Theres a lot of darkness around the edge (vignetting), what should I do?
A. First of all, you need to determine what “a lot” means. Some vignetting is normal and with some configurations unavoidable (see previous question here). However if what you see is a very small circle of the microscope’s image (like the diameter of a pencil) then there’s a problem. Usually this is caused by attaching the system to the wrong type of optical attachment on the microscope. Sometimes, even though the attachment will screw onto, or fit inside the microscope’s adapter, it may be the wrong adapter. It may have a lens or something in it that is preventing a proper image. Make sure the attachment port is one that is designed to work with one of the 5 microscope standards that comes in the Clearshot 600 kit (see list here). Also, if the Clearshot 600 adapter will not properly screw onto an attachment, or slip into an eyepiece tube port on the microscope, there is a problem. There is never a situation where it is okay to just sit the adapter on top of a hole in the microscope. I
