Starlight Integrated Paracorr System (SIPS): The SIPS is an integrated focuser-mounted version of the TeleVue Paracorr Type 2. This Coma Corrector functions with Starlight Instruments finely crafted Feather Touch focuser and combined with TeleVue’s 1st-class optics, which together, makes this the ultimate coma corrector.
The advantages of the SIPS Coma Corrector is once it is set-up, there is no need to fumble with locking screws, turning your flashlight on to check its position, etc. This saves time and hassle. Also, the assembly is more rigid and flexure is greatly reduced. The SIPS Coma Corrector totally eliminates the need to re-adjust/calibrate when switching eyepieces. You will simply adjust the focus knobs of your Feather Touch focuser for viewing. Because of this, the SIPS Coma Corrector will save you valuable observing time, less hassle and ease of use.
