OMEGON F/4 ASTROGRAPH: FOR UNFORGETTABLE ASTRONOMIC PHOTOGRAPHS
WHICH TELESCOPE GUARANTEES GREAT PHOTOS WITH THE LESS EFFORT POSSIBLE? COMPARED TO COMMON TELESCOPES, THE OMEGON ASTROGRAPH MAKES EVERYTHING EASIER. WHY? THE ANSWER IS OBVIOUS: WITH AN F/4 FOCAL RATIO, EXPOSURE TIMES ARE SHORT AND BRIGHT AT THE SAME TIME. DIVE INTO THE WORLD OF DEEP-SKY PHOTOGRAPHY AND WATCH THE DIM GALAXIES OR THE COUNTLESS DETAILS OF EMISSION NEBULAE. THE OMEGON ASTROGRAPH SETS A NEW STANDARD IN ASTROPHOTOGRAPHY…

THE ADVANTAGES AT A GLANCE:

F/4 ASTROGRAPH: ULTRA-FAST FALSE RATIO TELESCOPE FOR SHORT EXPOSURE TIMES
THANKS TO THE SHORT STRUCTURE IT IS ALSO SUITABLE FOR MEDIUM SIZE FRAMES
WIDE FIELD OF VIEW FOR EXTENDED OBJECTS: APPROXIMATELY 24MM OF ILLUMINATION
PARABOLIC PRIMARY MIRROR, 94% REFLECTIVE TREATMENT FOR BRIGHT IMAGES
LARGE SECONDARY MIRROR: GREAT LIGHTING FOR DSLR CAMERAS
CRAYFORD 2" FOCUSER WITH 1:10 GEAR AND 1.25" REDUCER
FASTER COOLING FOR FASTER OBSERVING: PRIMARY MIRROR FAN
F/4 PRIMARY MIRROR WITH 94% REFLECTIVITY
ASTROGRAPHS ARE SUITABLE FOR VISUAL OBSERVING BUT THEY SHOW THEIR TRUE POTENTIAL IN ASTROPHOTOGRAPHY. WITH A FOCAL RATIO OF F/4 THESE INSTRUMENTS ARE ONE OF THE "FASTEST" NEWTONIAN TELESCOPES, IDEAL FOR SHORT EXPOSURE PHOTOGRAPHS.

THE SECONDARY MIRROR AND THE BK7 PARABOLIC PRIMARY MIRROR ARE EQUIPPED WITH 94% REFLECTIVE TREATMENT, THUS OFFERING BRIGHT, CONTRAST-RICH IMAGES. COMPARED TO A "NORMAL" TREATMENT AT 88%, THE DIFFERENCE IS SENSIBLE.

NO SHADING - ONLY LIGHT: LARGE SECONDARY MIRROR
PLACE YOUR DSLR OR MODERN CCD CAMERA ONTO THE TELESCOPE AND SEE THE IMPRESSIVE ILLUMINATION ACROSS THE WIDE FIELD OF VIEW. THANKS TO THE PARTICULARLY LARGE SECONDARY MIRROR (SEE ALSO BELOW) NO SHADING OF ANY TYPE IS DETECTED. SO, EVEN OBSERVING WITH A 2" PANORAMIC EYEPIECE IS A blast.

LESS ABERRATIONS - MORE SATISFACTION WITH THE PICTURE
THIS TELESCOPE IS COMPACT, THANKS TO ITS STRUCTURE AND PARTICULARLY SHORT FOCUS. IN FACT, COMPARED TO AN F/5 OPTIC, THE ASTROGRAPH IS ABOUT 20% SHORTER. THIS MEANS BEING ABLE TO USE THE TUBE EVEN WITH MEDIUM-SIZE FRAMES; THEREFORE SAVE ON THE COST OF LARGE AND HEAVY FRAMES, AND CONCENTRATE ON THE QUALITY OF THE OPTICS.

AN ADDITIONAL BENEFIT: THE SHORT FOCUS MAKES THE ASTROGRAPH THE PERFECT INSTRUMENT FOR OBSERVING EXTENDED DEEP-SKY OBJECTS. ALSO, THESE OPTICS ARE MORE TOLERANT TO SMALL TRACKING ERRORS THAN A LONGER FOCUS TELESCOPE. WITH A MINIMUM EFFORT YOU WILL THEREFORE GET UNFORGETTABLE ASTRONOMICAL IMAGES.

CRAYFORD 2" FOCUSER WITH 1:10 GEAR

WITH THE OMEGON V-POWER FOCUSER YOU WILL HAVE PERFECT FOCUS ON ANY CELESTIAL OBJECT. THE 1:10 GEARBOX, ROBUST BEARINGS AND THE GUIDE RAIL MAKE THIS INSTRUMENT STABLE AND COMFORTABLE TO USE. THANKS TO THE OPTIMIZED DESIGN, THE FOCUSER FIRMLY HOLDS CAMERAS OF UP TO 5 KILOGRAMS, WITHOUT MOVING.

EXTREMELY PRECISE: THE FOCUSER MOVES SMOOTHLY AND PRECISE THANKS TO THE STAINLESS STEEL BEARINGS AND RAIL
HEAVY DUTY CAMERA AND EYEPIECE HOLDER: NO OSCILLATION UP TO 5 KG
SCALE 1:10 FOR PRECISE FOCUS, WITH GRADUATED SCALE
ANTI-REFLECTIVE GROOVES FOR HIGH CONTRAST
2" WITH REDUCTION TO 1.25"
OBSERVATIONS FASTER: FAN FOR THE PRIMARY MIRROR
JUST A QUIET BUZZ, BUT A GREAT EFFECT: THE BUILT-IN 12V FAN COOLS YOUR MAIN MIRROR UP TO 50% FASTER. THIS WAY YOUR TELESCOPE REACHES THE OPTIMAL IMAGE QUALITY QUICKER. WITHOUT MAKING YOU WAIT.
