1 Introduction
Congratulations on your purchase of an Atik Series 4 camera. This manual will
help you get the most out of your Atik camera: please take the time to read it
thoroughly, and you will be ready to discover new worlds.
Atik cameras provide exceptional value for money, superior performance and
unrivalled ease of use. Our cameras 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 it will be your trusted astro-
photography companion for a long time to come.
Repairs, servicing and upgrades are available through your local dealer or at
http://www.atik-cameras.com.
Please note that modifications to the camera and/or accessories which
are undertaken without the manufacturer’s written permission will void
the warranty, details of which are given at the back of this manual.
1.1 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 is
available on our website at http://www.atik-cameras.com.

3.1 Camera Parts
1. Mini USB port
2. 2.1mm centre-positive 12V DC input
3. Desiccant port
3.2 Sensor
The sensors available in the Atik series 4 cameras are listed below:
Black and White Colour
Atik 420 SONY ICX274AL SONY ICX274AQ
Atik 450 SONY ICX655ALA SONY ICX655AQA
Atik 428EX SONY ICX674ALG SONY ICX674AQG
Atik 460EX SONY ICX694ALG SONY ICX694AQG
Atik 490EX SONY ICX814ALG SONY ICX814AQG
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.

3.3 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.
3.4 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.
3.5 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.
3.6 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.Ahigher speed “preview”
mode is also present, providing roughly twice the speed.
3.7 Cooling
All Series 4 cameras have a robust, regulated cooling system, meaning that
the CCD is kept at the desired temperature throughout the observing 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, but 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.
3.8 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 interface and a screwdriver, take out the used tablet and replace
Desiccant port

it with a fresh one. Replace the port cover and tighten (no need to over-
tighten). Wait 24 hours before connecting the camera again.
- To recharge the desiccant, place the tablet in an electric oven at 200ºC
for a couple of hours. Take it from the oven, wait a few minutes for it to
cool down slightly, then put it back in the camera and wait 24 hours.
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)
