OUTPUT Grazalema (Cádiz) THE AUGUST 6, Astro
This day, we went to Benamahoma as always, but we hear he had a show near and decided to throw for Grazalema area, a place that is very hidden, and away from the road, which is most important. That day, the star were the chairs, who so lovingly has currado Javier Jare, and the truth that was a triumph, because we were looking up at 5 in the morning.
first tried to observe a nebula in Hercules, but we do not, but then we go to Ophiuco and if we can observe NGC 6340 with eyepiece hyperion of 17 mm (x90), a these increases is like a star I've seen out of focus and through referrals from stars I have. With the eye of 9 mm (x170), is still viewed as a star out of focus, it looks a little older and you appreciate a diffuse part, but not spectacular as others see it.
Then we
the nebula NGC 6210 with the 17 mm Nagler (x90). Also note with my hyperion of 17 mm, although it shows the quality of the eye, I appreciate a little green and blue is very nice observation.
also see the globular cluster NGC 6401, with the hyperion of 17 mm, the center is well appreciated and a light diffuse stain around, I see it normalito size but does not suggest much in sight with the eye of 17 mm. With the 17 mm Nagler can see up to stars within it, it shows better visual contrast. At the end I make a picture that I put in the blog:

Seguim with globular clusters , and in this case we see the NGC 6355, using the hyperion of 17 mm, has a size gradecito, and there is a triangle of stars next to it very nice, but is more diffuse than the last.
We then turn planetary nebula NGC 6572 is very nice to see with the hyperion of 17 mm, has a very distinctive asterism next, as a kind of house, in sight I see small, but in lateral view if you can see quite well, principle I see green, but as I watch, it seems rather celestite. With the eye of 9 mm (x170) the color if I see blue, it looks much better, and the view is prettier. I try now with the hyperion 5 mm (x300), trouble focusing, but eventually get it, here it looks blue, it is also more pronounced than the 9 mm.
We now see the open cluster NGC 6633, first use the 17 mm and is many ways that characterizes it, but do not see any star in particular that catches my attention. With the eye of 26 mm (X49), the cluster I see very open, and the vast majority of stars I see blue. I also see another open cluster is at hand, IC 4756, I still use the 26 mm eyepiece, and I see very open.
then go on to see the globular cluster NGC 6712 with the Meade 26 mm, the first impression I have I love, because I see it as a pretty big ball. The central area I see brighter. Step hyperion now use 17 mm, they begin to distinguish the stars and I love watching with the eye of 9 mm, the cluster greatly enhances the look like a cotton ball, it shows well the different densities cluster, as also observed with 12-mm Nagler, and the best view of the cluster, it is quite different from the stars, in addition to the different densities of the area that looks more like a nebula of this cluster.
then go on to observe the planetary nebula NGC 6781 with eyepiece of 17 mm. Nebula is a large and well defined, with the OIII filter is outlined very well the nebula and the eye of 17 mm, la veo mucho más bonita. Con el nagler de 17 mm y el NPB, la nebulosa se resalta pero no tanto como usando el OIII y el hyperion de 17 mm, para esta nebulosa es mejor usar el OIII que el filtro NPB que tiene Javi Jare. Usando el filtro también le vemos algo de estructura a la nebulosa, hago un dibujo de ella donde pongo la estructura, y me llevo una sorpresa al enseñárselo a Javi Jare, porque sin decirnos nada, él también vio dicha estructura. Cuando veo fotos de ella en Internet, me llevo una alegría porque aparece dicha estructura, se trata de que una parte del borde es menos densa, y eso lo hemos podido ver en visual. Si uso el filtro UHC, no resalta tanto como usando el filtro OIII. Todas estas observaciones con filtro, siempre I do it with the hyperion of 17 mm. At the end I make a drawing, you can see this link:

then go on to see an open cluster, NGC 6819, using the hyperion of 17 mm, is very small and quite concentrated, although it is difficult to see. I also see the blinking nebula (Caldwell 15) to show to others, because I've seen it many times.
Finally, I take it is near the maximum of Persia, start watching about 2:15 this morning, we saw a lot that night and stayed until 5 am, where we picked up and because we had long trek back, I hope you liked it.
