OMEA ALL SKY CAMERA
Warning : in all cases, the camera needs a PC and dedicated software (provided) to transfert data into it, a small PC like  ZOTAC is sufficient to operate the camera : documentation can be downloaded here
Specifications :
ALU housing camera version  (all outer camera parts are made of anodized aluminium)
Alcor-system (2013)

 
- detector is less sensitive and image might be noisier, please check out this page to compare monochrome and color camera performances of operating camera.
Monochrome / color : color version produces more realistic images of the sky, but :
All parts are made of anodized aluminium, water tight by o'rings seals, automatic dome heater located at dome's base allow to warm up the acrylic dome in order to remove frost and icing, to preserve good image quality.
Water tight connectors, also allowing a quick camera removal with no wires attached to it.
Auto-iris option :
- auto-iris allows camera to record daylight images (otherwise image is saturated and no image can be achieved because of lens aperture, even using 100s exposure time and lowest gain)
- Auto-iris is mandatory for color camera, otherwise CCD color bayer pattern filter will be definitively damaged by Sun course in the sky

• 1.3M : One point three millions pixels camera
• 2.0M :
Two millions pixels camera, those are smaller but camera is more sensitive than 1.3M cameras

• X code : set to H if dome heater is requested, set to F if no dome heater is requested
• Y code : set to C if color sensor is requested, set to M if monochrome sensor is requested
• Z code : set to A if auto-iris is requested, set to N if no auto-iris is requested.
For instance OMEA-1.3M-HMN means 1.3 millions pixel camera, dome heater option, monochrome sensor and no auto-iris.

Warning : camera with color sensor and no auto-iris cannot be ordered, like OMEA-1.3M-XCN or like  OMEA-2.0M -XCN, because during day, image of the Sun and its sidereal path on the CCD tends to fade away Bayer color filter array, and image color sensor is damaged forever.
Some hints to help you to decide which version you could order
Price :
OMEA 1.3M color, with high altitude clouds reflecting light pollution (65sec exposure, click image to enlarge) marker shows telescope position
Color camera is perfectly showing the impact of light pollution. Color camera is ideal for showing atmospheric events like polar aurora, blue jets, "sprites" or "elves".
Color camera allows perfect imaging during day, with auto-iris embedded inside the lens. Aiming directly to the SUN, it does not prevent from recording images.
OMEA camera can capture very fast  events like a meteor entering Earth's atmosphere, leaving a remnant of its path (see below).
Prices are only provided for information purposes, not all configurations can be provided here, in any case contact us for a quote because prices are subject to change according to exchange rates of subparts needed to build the camera. Control software is included in this price. The less amount of options selected, the cheaper the price will be.
