Club Penguin How To Rainbow Puffle

(Cádiz) on 15-05-2010


On May 15, we take both my friend Javi Jare like me to make an observation from the Picacho area, in the Natural Park of the Acorns in Alcalá the Gazules (Cádiz). The observation I make with my Meade LB 12 "as always, Javier Jare also has one like mine but more modern, and we can go comparing objects with different eyes we have.



The first object we see is the Caldwell 7 or NGC 2403, is in the constellation camelopardalis with a magnitude of 8.90. To watch her use the eyepiece Meade 4000 26 mm (x59) is a very large and bright galaxy, has many stars around and also even within the galaxy can see stars, so that the image we love. By using the hyperion of 17 mm (x90), the image is greatly improved because he observed more details, you better distinguish the central structure of the galaxy, stands very well the core, and even His arms look much better.


After Coma galaxies observed two Beren, the Caldwell 36 and 38 or NGC 4559 and 4565 of magnitude 9.9 and 9.6 respectively. The two galaxies are close to each other and fairly well observed, I use the 17 mm eyepiece hyperion (x90), the NGC 4565 this galaxy eye is very thin and beautiful to watch. We also note another galaxy that is near the 9.9-magnitude NGC 4494 even more tiny.


The next galaxy we see through the hyperion of 17 mm (x90) is the NGC 2841, in the constellation Ursa Major, with a magnitude of 9.3, is observed by a number of bright stars that makes the image is Very nice.


The next galaxy is also in the constellation Ursa Major, NGC 3184 is and its magnitude is 9.8, the note also with the hyperion of 17 mm (x90), the galaxy is large and is seen as a stain, a smear rather weak and there are a number of star by serving as a reference to observe. The area is also the galaxy NGC 3179, which is very tiny, use the stars as a reference to just watch and I can see in lateral view it is very weak (magnitude 14.1).


Now it's the turn of the galaxy NGC 3877, we in the Big Dipper and has a magnitude of 11.90, to observe the hyperion still use 17 mm (x90) has elongated and looks very pretty to the eye. The area has more galaxies and do a tour of the area of \u200b\u200bthe sky, the first thing I see is the NGC 3893, the galaxy I see around, but when observed in lateral view, I see very strong central zone, when viewing a picture, I see that this is a galaxy with a very prominent nucleus, and perhaps what I saw in the observation.


I continue on the Bear with the galaxy NGC 4088 in the area there are many galaxies and try to identify some more such as NGC 4157, which I can also observe. Next to the first, I can see the galaxy NGC 4085, which at first I unnoticed, but then I can see, I always use the 17 mm eyepiece.



now I continue with the galaxy NGC 3432 of 11.30 magnitude and located in Leo Minor, use the eye 17 mm as always, stands out pretty well although it is a faint galaxy.


Then take the opportunity to observe Markarian chain 4000 in Meade eyepiece of 26 mm (x59), here I am enjoying a good time with the chain, but had already observed at other times, I never tire of seeing this area of \u200b\u200bthe sky with Meade LB 12 ". I have also observed the galaxies NGC 4608 and 4596, ending for the night.


That night I could also take some photos of the ashen light of the moon that you see on the blog in the following address:

ashen light of the moon from the Picacho on 15-05-2010

The Earthshine is weak light that illuminates part of the lunar disk not bathed in sunlight and that without it would be invisible from the Earth .

is especially noticeable during the first and last days of the lunar cycle when the Moon's sunlit Earth visible from the is very small or nil, if the moon is under age new . Then, almost all the Earth's surface is visible from the moon bathed by sunlight and reflects part of that light to the moon (the albedo of Earth is 0.39). In sum, the ashen light is in the lunar soil, which in light of the moon is to us shortly before, during, or shortly after full moon . Since Earth is much larger than the Moon, it enjoys a night light so intense that for the afterglow that in our world, preceding the arrival of the night .

The photos are taken from the Picacho in the Sierra de Cadiz in the Natural Park of the Acorns, also took advantage of Venus was about to get the whole picture from different points of view. All are made with the tripod and the Canon EOS 1000D, exposure times and ISO used place them in the photo.

Paronámica to view the ashen light of the moon and Venus above. Exposure of 5 sec. to ISO 400.
