Excellant orthoscopic view with great eye relief. There is a ghost image on very bright planetary images, but galaxies and nebulae are impressive. Ghost is not apparent if object is closely centered. Only 60* FOV but excellant views if tracking. Sharp and contrasty!! Good value at the price. Same for the 12mm !!!
