Trying to get perfectly sharp focus on a telescope and camera is not easy. Unlike older film 35mm cameras, there seems to be no ground glass center for ultrasharp focus,
Here I used unsharp mask in GIMP:
I also did some eyepiece projection (using the 1.25" camera adapter) to increase magnification. This is with the 25mm eyepiece; ISO 100; 1/20th.
Eyepiece projection is hard. Getting sharp focus is even harder; exposures get longer; more opportunity for wind to move the scope during exposure. Sometimes everything comes together. Prime focus; 1/160th; ISO 100:
