AST8300-B-M-FW
The AST8300-B is based on 8-megapixels Monochrome KAF-8300 CCD Sensor and is equipped with integrated 7 position Filter-Wheel.
The AST8300-B Features
- New concept low-vacuum CCD sensor chamber that guarantees no-frost with -42°C DeltaT at only 2.4A of power consumption
- Total Noise of 6.5e- rms using low-noise acquisition mode
- Powerful 1GHz microprocessor for stand alone wire-free operation (no PC is needed)
- PC like use with operating system, graphic desktop, web access, applications that can be created, installed and removed
- 5.4 um pixel size
- Optional 5" 800x480 touchscreen full color display (removable)
- Integrated Gbit Ethernet and WiFi connection to PC / Tablet / Smartphone
- 8 GB (expandable up to 32 GB) internal storage plus external USB thumb drive or hard-disk
- 2 HS USB, TX/RX serial port, I2C, SPI, +3.3V, +5V, +12V DC output power supplies
- User configurable I/O lines to implement triggers, alarms, custom interfaces
SmartCamera Approach
The Astrel Instruments cameras are powered by a 1000MHz Processor with 1Gb of memory and up to 32Gb of on-board storage.
The camera can autonomously autoguide with many commercial USB autoguider cameras and use planetarium applications to control the mount operations (alignment, goto, etc) on most commercial mounts. Many other commercial devices like motorized focusers, external filter wheels, can also be directly connected and managed autonomously by the camera.
Integrated Filter Wheel
Astrel cameras with integrated filter-wheel can be fit with filters directly during camera assembly. We can directly buy and mount the filters selected by the customer.
Cooling and Vacuum Chamber
The sensor and the cooling chain are contained in a vacuum proof chamber: using the included vacuum pump connected to the valve on the rear of the camera body, in less than a minute the air can be pumped-out. This has 2 fundamental effects: it eliminates the possibility of frost forming inside the chamber and minimizes the convention up and down heat transfer inside the chamber, optimizing the heat removal via the cold finger and avoiding cooling of the optical window that could lead to fogging.
The base package includes
- Suitcase filled with protective foam for the camera and its accessories
- AST8300-B camera body
- Vacuum pump with incorporated pressure gauge, tube and joint
- Ethernet cable
- Battery power cable: power cable extension with car lighter plug
