This is my second try at the comet C/2023 H2 Lemmon. It turned out better than last time, but it's still not as bright as I had hoped. The reason the stars appear as slashes is because I was tracking at the speed of the comet, not the stars. The head of the thing seems nice and bright, but I still can't bring out a tail.

Takahashi 106 scope, Nikon D810A camera, Astro-Physics Mach2 GTO tracking mount. I used a tool in the mount software called Horizons. It allows you to load an ephemeris from the JPL Horizons website and use it to track the comet.

Very little. I stretched it a bit and ran a noise elimination software.
