During the period from July 16th to July 31st, 2005, the Southern Bay
Area was blessed with a string a extremely clear nights which allowed
to take 15 consecutive images of the moon. The instrument used was an
Orion Apex 102mm Maksutov-Cassegrain Telescope, mounted on an AZ-3
(alt-az) mount with a Celestron 32 mm Plossl eyepiece and a Konica
Minolta DImage Z2 camera. All images before the night between the 23rd
and 24th were taken by manually holding the camera to the eyepiece.
Afterwards, I used an Orion SteadyPix adapter which allowed me to take
longer exposures of earthshine and star clusters.
The moon rises approximately 45 minutes later every night, and at my
house the moon (actually all objects near the ecliptic) must rise over
a hill. When one considers that it takes between 15 minutes and a half
hour to take a sufficient number of images to be assured a reasonably
clear one, I finished imaging approximately 90 minutes after the
actual moonrise time. As a result, near the end of the project I had to
stay up until 3:30 AM to image the moon and I wasn't getting to bed
until around 4:00 AM. I always tried to image the moon as late as
practically possible so as to limit heatwaves and minimum the amount of
atmosphere the moonlight had to travel through.
The images below are those that I subjectively judged as best for each
given night. The DImage Z2 does not have a raw mode so they were
acquired on the best JPEG setting. Almost all had a brownish orange
tint so I adjusted levels in Photoshop and ran an Unsharp Mask to bring
out more detail.
Images
Notes: Dates given above each
image refer to the night that the photo was taken with the bold
indicating which side of midnight the image was taken on. For instance
"July
20th to 21st" means that
the image was taken on the 20th before midnight. I use this method to
avoid confusion. Otherwise, it is unclear if an image taken on a
specific date was taken early in the morning (1 AM) or late at night
(11 PM).
The Others link will link to a directory with the original
(unprocessed) images for that day. These directories often have images
of other celestial objects or special shots of the moon.
