   5 Tips for photographing the moon
  
   1: Sturdy Tripod
  
   Stability is key for photographing all
   celestial objects. Make sure your tripod
   is heavy, most have a loop or hook you can
   attach a heavy object to the bottom. A bag
   is a good choice, keeps it out of the mud too!
  
   2: Longest lens you have
  
   The Moon is smaller than you think in the sky.
   Take advantage of some cheap doublers and you can
   get really close. Remember that long lenses are
   not sharpe at there extremes so dial it back a bit
  
   3: Spot metering
  
   Set your camera to spot meter and make sure you
   your viewfinder on the Moon, you can then expose
   correctly.
  
   4: Dial in the exposure
  
   Similar to shooting in snowy conditions it is a
   good idea to increase the exposure compensation
   to counter for the bright light coming from the
   Moon. +1-2 should do it for a full Moon
  
   5: Shoot when the Moon is Waxing or Waning
  
   As the Sun shining from the side this casts
   shadows fromt eh craters and emphasises the
   ball shape of the Moon
  
   And now for some evidence to the above!

   What a month for astrophotography!
  
   Spent 4 nights in the Scotland Dark Sky Park
   with a couple of visits to the observatory for
   a spot of meteor hunting and astrophotography.
  
   It was a very successful trip, had a great time
   with Jennie looking at the stars together.
  
   I learnt something over the course of the holiday
  
   "Be prepared!!!!!"
  
   So for our planned trip to Reykjavic in March
   we need better boots to keep our toes warm in the snow.
  
   I sought help from my Canadian friend and purchased
   a couple of pairs of Sorel Caribou Wool lined boots.
  
   Very snug!
  
   To play us out, here is the best photo I have ever taken

   Second entry - 500 rule
  
   I'm storing this here as I always forget it.
  
   To avoid star trails with astro photography
   apply the following formula
  
   t = 500 / f
  
   where:
   t: Shutter speed in seconds
   f: focal length of the lens
  
   eg: What shutter speed would I use for a 24mm lens?
  
   t = 500 / f
   t = 500 / 24
   t = 20.83333...
  
   a 20 second exposure should ensure no star trails
  
   Enjoy

   My First entry in this new astro section.
   The layout could change so hold on for now
  
   I intend on listing my astro adventures here,
   mainly failures but some successes
  
   Wanna see my 8 incher?
  
  
  
   That is all for now.
