Sorry Nitro, I must protest !!! In the right time of the year, on a clear night, you can see the Andromeda-galaxy with the naked eye: 2.2 million lightyears away !
With about 68,280,275,350,000,000,000,000 feet distance, it is the most distant object that can be seen with the naked eye ! :crackup
Actually, that's not true. It is a common misconception that the Andromeda Galaxy is the most distant naked eye object, but it is really the most distant object that can be easily seen (since it can be seen even from rural areas with lights nearby).
From a really dark site you can also see its slightly further companion M33 which is 3M LY away. But even that is quite close compared to M81, which can be seen from a very dark, clear site and it is just under 12M LY away.
M81 held the record for the furthest naked eye object until March of 2008 when that record was obliterated for a brief few hours when a Gamma Ray burst in the constellation Bootes reached nearly 5th magnitude (well within the range of human vision from a reasonably dark site).
The Very Large Telescope in Chile and the Hobby-Eberly Telescope in Texas measured the burst's red-shift at 0.94. A redshift of 0.94 translates into a distance of 7.5 billion light years (yes, that's BILLION with a "B"), meaning the explosion took place 7.5 billion years ago, a time when the universe was less than half its current age and Earth had yet to form.
And now back to our regularly scheduled topic.
Great pics Nitro!
It's really great to see comparisons of all the different types of lights under similar and relatively controlled conditions. Thank you so much for all the hard work!
How would you compare the throw of the Mag60 to the Mag85? The 85 clearly puts out more light, but the the WA 1160 lamp seems to focus tighter.
