Wow!  20 inches of pure beauty! :-)  What's amazing is that it looks like it might even be a triplet - unheard of in that size.

I have a feeling that, without even putting it in a telescope, that lens would crush my mount! lol.gif

My goodness! The focal length on that monster will be around 21 feet! If you were to put a camera on the receiving end of that, even a KAF 16803 with its 9 micron pixels and 36mm size would require a 9x6 panel mosaic yielding 0.29 arc seconds per pixel in order to capture Andromeda. What a beast that will be.

It's a 51cm LZOS APO. This is a old photo I ran across while looking at LZOS glass threads and thought it was worth a bump.
