Daystar chromosphere model, simply tune with the adjustment knob to see prominence. 8 months old, works great but I have become fascinated by calcium so time to sell this before I start down that route.Just like it shows, comes with power cord and matching battery to take further away from home, 2” and 1.25” nose pieces, has a ZWO 1.25 filter installed, cannon adapter rings for front and back, a 400-800mm camera lens, and extra mount foot. Will work with included telephoto lens if you unscrew the nose pieces to attach the lens, and simply put a dslr, astro camera, or eye piece on the back. It works best on a telescope though at f30 or over, has a 4.3 barlow built in so if you have an f7 or longer scope is ideal. From the photos you can see the battery holds full charge, cord plugin on quark is in mint condition, and unit comes on band.
