In brief:
- Fast photo Newtonian for astrophotography
- M48 connection thread for cameras
- Sensitive focuser with 1:10 reduction
- Extra-thin secondary mirror mount
This Newtonian is a compact, very fast instrument (f/4.0) for high-resolution astrophotography with short exposure times. It is ideal for large emission nebulae and galaxies. Despite the fastfocal ratio and optimisation as a photo Newtonian, it is also a pleasure to use for visual observation, especially for deep sky objects! The large focuser with 1:10 fine drive allows for a bright image field and precise focusing. The secondary mirror struts are kept extra thin to cause as little obstruction as possible in the optical path, resulting in better contrast. The generous back focus of 83.2 millimetres leaves enough working distance for additional accessories, such as a coma corrector or filter wheel. For astrophotography with this fast aperture ratio, you will definitely need a good coma corrector to maintain sharpness and point-like stars across the entire image field. With smaller camera sensors and purely visual use of this Newtonian, a coma corrector may not be absolutely necessary.
The scope comes with an 8x50 finder, a 35 mm extension tube (important for visual use), a 26 mm Super Plössl eyepiece and a fan for faster cooling of the primary mirror.
