Looks good. I can see M41 and Rossette nebula. I tried to zoom in and then noticed star trails. You need tracking or shorter exposure with maybe higher ISO if camera allows.

If you are using the 500 rule it will tell you 21 sec for this camera, lens, f stop & declination combination. However it is not as accurate with newer cameras and I suggest you use the NPF rule which indicates 5.97 sec. maximum exposure around 0 deg. declination. I use PhotoPills to give me the maximum exposure length, both 500 rule and NPF.

If camera allows try 6 sec at 25,000 ISO. I just looked up the specs for the camera, WOW! Enjoy!
