Nitpick: The refracting telescope, drawn correctly, has a mirror in the optical path (image inverter), but it is made with a special vampire reflecting material Ichorium. Doesn't the one in this image have a mirror too? at the bottom to make the image come out at the side instead of the end? 162.158.89.187 Something went wrong on my comment - only the part after "doesn't" is from me, the part before was what i was commenting on, idk why it is not seperated 162.158.89.187

That's a good point: as drawn, the refracting telescope still has a mirror and also wouldn't be able to see space vampires. However, the refracting telescope doesn't have to have a secondary mirror, and there are plenty that don't, so it is more the drawing that is wrong rather than the text of the comic.Cmancone (talk) 14:31, 27 January 2017 (UTC)

Typically refractors use a prism rather than a mirror at the end, though it does the same thing. Can vampires be seen in a prism? 108.162.241.172 14:50, 27 January 2017 (UTC)
