This combo works surprisingly well, and I like the versatility it offers. I have had several masks that were either lost in the middle of a session or broke because of cheap quality.For the past two years I’ve done most of my deep space astrophotography with an iOptron SkyGuider Pro, Nikon D750, and a Tamron 150-600mm lens. The mask is hiding under the lens cap and can be revealed by twisting off an additional metal cap. You will find sharp consistent edges even doing landscape or nature photography.
