I'm considering purchasing a 70-300mm lens and a 1.4x TC to try some budget deep sky photography. I have seen some great pictures of the Orion Nebula taken without a telescope.
My question is: can anyone name any nebulae or objects that can be taken with this setup? It's quite difficult to search for photos taken without a piece of equipment rather than with, so I'm not sure of the possibilities of this working and whether it's worth the money.
I don't have any filters at the moment but I plan on buying some if there are enough objects worth the effort.
