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.

3" FOCUSER WITH LINEAR BALL BEARING: ILLUMINATE WIDE FIELDS OF VIEW

INSTEAD OF A CLASSIC BALL BEARING, THIS FOCUSER IS EQUIPPED WITH A "LINEAR POWER SYSTEM". WHAT IS THE BENEFIT? A STAINLESS STEEL RAIL THAT MAKES IT MUCH MORE STABLE: THE FOCUSER WILL NO LONGER WUCK OR SLIP.

THE 72MM INNER DIAMETER OF THE TUBE PROVIDES SHADOW-FREE ILLUMINATION FOR LARGE, BRIGHT SPECIFICS. EVEN FITS FOR LARGE FORMAT SENSORS. THE RIGHT FOCUSER FOR YOUR CAMERA WITH A WIDE FIELD OF VIEW.

ON THE OTHER HAND, A 2" FOCUSER COULD SHOW UNPLEASANT SHADOWS AT THE EDGES OF THE IMAGE WHILE A 3" GUARANTEES MORE FREEDOM, FOR LARGE AND EXTENDED IMAGES. JUST AS IT SHOULD BE!

OF COURSE THIS FOCUSER IS MUCH MORE

THE 1:10 DUAL RATE SPROCKET HELPS YOU PRECISE FOCUS ON CELESTIAL OBJECTS. - A REDUCER FROM 2" TO 1.25": FOR ALL EYEPIECES AND ADAPTERS
AN ENGRAVED SCALE, TO ALWAYS FIND THE FOCUS POSITION
ONLY 82MM IN HEIGHT AND AN ADJUSTMENT RANGE OF 50MM
74X0,5 MM FITTING FOR ADAPTER OR FILTER WHEEL
CLUTCH ADJUSTMENT
HEIGHT 82MM
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.
