. Seems to be the best-bang-for-the-buck Canon lens money can buy. Good for astrophotography.

The canon EFS F1.8 mk2 50mm seems too good to be true at about 100 yoyos.

Its a great little lens. Got mine off some bloke in HK on ebay.

Anthony, do you have any side-by-site comparisons of images taken with and without a fog filter. I'm curious to see the effect that such a filter would have.
