If you had access to a monolithic first-rate - scope , you could create to - die - for scene of other galaxy , ripe ? Maybe … but actually , it ’s harder than you ’d think . The European Southern Observatory offered amateur astronomers the chance to turn its wealth of data into images , and here are some termination .
The succeeder of ESO ’s “ Hidden Treasures ” contest , Igor Chekalin , gets a free misstep to Chile to visit the ESO ’s Very big Telescope . And runners up get swag like an iPod touch , a “ laser cube ” manikin of the VLT , and some other goody . To win these prize , the amateur had to dig through the ESO ’s mountains of data and figure out how to symbolise it as image .
accord tothe ESO press release :
The motion-picture show of the Universe that can be seen in ESO ’s releases are telling . However , many time of day of skilful body of work are required to assemble the raw greyscale data enamor by the telescopes into these colourful simulacrum , correcting them for distortions and unwanted signatures of the instrument , and enhance them so as to bring out the details contained in the astronomical information . ESO has a team of professional image C.P.U. , but for the ESO ’s Hidden Treasures 2010 competition , the expert adjudicate to give astronomy and picture taking partizan the opportunity to show the earthly concern what they could do with the mammoth amount of data contained in ESO ’s archives .
Here are some of our pet , among the 20 victor . you could see more via the link . [ ESO ]
NGC1850 EMMI bySergey Stepanenko .
A colour image is composed of :
R – hour angle filter , 1x 1548second exp.time
grand – SII filter , 1x 1800 second exp.time
B – NII filter , 1x 1800 arcsecond exp.time
M78 nebular complex in Orion , byIgor Chekalin .
Image was calibrated , and Stacked from RAW data via IRAF software , composed/ white - balanced in Iris , and post - processed in PhotoShop .

SII filter ( 6×950 mo ) – BLUE communication channel
Ha+SII ( 50/50)- GREEN line
NGC 3621 byJoseph DePasquale .
Around 22 million swooning years aside , in the constellation of Hydra .
This image is comprised of datum taken on the ESO WFI instrument .
4x300s bacillus
4x300s quintuplet
4x300s R
4x300s Halpha
Dust of Orion Nebula ( ESO 2.2 m telescope ) byIgor Chekalin .
R = HAlpha – Continum
G = Continum
B = Continum – Halpha * 0.05
Celestial Prominences NGC3582 byJoseph DePasquale .
The NGC 3582 nebula sit inside of the star forming region call RCW 57 . The massive loops of ionized gas expelled by dying stars cue me of solar bump . This figure is comprised of data taken on the 2.2 yard scope at La Silla with the WFI instrument on June 16 , 2002 . have only 2 channels of datum to work with inspire some non - traditional color employment .
7 x 5 Fukkianese with H - alpha filter
4 x 30 s with Broadband Rc filter
effigy was de - biased and plane fielded using IRAF with the esowfi tool . television channel were combined using PixInsight as :
red = halpha
green = 0.25halpha + 0.75Rc
blue = Rc
Combined channels were further processed in Photoshop to remove instrumental artifacts and tweak color and craw .
Antennae Galaxies byAlberto Milani .
feeler Galaxies
aerial Galaxies – NGC 4038 / NGC 4039
Based on observations made with the European Southern Observatory scope incur from the ESO / ST - ECF Science Archive Facility .
tool : FORS1
Filters : R_BESS , V_BESS , B_BESS , H_Alpha , HeII
Aquisition date stamp : 2005 - 06 - 09 and 2005 - 08 - 07/08
Calibrated for preconception and flat field with IRAF , process with GIMP to combine colors and to heighten level , contrast , saturation and other stuff .
Sakurai ’s Object byJoshua ( Josh ) Barrington .
This image heighten Sakurai ’s object . Data obtained using FORS2 instrument by ESO . The star playing field is pick out through R , five and B filters .
The house of cards is taken using the H filter .
Processing was done with FITS Liberator and GIMP .
