On this page, I present some information about my Atik Infinity Colour* camera (received used on November 25, 2017). Up to now, I was regrettably not able to use it...

Notes

The Atik Infinity Colour camera is originally sold with the following accessories:

I bought the camera used at Teleskop-Leasing, instead of leasing it at first. They also supplied an adapter cable for the power supply that can be screwed into the camera und thus prevents the power cable from being removed inadvertently. This was a frequent source of criticism that I read on the Internet. I hope that the adapter will help prevent power interruptions.

The basic data was taken from the Atik Website.

*) Usually, I would write "Color", because I try to use American English, but Atik is a company located in the UK, and therefore it's "Colour"...

Adapter Cable for the Power Cable

The adapter cable can be screwed into the power connector of the Atik Infinity camera, whereas the original power cable cannot. The plug of the original power cable sits fairly loose in the power connnector and can easily be removed inadvertently.

Teleskop-Leasing added the adapter cable to the package to fight one often stated criticism, namely that the power cable gets loose when the camera is moved by the mount and thus, the recording is interrupted. I do not understand with Atik cannot deliver the camera with a "screw in" power cable. That's probably a matter of pennies...

Because of the length of the plug of the power supply cable, the plug sits firmly in the mating connector of the adapter cable. Here you do not have to worry that the connection gets loose easily.

Heritage 100P on Star Discovery AZ GoTo Mount

The Atik Infinity can be operated, from a purely technical point of view, at the Heritage 100P. But unfortunately, this combination does not work as such, because I cannot get into focus with the camera. But with a Barlow lens or a focal extender this is possible (tested with 2 x versions; not shown).

First Photo Attempts

First Attempts

The following very first photos with the Atik Infinity camera were taken with the Heritage 100P on the Star Discovery GoTo mount (Nov 29, 2017). It turned out that unfortunately I was not able to get into focus with this telescope.

Visited Sky Objects

So far, I have visited (and documented...) the following sky objects with the Atik Infinity:

 

Preliminary Conclusions

In progress

As a "first information," I can already pass on that I cannot use the Atik Infinity camera on the Heritage 100P as such, because the camera does not come into focus, that is, delivers only blurry images. Meanwhile, I found out that using a Barlow lens* might be an option, because it moves the focus point in the desired direction, namely outward. Depending on the magnification factor (1.5 x or 2 x), the focal length is extended, which might be quite advantageous, but also reduces the aperture ratio, which would require longer exposure times. A first test confirmed this, but also revealed that the sky objects appear much fainter, even if you increase the exposure time.

The results that I have achieved so far with the Atik Infinity camera are certainly way inferior to what can be achieved with it. Nevertheless, I have already seen more with it than I was able to find so far when observing purely visually. In this sense I am satisfied with the camera. And "room for improvement " is also nice, because this way I still have goals for the future...

Now, I would like to point out a few more positive aspects of "quick-and-dirty astronomy photography," which also apply to "sub-optimal" photos. Firstly, I can "see" objects with the camera, which I am not able to find for a number of reasons when observing visually. Even though the telescope tube was sitting on the GoTo mount, I was not able to find some of the objects when observing visually, assuming that the objects were (mostly) correctly accessed. Thus, the camera can lead to the feeling of small successes, instead of frustration and disappointment. Secondly, I can use the camera to save an image of the observed sky object, which at least, helps me afterwards to identify it, in the case that I am not quite sure that I actually have found it. And the image also shows certain object features that I normally cannot remember and quickly forget after observing. Later, you can find something like "a faint glow" or "nice" in my notes, which tells you close to nothing. Even a tiny and blurry photo contains more information that I can use in my recordings than such "overall" remarks.

I made another interesting discovery regarding the photos of the Atik Infinity, but I have to mke a detour first. For telescopes, there is a maximum beneficial magnification, which should not be exceeded, because above this magnification, no further details become visible - the image is just "blown up " (besides, often the moderate sky quality does not allow using higher magnifications...). So you normally should not exceed this magnification. But as always, there is no rule without exception! Stoyan recommends for smaller extended objects to go up to twice the maximum beneficial magnification for a secure detection of sky objects (this is what he calls "maximum magnification"). In simple terms, I would put it this way: Often a certain size is needed to recognize objects well, details play a lesser role.

What does this have to do with the Atik Infinity camera? Well, I found that on images in 1:1 format or even smaller, faint objects, despite the higher sharpness, are more difficult to recognize than on larger, "blown up" versions of the same image (or as the Atik Infinity application on my laptop presented), which actually provide no further information. Obviously, a certain image size is needed to recognite faint objects well.

*) So far, I have always found only the opposite, namely, that Schmidt-Cassegrain telescopes (e.g. a Celestron C8, C9, or C11) were provided with a focal reducer to shorten the long focal length of these telescopes and to reduce the opening ratio, that is, to increase the light sensitivity. The reasons for this approach are unknown to me, because a fast Newton would do that as well, but presumably, the optical power and light collection performance of the Schmidt-Cassegrain tubes are better. Or they just do this, because they already own the Schmidt-Cassegrain tube?
