Hello to all:
These images were acquired with the telescope of 84cms. of the National Observatrory, property of the UNAM. The astronomer in charge, Mr. Manuel Lopez, realised the photographies with a Marconi camera, cooled with liquid nitrogen, and soon I realised the processing of the images with software PixInsigth and Photoshop CS.
For me it was a great experience to work with a professional astronomer and a so great telescope.
The National Observatory is on the mountain of San Pedro Martir in Baja California, Mexico, and is one of the dark places but of the world, on 9100 feet of the level of the sea.
Hopefully they like the images.
