In 2020, I used the Atik Infinity camera again after a long break (in 2019 I did not use it at all), and this was at the C8. In February, I used reducers for this, in December none (direct connection of the camera to the 1.25" visual back). Prior to these observations, I did "dry runs" to see with which equipment I would get into focus with the Atik Infinity. See page Atik Infinity Colour Camera - Further Experiences for details on the dry runs and observations.
In contrast to the first two years 2017 and 2018, I present the photos, except in galleries, only directly on the detail pages for the sky objects. So there are no more pages for single "observation days" in order to keep the effort a bit lower.
I looked into different sky regions, so a description does not make much sense here.
Since the observations are separated through a long period of time, a sky map does not make much sense.
The observations started every day when it was sufficiently dark.
All observations were conducted in Mühlhausen/Kraichgau (Germany):
Of course, the Atik Infinity camera is needed for taking photos. To operate the camera, a laptop on which the control application runs is also required. Depending on the telescope tube used, focal length extenders (Barlow lens, focal extender) or reducers must also be used. This is indicated for the respective observations.
Atik Infinity connected via f/6.3 reducer/corrector and 1,25" visual back to C8
In addition, the telescope tube has always to be mounted on my Star Discovery GoTo mount because sky objects need to be tracked when being observed and photographed with a camera. And last but not least, you need a 12 V power supply for the camera and GoTo mount (and possibly one for the laptop).
I acquired this tube (2032 mm, f/10) at the end of 2019. On this tube, the camera gets into focus when using focal length reducers, but also completely without reducers. Celestron's f/6.3 reducer/corrector was specifically designed for this tube (and similar ones). In February, I also coupled this reducer with a 0.5 x reducer from TS-Optics (no longer in my possession), while in December I observed completely without reducer.
In general, the sky above Mühlhausen/Kraichgau is "light-polluted" and does not invite you to search for deep sky objects. Cameras will find the objects even in worse conditions, but really good results are obtained only under dark skies.

The Infinity software got often stuck and had to be restarted.

The Infinity software made it hard for me to center objects in the image field, because the image was often not updated in live view mode.

When searching for deep sky objects, a good preparation is obligatory - you read this, and I can confirm it. "Good preparation" means, on the one hand, that you compile a list of objects that you want to observe, including notes on where and how to find them.
On the other hand, even when doing "quick astro photography" with the Atik Infinity camera (a variety of "video astronomy") more technology has to be prepared than for purely visual observation, especially if you just put a small Dobson or Maksutov telescope on the terrace table for this... Above, I describe, what equipment I use and need for taking photos with the Atik Infinity camera.
