Description

This emission nebula is located in the constellation Orion at a distance of (more or less) 3300 lightyears from my camera sensor.

The nebula was discovered in 1939 on a photographic plate taken by Harold and Charles Lower.

Harold, and his son Charles, amateur astronomers from San Diego, CA was also pioneering astrophotographers and skilled telescope makers.

The telescope that Harold and Charles constructed, an 8”, F1 Schmidt camera with a 7” guide scope, is described in the book “Telescope making”, volume 2, by Albert G. Ingalls.

I found it quite interesting that Harold Lower described a 300 pounds(136kg) mounting as “portable”(not for my back).

Books nowadays seems to be an underrated source of information and I guess that somewhere along the digital revolution, we have forgotten the magic of reading books.
