(Cádiz) on 10 July 2010
After Friday's short trip, we went out on Saturday elsewhere in the Sierra de Cadiz, in this case Benamahoma, the site is also very dark but a tad further, the advantage is that it is a lot more people, and that day came many more to watch. As always, I got my LB Meade 12 "and my set of eyes.
The first objects I see at night are 29 or Caldwell galaxies NGC 5005 and NGC 5033, use the hyperion of 17 mm (x90), NGC 5033 is quite different from the core and the outer zone of the galaxy, a galaxy is large enough, the more I see another stellar appearance, although I can also distinguish the nucleus of a galaxy is much more small. Happened to observe the galaxy NGC 5005 with eyepiece optic William 9 mm (x170), this object a lot better these increases are very well defined structure, the observed too small a 17 mm Nagler (x90) and true that much improved compared with 17 mm hyperion (x90). It seems that distinguish one galaxy in the area, although I can not realize what it is and because this review had recorded the last time, can not remember the area very well.
turn now to look at a globular cluster called NGC 5466 in the constellation Bootes, the cluster is very large with the eyepiece Meade 4000 26 mm (x59) but I see it as a speck and not work out. With the 17 mm eyepiece (x90), and begins to resolve within the cluster, although much of what I see as a speck. With the eye of 9 mm (x170), I still see it as a central speck but if I see better, but I fail to resolve, occupies the entire field of the eyepiece and still see very well. If I use the 17 mm Nagler, if that greatly improves the object and I can see stars defined.
note now Cat's Eye Nebula (NGC 6543) both with the hyperion of 17 mm, such as 17 mm Nagler, I see green initially, but noting for much longer , we see that stained with something blue. With the eye of 9 mm, stands out very well, is a biggie enough ball, you will notice a kind of filament as I report that I have recorded, we also use a 12 mm Nagler (x127) and look very well, you see the outside and is distinguished structure to the nebula, as happened with the eye of 9 mm. Hyperion with 5 mm (x300), stands very well the structure, which looks good is a cat's eye.
also use the OIII filter with the 17 mm eyepiece, I appreciate very well, the filament having the structure in its outer zone. When you put the OIII filter and 5 mm, is well outside the area, but worse distinction central zone of the nebula. It seems that the filter greatly improves the outer zone of the nebula.
now I'm seeing the galaxy NGC 6503 with the hyperion of 17 mm (x90) is a large and beautiful galaxy of view, is close to a star. With the 9mm eyepiece is very well defined, the galaxy has a stellar aspect but I see some structure, a kind of bite you have in the structure, see some photos and see that this galaxy has something, but I see it so remarkable.
take that I have the binoculars to do a review of the sky by the most typical objects, I have to emphasize to M27, I see that stands out well with 10x50 binoculars. We also want to observe Jupiter, but is still quite low (they are at 3:20 pm) and affected by the turbulence, is distinguished several bands anyway. We have a blue filter and took the opportunity to view, they are bands from the north pole to the south, without the filter can also be distinguished, we also see the red spot. After seeing Jupiter, we begin to pick up and at about 4 pm, and spent two nights in a row, and the forces fail, especially as we descend the Sierra to my house.
