More images with the STL11000 camera
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.
M31. From Bonilla on
october 3th 2008, total exposure 2 h 40 m, LRGB filters with filter Idas LP2,
camera: STL11000M, telescope: FSQ106N.

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
STL 11000M camera. Total exposure 2.5 h.

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.
