Sharpstar 30085NTRD 3-inch 0.85x F3.4 Full-frame Astronomical Coma Corrector for Newtonian Reflectors
Description:
- The Newtonian reflection system has always been a popular model among astronomy enthusiasts, and it is also one of the relatively easy to understand and use telescope systems. The visual Newtonian system has relatively simple requirements, but in terms of photography, if high-quality shooting is needed, a coma corrector needs to be introduced.
- The 30085NTRD coma corrector emerged in this environment. It adopts a 3-inch specification, 0.85x reduction, supports full frame photography, has excellent quality, and outstanding effects.
- It transforms an F4 Newtonian system into an F3.4 full-frame photography system after adding this coma corrector. Additionally, the rich threaded interface can be matched with numerous photography accessories, and the front end has M82x1 external threads that can be connected to our new 3-inch focusing device or other brands with corresponding threads. The rear end has M76x1 external thread, M68x1 internal thread, and standard 55mm rear intercept M54x0.75 internal thread, which can be directly connected to our M54-M48 dual-purpose camera adapter.
- The use of this coma corrector has significantly improved the peripheral star points and has a good correction effect on other aberrations, making it an essential accessory for Newtonian reflectors photography.
