On this page, I present some information about my Atik Infinity Colour* camera**. Possibly, this is useful for others who want to acquire this camera as well...
See also pages (Archive):
See the appendix for the data.
*) 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"...
**) Received used on November 25, 2017 (see Notes below); sold at the end of December 2022, and finally transferred on January 5, 2023.
Note: Over Christmas 2022, I sold my Atik Infinity camera (transferred on January 5, 2023). I therefore cannot report any further experiences with it here. |
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.
Note: Since this is a used camera, the package may not be in its original state...

The adapter cable can be screwed into the power connector of the Atik Infinity camera, whereas the original power cable cannot.

The Atik Infinity can be operated, from a purely technical point of view, at the Heritage 100P. 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). In the meantime, I gave my Heritage 100P away.

The Atik Infinity can be operated at the Skymax-102. But because of the long focal length of the Skymax-102 and its small aperture ratio (1300 mm, f/12.7), a focal reducer is advisable (see above). I did not test this combination and sold the Skymax-102 in the meantime. Here the camera is shown without a focal reducer!

The Atik Infinity can be operated at the Skymax-127. But because of the long focal length of the Skymax-127 and its small aperture ratio (1500 mm, f/11.8), a focal reducer is advisable (see above). I tested this combination with a 2 x TS focal reducer plus a 2.5 cm extension tube (nominally 3 x, but 2.31 x in practice). Here the camera is shown without a focal reducer!

The ASI224MC camera uses the Sony CCD sensor type Sony ICX825 (CCD) with a resolution of 1.4 MegaPixels, or 1392 x 1014 pixels (H/V). The pixel size is 6.45 µm (quadratic pixels). With this, all sizes are known to calculate the field of view of the camera at different telescope tubes!
On page Atik Infinity Colour Camera - Field of View, I make more comprehensive estimates of the field of view with my telescopes at that time. In the following, I simply use the Website astronomy.tools to determine the field of view of my current telescopes (as of April 2021) at the Atik Infinity:
Legend: Orange Custom Scope = eVscope; Yellow Custom Scope = PS 72/432
And here the same for the ZWO ASI224MC (it uses the same sensor as the eVscope):
Legend: Orange Custom Scope = eVscope; Red Custom Scope = PS 72/432
I summarize the results in the following table (I added the ASI294MC):
Field of View |
|||||||
Telescope | Reducer | Focal Length | Aperture | ASI224MC* | Atik Infinity* | ASI294MC | Remarks |
PS 72/432 | --- | 432 | 72 | 0.65° x 0.48° | 1.19° x 0.89° | 2.54° x 1.73° | The largest FOV |
C5 | --- | 1250 | 127 | 0.22° x 0.17° | 0.41° x 0.31° | 0.88° x 0.60° | FOV like C8 with reducer |
C5 | f/6.3 | 787.5 | 127 | 0.36° x 0.17° | 0.65° x 0.49° | 1.40° x 0.95° | FOV a little smaller as with TLAPO1027 |
C8* | --- | 2032 | 203 | 0.14° x 0.1° | 0.25° x 0.19° | 0.54° x 0.37° | The smallest FOV |
C8* | f/6.3 | 1280 | 203 | 0.22° x 0.16° | 0.4° x 0.3° | 0.86° x 0.58° | FOV like C5 |
TLAPO1027* | --- | 714 | 102 | 0.39° x 0.29° | 0.72° x 0.54° | 1.54° x 1.05° | FOV a little larger that for C5 with reducer |
eVscope* | --- | 450 | 114 | 0.61° x 0.46 | --- | --- | Same chip as ASI224 |
Roughly simplified, the fields of view of the Atik Infinity are almost twice
as large per dimension, that is, the image areas are almost four times as large
as those of the ASI224MC. Since the chips have roughly the same numbers of pixels,
this difference is mainly due to the different pixel sizes (3.75 versus 6.45 µm). And compared with the ASI294MC, the fields of view of the Atik Infinity are almost half
as large per dimension.

I visited (and documented) the following sky objects with the Atik Infinity camera:
See also page Atik Infinity Colour Camera - Photo Gallery for photos of the DSO.
Notes: On this page, I only show successful first photo attempts. On page First Experiences, I present all of my first attempts, whereas on page Gallery, I will collect and present the, in my opinion, best photos.

Note that these photos show the complete image and that the large versions are in original size. This is due to the fact that the sky objects are extended - even beyond the field of view.

As a "minimal info" I can pass on that I cannot directly use the
Atik Infinity camera at my Heritage 100P, because the camera does not come
into focus, that is, it delivers only blurry images. However, with a Barlow
lens or a focal length extender, the focus point can be moved
in the desired direction, namely outwards. Depending on the magnification
factor (1.5 x, 2 x or 3 x), the focal length is extended accordingly, which
might be quite an advantage. But this also reduces the aperture ratio, thus
requiring longer exposure times. The results achieved with the Heritage 100P
with a focal length extender can, however, only be called "poor"...
Update: I do no longer own the Heritage 100P.
The camera can be used directly at the Explorer 150PDS, and the achieved
results are also much better than those achieved with the Heritage 100P. With
appropriate post-processing, they seem to be no longer far away from what can
be achieved with my equipment - they are also, at least in part, comparable
to those of the eVscope.
Update: I do no longer own the Explorer 150PDS.
Now it is all about detail improvements and
trying out the camera with other telescopes. I tested the camera already briefly
with the Skymax-127 and a 2 x focal reducer plus extension tube. Further tests
are needed, als well as tests with the Skymax-102.
Update: I do no longer own the Skymax-102 and Skymax-127. I also decided not to use the camera at my Maks. Later, I used the camera at my C8 and C5 instead.
Even with the initial poor results, I was already able to "see" more objects with the camera than I was previously able to find purely visually. In that sense, I was already satisfied with the camera from the beginning.
In the end, the photos were not really satisfying for me, except for those of the Orion Nebula M 42. Maybe, the camera needs longer exposure times than an AZ mount allows.
I would also like to point out a few more positive aspects of "quick-and-dirty astronomy photography," which apply to "sub-optimal" photos in general, as well. 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 often 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.
Note: Over Christmas 2022, I sold my Atik Infinity camera (transferred on January 5, 2023). I therefore cannot report any further experiences with it here. |
