The effect of extension tube on telephoto is limited. Extension tube is more effective for lenses of shorter focal length, e.g. 50mm.

I use a 52.5mm extension tube on my 180mm, occassionally with a 2x teleconvertor. Can take quite nice insect pics with a good working distance.;)

your depth of field is so shallow that it iwill be very difficult to control...you will probably need very very stable hand or a tripod
