Hi Vasili, thanks for your message. If you are using the CPC 11 in alt/az mode with no guiding just tracking your setup would be similar to mine, it has limitations but can give good results.
When setting up the scope make sure it is level and aligned very well this will help in getting the scope to track the object well.
Use a focal reducer I use a f6.3 reducer and spend some time getting the focus at its best I use a bahtinov mask.
For alt/az no guiding photography you need to use short exposures and high iso I use 25 second exposures at iso 1600 and try to take between 200 and 400 subs, also take 50 dark and 50 bias frames and stack them in DeepSkyStacker or similar software. The resulting stacked image will still have some elongated stars from field rotation at the edges of the frame but should be OK at the centre, just crop the edges then you can process the image in Photoshop, Gimp, Star tools or similar software I use Gimp and Star tools.
It can take some time to master the art of alt/az no guiding Astrophotogaphy, I have found that learning good image processing skills is a great help.
I hope this helps a little and I know others will comment and help, keep looking at the information in this site.
You can see some of my alt/az no guiding images and information about settings at my astrobin gallery, just click on the link in my signature below.
