ThermaCELL® Mosquito Repellent Lanterns and Appliances are powered by a single butane cartridge. Butane provides the cordless, portable heat that activates the patented devices.
The heat generated by the butane cartridge is directed to a metal grill that is part of the design of the Lantern or Appliance. A small mat, saturated with repellent, sits on top of the metal grill. Heat vaporizes the repellent, allowing it to rise into the air.
The repellent is allethrin, a copy of a repellent that naturally occurs in chrysanthemum flowers. It repels mosquitoes, black flies, and no-see-ums, and will not harm humans or pets.
Within minutes after turning on the Lantern or Appliance, the repellent creates a 15 by 15-foot (225 square-foot) area of repellency, the size of an average deck, patio, or campsite. All ThermaCELL Mosquito Repellent products use the same refills, which contain both repellent mats and butane cartridges.
I bought the Zenith Star 103 last year, it had 30% discount and it is my first telescope.
I use it with a 0.8 reducer on an AM5 mount and connected to a ZWO 183 mono camera. This focal length (575mm with reducer) is versatile, it can be used especially for Lunar imaging and it is also quite fit for some of the most popular deep sky objects too.
The moon photography I get with this scope is excellent, beyond what I expected. I also captured some great images of Orion Nebula, Horsehead, the Pleiades, M33, Rosette, Flaming Star etc. After one year what I can say is that I love this scope, I will certainly keep it. I might buy another one with a shorter focal length to cover different targets, maybe Redcat 51 or ZS 61. The convenient focuser and its 360° rotation ability in Zenith Star scopes is something I'd like to keep.
