This accessory is needed when shooting images through the Celestron Nexstar 6SE using a smartphone. A small slide switch on the side of the keychain sized unit turns the unit on and off. A blue LED power light monitors the on/off status. When turned on, the iPhone in settings and bluetooth will show the pairing which is nearly instantaneous. Then go to the camera application and use the "remote" shutter to take the photo by pressing its button. The camera will automatically take a photo and keep it. The unit will connect as AB Shutter3. The device will also activate other camera settings like video.
Touching the cell phone to take a photo introduces massive vibrations that blur the image. A remote shutter for iPhone operates on bluetooth, pairs with the phone, and a touch of the remote takes the photo.
This accessory is mandatory for shooting with smartphones. It was purchased at the Night Market for about $3, however the CR2032 battery was not included. A button battery was removed from other electronic equipment to get the remote shutter to work with the iPhone 10 Max XS.
The remote shutter will be an important accessory when shooting images with all observatory smartphones, inclusive of lunar and planetary, solar, and mountain conservation. This newer shutter did not work on the old iPhone 5. For that phone, an older remote shutter is operable. It's also unknown if the wireless remote shutter will work on the Mini iPad which was upgraded to a mini computer. More testing will occur.
