Buena calidad y función

I contacted Celestron to see if this fit my AZ100 Lunar Edition sold only at Costco (received as a gift) and they responded that it would not, but I checked the dimensions and it seemed to be a little big (1/8"). It was on sale so I thought I would give it a try and it fit just fine. You need to remove the plastic shade cover on the big end by just pulling it straight off to reveal the grove in the end of the telescope where the set screws go and screw them all the way in and there you go you can look at the sun and see the black sunspots move! It does have an orangish tint, but you don't notice it when you're looking at the sun.

Worked perfectly on my 5” reflector telescope.

Protection against solar viewing. The straps provide added protection.

Ever seen sun spots? Very awesome lense.

Works good. You can see sun spots just wish you could see solar flares.

I looked at the sun, it was cool. It works well and it's nice having the safety straps to protect the optics of your telescope and your face

Works great for viewing sun spots and eclipses!
