The most important thing when taking pictures is of course keeping the camera still. When I take close up shots of parts and such I always use a tripod, under magnification the camera needs to be rock steady. The times I can't use a mount of any kind I take at least four of each picture, and even then there may not be one that is clear because I moved a touch. If you can keep it steady it will make up for a lot of bad lighting. Keep trying!
