There is an old trick for astrophotography, especially for longer exposures. Assuming the setup is on a nice stable tripod or telescope mount and focused properly, set the camera to bulb and trigger the shutter with the lens cap on. Then, carefully remove the lens cap, keeping it over the front of the lens for a few seconds to allow vibrations to dampen. Then whisk the cap away and time the exposure. Whisk the cap back in front of the lens, and then attach firmly. Then allow the shutter to close. This way, and vibrations from the mirror or shutter are eliminated. Crude, but effective.

Keep experimenting.
