I have had my TLS-800 for quite a long time. However, I am reluctant to use it due to the vibration caused by the DSLR camera, not easy to get a sharp image by using it.
Today, I try it out again with the installation of my new long plate (25cm) to support the scope. It is obvious from the shots that the vibration created was reduced significantly with the use of long plate.
The following test shots were taken at ISO 320 (1/160s) and ISO 500 (1/100s) for the road sign and the sparrow respectively. No shutter cord, mirror lock, etc. was applied in the shots.
Place you left hand and apply downward force slightly on the front portion of your scope while your right hand hold your camera during exposure is a very efficient method to reduce the vibration, this is the skill of handling ultra-long lenses.
The setup,
