Nothing to do with rangefinders, but fascinating nevertheless - Rolf Olfsen from New Zealand has created what's likely the deepest ever amateur image of the Centaurus A Galaxy, according to southern hemisphere astrophotography forum Ice In Space.

The large 4Mb image is quite stunning in its clarity, given the galaxy's 10-15 million light years distance from Earth and given that it was taken with a 10" telescope in Auckland, New Zealand. Rolf's explanation of his technique is described here.

Sometimes it's nice to appreciate the work of dedicated amateurs in other fields of photography.
 
As an old stargazer that used to take photos with his Nikon Fe thru a homebuilt 6"
Newtonian telescope, I can hardly imagine the effort necessary to take these pictures !!!

Awesome! I still recall the old good days using hypersensitized film in my Canon F-1, mounted on top of my 8" Meade 10LX. Now that I have "grown up", the everyday's monotonous rush for things has blasted away all this magic from my life!

Dedicated amateurs improve every field possible, not just photography. Those that have to keep their faculty position rarely worry about the really big important things.

This is one of the only recent correct usages of the word "awesome." Usually applied to my entree choice by a waiter...
This is truly awesome!

Quite true. Or if you do worry about big things, you are likely not very successful.

Lynn, thanks for posting that. I had no idea that an amateur could produce an image like that, although the data collection sounds like a true tour de force. I was not aware that cooled CCDs were in use by the 'general public', now I see that you can buy them online!

Makes me wonder how many other hidden worlds are out there?
