We are Joaquin (father) and Yago (son), amateur astronomers from Spain, with a particular interest in astrophotography. We obtained the Jupiter image at left on october/1999 from our backyard in Pozuelo de Alarcon (Spain), seven miles away from Madrid downtown, with our C-8 scope and our home-built Cookbook 245 CCD camera. During the following years, we have upgraded our equipment.

IC1396, the elephant trunk nebulla. Multi-filter image (R, G, B, Halpha and OIII). Obtained from Pozuelo (Halpha and OIII, October 2008) and from the Montes de Toledo (R, G and B, September 2009). A total of 13 and a half hours were exposed using a FSQ106 scope and a STL11000 CCD camera.
Image processing: First, a RGB image was obtained. Then, the H alpha image was used to enhance the red channel (lighten, 100%) and, to a lesser extent, the blue channel (15%). The OIII image was used to enhance both the blue (100%) and green (100%) channels. In addition, the RGBHalphaOIII composite was also enhanced (luminance, 40%) with the Halpha image. I tried to obtain a "natural" looking color image.

IC 1805 (heart nebula). From Pozuelo, 18 hours exposure through narrowband filters SII, H alpha and OIII. Camera STL11000, scope FSQ 106N.
Emission nebula IC1396, including the Elephant Trunk nebula. From Pozuelo, October-December 1009 ( FSQ106 scope and STL11000 camera). Total exposure 13 hours through narrowband SII, H alpha and OIII filters (employing the Hubble color palette).
Area of Perseus full of dark nebullae, between the nebulla IC 348 (up left, next to the star Omicron Persei) and reflection/emisión nebulla NGC 1333 (down right). Imaged from Bonilla (Cuenca) on October 25th 2008. Camera: STL11000M. Telescope: FSQ106N. Total exposure 3 h 45 min through L, R, G and B filters.

Veil nebulla, supernova remnant in Cygnus. 15 hours total exposure through narrow-band filters (SII, Halpha and OIII), using the FSQ 106 scope and STL11000M camera. Shot from Pozuelo (Madrid), august-september 2008. The colors were assigned differently on each image; from left to right and up-down (red-green-blue): Halpha-OIII-OIII, Halpha-SII-OIII, y SII-Halpha-OIII, respectively.
Lagoon and trifid
nebullae in Sagittarius. LRGB image from Bonilla using the FSQ 106 scope and

First light of the new STL11000 camera, from our new observatory in Pozuelo (10 Km from Madrid center). Eight and a half hours of accumulated exposure (multiple 30 min subexposures) through a 7 nm H alpha filter (Baader), using the FSQ106 astrograph. Ionized Hidrogen gas glows (H alpha: 656 nm), in the area of the Cone nebulla (NGC 2264). The field is 4 degrees wide.
