ฟิลเตอร์ส่องดวงอาทิตย์ iOptron 70mm Adjustable Solar Filter (Solarite), ID 84-106mm
White light solar filter with SolarLite solar film from Thousand Oaks Optical which has the optical quality of the glass with the advantages of impregnated polymer. Unlike the pale white image from Mylar film, it provides a nature yellow-orange solar image. The filter will never develop pin holes or scratches that can let in light and ruin a filter. Will not tear or puncture. It also has a flat surface compared to other thin film filters that have wrinkles and creases. The machined aluminum fixture makes the filter very sturdy yet light weight.
This filter fits most 70mm to 90mm telescope tubes, as well as some camera lenses. It has an inner diameter from 84mm to 106mm and clear aperture of 70mm.
Zenithstar 73 is a greatly versatile and portable refractor telescope for beginners and veterans alike. Designed for both astrophotography and wildlife photography, high power visual observing through the Zenithstar 73 is also hugely satisfying. The image is crisp, sharp and colour aberration free thanks to the use of top quality glass — FPL53, closely matching the legendary fluorite material. The 43mm image circle when Flat73 is used covers full frame size sensor nicely.
William Optics Micro 4/3 48mm T mount for Olympus - Space Gray
This high precision T-Mount has 48mm threads with outer hard gray/red color anodizing and its made from High quality aluminum material by CNC with perfect fitting !
The CEM26 is fantastic mount, very smooth gearing and extremely easy to set up. Linked with the Polar system is great, although you have to buy the separate APP to use it if you are on a MAC which is dissapointing but it works flawlessly.
