Description
ATIK 4000LE Monochrome - Professional monochrome CCD camera with 23mm sensor diagonal - 4 megapixels
Highest quality CCD camera with thermoelectric cooling. Ideal for astro imaging
ATIK 4000 monochrome CCD camera - 23mm diagonal
The English camera manufacturer Artemis and the well-known manufacturer of astronomical CCD cameras, ATIK, have joined efforts to create a new level of CCD cameras in the high end range at very attractive prices.

The ATIK 4000LE CCD camera uses the Kodak KAI 04022 sensor. This sensor combines a large diagonal (23mm, 16x16mm square), a high resolution (4 megapixels), a high sensitivity and above all an affordable price that makes it the ideal choice for this camera. The excellent linear resolution makes it ideal for telescopes with extremely sharp optics such as apochromatic refractors or optimized Newtonian reflectors.

The most important advantages of the ATIK 4000LE camera:

-- USB 2 - fast frame download times
-- single stage thermoelectric peltier cooling, adjustable for a fixed temperature. This allows for having the same conditions for all photos
-- compatible with all common softwares such as AstroArt, Maxim DL, CCD Soft, etc.
-- Only very few "hot pixels" and low noise even in moderate set temperatures around -10°
-- A high-efficiency desiccant is used to dry the air inside the sensor chamber, preventing internal condensation, while condensation on the outside of the camera is avoided with the use of heater elements which gently warm the window. The power supplied to this heater is controllable through software so that it can be adapted to the environmental conditions.

Hands-on Advice from Teleskop-Service

1.25" or 2" filters?

One of the most frequently asked questions concerning this camera is whether 2" filters are needed or whether 1.25" filters (that are much cheaper) are sufficient.

The Facts, in a Nutshell:
Sensor diameter ........................................................................................................................ 23mm
Distance from the sensor to the front of the T2 thread.................................................................... 17mm
Clear aperture of a typical 1.25" Filter .......................................................................................... 26mm

Use of an ATiK filter wheel for 1.25" filters

The filter wheel would be attached at the closest possible distance directly to the camera. The distance from the T2 thread ot the position of the filters inside the wheel is 13mm. As such the ATiK filter wheel is highly optimized for a low profile. There is a little reserve in this figure of the distance since you can choose the position of the camera on the T2 thread depending on which angular orientation of the camera you desire. This gives up to 5mm reserve.

The total distance from the sensor to the filter will be about 30mm. Assuming a telescope with a focal ratio of f/6 the 100% illuminated field at this distance is 25.5mm. This is just enough for the ATK4000 camera.

With a focal ratio of f/5 it is a little less ideal, but still acceptable if you sacrifice the option of rotating the camera but instead move it as close as possible to the filter.

Summary: Telescopes with f/6 or longer can be used with 1.25" filters. Telescopes with f/5 are OK for use with 1.25" filters with certain limitations. Faster telescopes than f/5 should not be used with 1.25" filters. In any event when using 1.25" filters it is particularly important to keep as little distance as possible between the camera and the filter. Optimized solutions such as the ATiK filter wheel or the TS filter drawer are clearly preferable over longer solutions.
