ATIK CAMERA 4120EX Series 4 Color Camera

Introduction

Congratulations on your purchase of an Atik Series 4 Camera. This manual will help you get the most out of your Atik camera so please take the time to read it thoroughly and you’ll soon be ready to discover new worlds.

Atik Cameras provide exceptional value for money, superior performance and unparalleled ease of use. They are the result of extensive research and development, each one having been designed and built with the requirements of the most demanding astro imager in mind. Your Atik camera incorporates state- of-the-art design and materials, and will be your trusted astrophotography companion for a long time to come.

Further information

For installation instructions and other useful information please refer to the Quickstart guide which was shipped with the camera. Information on the software is given in the ArtemisCapture guide, a PDF file of which is copied to your computer hard drive by the software installer. Further information, including a number of ‘Getting Started’ tutorial videos, is available on our website at http://www.atik-cameras.com

Due to the very clean nature of these CCDs, dark frames are unnecessary in most cases.
This is due to the low noise which stands at an amazing 5 electrons RMS typical.

Optical Window
The optical window used in front of the CCD is a BK7 with BBAR coatings on both sides ensuring that no reflection will appear in your image.

Analog to Digital Converter (ADC)
The Analog to Digital Converter (ADC) is a 16-bit ADC. This means that your Atik camera will allow you to record subtle levels of gray, providing you with enhanced dynamic range when capturing an image.

Power Consumption
Your Atik camera was designed to have low power consumption: please see the table in section 4 for details specific to your camera model. The 2.1mm centre-positive DC input is compatible with a wide range of 12V DC supplies.

WARNING: If you have purchased the optional mains power adaptor, please note that it is for indoor or observatory use only. There is a risk of electric shock if the adaptor is used in damp environments or outside. If in doubt, do not use the adaptor and consult a trained electrician.

USB Port
The Atik Series 4 cameras use a USB 2.0 high-speed interface, allowing full- frame image downloads in only a few seconds. A higher speed “preview” mode is also present, which provides roughly twice the speed.

Cooling
All Series 4 cameras have a robust, regulated cooling system, meaning that the CCD is kept at the desired temperature throughout the imaging session. The very low readout noise, combined with efficient cooling, means that dark frames are not necessary in most situations, allowing you to spend more time imaging and less time taking calibration frames. If very long exposures are to be used or high precision data is required (exo-planet searches, for example), dark frame libraries will be easy to maintain.

The cooling delta varies between models and full specifications are available in the Technical Information Summary on page 7. Please note: the cooling delta is how far below the ambient temperature the camera can achieve, rather than a fixed temperature it will cool to.
After switching on the camera, it is advisable to allow up to 5 minutes before taking images in order to allow the temperature to stablilize.

Replacing the desiccant
Your camera includes a high-performance molecular sieve desiccant tablet which is used to avoid condensation in the CCD chamber. Although this desiccant will last a long time it may eventually need replacement or recharging, in which case please follow the instructions below:

To replace the desiccant, open the desiccant port with the supplied plastic tool and a screwdriver and take out the used tablet.
To recharge the desiccant, place the tablet in an electric oven at 200ºC for 2 hours. Take the tablet out the oven (CAUTION: tablet will be very hot) and allow it to cool down.
Place the recharged tablet back in the camera, replace the port cover and tighten (no need to over-tighten). Wait 24 hours before connecting the camera again.

You will notice that there is a filter inside the desiccant chamber. The purpose of this is to avoid contamination of the chamber when the desiccant is being replaced. The filter is very fragile and should not be touched.

The following table gives the angular resolution per pixel with certain focal distances. The formula to calculate any other focal length is:
(Pixel Size (μm) / Focal Distance (mm)) * 206.3 = angular resolution (arcseconds/pixel)
