EquipmentTelescope: TEC-140 Camera: QSI-583 Mount: Skywatcher NEQ-6 Exposures: H-alpha: 6 x 1800s (3nm Astrodon) OIII: 9 x 1800s (3nm Astrodon) SII: 3 x 1800s (3nm Astrodon) RGB: 3 x (4 x 600 s Astrodon True RGB) Total exposure time: 11 hours
DescriptionNGC 7000 is also known as the North America Nebula with the so called Gulf of Mexico. In this area the Cygnus Wall can be found. This part is the Mexican and Middle American part of the Nebula. It’s one of the most interesting parts of the nebula because this is a region of active star formation. Very near to the Wall a dark area (the Gulf of Mexico) can be seen that consist mainly of cold gas and dust, the ingredients for new stars. The wall actually is an ionization front where UV light from young stars ionize the cold hydrogen gas and make it glow in its typical red color.

DescriptionThe stars of constellation Andromeda and the magnificent neighboring galaxy M31 rise above the highest peak of Mount Gongga. Enjoying the fame as" The King of Sichuan Mountains", Mount Gongga is the easternmost 7,000 metres (23,000 ft) peak in the world and the third highest peak outside of the Himalaya/Karakoram.

DescriptionThis image of NGC 4725 was made on 3 consecutive nights in the Eifel, Germany, partly from Neroth observatory. For the luminance I used all data, including the RGB. Finally I used 7,5 h of data. Exposure: Clear 24 x 10 min R 6 x 10 min G 9 x 10 min B 6 x 10 min Processing pixinsight and photoshop

Date2013 March 20th, about 19 h UT
EquipmentA 300 mm f/2.8 coupled to a Canon 5D Mark III camera.
DescriptionI have obtained this image of Panstarrs Comet (C/2011 L4) on March 20th, 2013, beginning of northern spring. It was difficult to place and coordinate my son Jokin with only 6 years old on a ladder, just 50 meters away considering also that he could not see the comet. For this image I used a 300 mm telephoto lens, so that the effect of perspective seems to look and try to reach the comet. The first quarter moon provides ambient lighting that illuminates the figure.

LocationThe High Tatras, Slovakia
Date17. March, 2013
EquipmentCamera Canon 5D Mark II, Lens EF70-200mm f/4LL, USM, Focal Length 70 mm, Shutter Speed 10 sec, Aperture f/5, ISO 3200.
DescriptionI went on Sunday, March 17, 2013 for one day trip from Bratislava to the High Tatras mountains (370 km by car one way) to observe and to photograph a comet PANSTARRS (C/2011 L4). The comet was easily visible by naked eye, head bright as a star of 1,5 st magnitude and tail long 2-3 degrees. I will return to the mountains again as soon as weather permits. I saw my first comet Arend-Roland in spring 1957 as a 7 years old boy under the High Tatras too.

DescriptionIC 1318 region. The bright star is gamma Cyg (Sadr) and the dark molecular cloud is LDN 899. The open cluster M29 is on the bottom right and NGC 6910 is on the top left. This is a "true color" narrow band filter image made according to the article in the December 2011 issue of Sky and Telescope, p. 70. Although less obvious than with the Hubble palette of color, the presence of OIII regions mixed with Ha and SII in the right bottom corner is clearly visible.
