5: Photo on M31 and M45

Now I have started to collect astronomy photos with my Sigma APO 150 mm lens, my firsts photos are on the objects M45 Pleiades and M31 Andromeda galaxy.

You can examine them in detail here:

• M31 Andromeda galaxy taken with Sigma APO 150 mm lens Click here to see photo and info in detail
• M45 Pleiades open star cluster taken with Sigma APO 150 mm lens Click here to see photo and info in detail

Look and see what you think of the Sigma lens. Note, the polar align wasn't perfect.

There isn't much written about this lens used to astrophotography. For me it feels that it deliver quality without too much costs.
