Sharpstar 2.5" F4.4 Full-frame Reducer Professional Astronomical Accessory Dedicated for 94EDPH Telescope
Description:
- 94EDPH F4.4 dedicated full frame reducer, meeting the needs of full frame photography, using a 2.5-inch lens specification, with one end threaded M74 x 1, connected to the main mirror focusing device; The thread on the other end is M48 x 0.75, with a intercept of 55mm when connected to the camera end. The reducer is a four piece fully separated structure that supports full frame photography, with a good image range of up to 50mm and excellent peripheral dimming control. The reduction ratio F4.4, combined with 94EDPH, reduces the focal length to 414mm, making it the preferred choice for deep space astrophotography.
- Another highlight is that the F4.4 reducer itself is equipped with a 360 degree rotator, making it convenient for the camera to rotate and compose during photography. The M48 interface contains a 2-inch filter thread for easy connection.
