I have gained this glass primarily for observations of the sky. Unfortunately have no comparison to glasses upmarket, but in my opinion the part is really worth the money. Super visual field and for me the picture is perfectly okay. On vacation I have used the glass for observation of nature. It has also given me a lot of joy. To Macke: The glass is a plastic holder for mounting in on a photo tripod. This holder is simply rubbish! The part vibrates with every touch of forever, so that at least in the sky nothing more sensible. Here was unfortunately once again saved at the wrong end. I have copied my part made of aluminum. With this holder assembly is then fine. But this opportunity just has not any.
