The Tamron 17-35 OSD VC F2.8-4.0 lens can be suitable for astrophotography due to its wide focal length range and relatively fast aperture. The wide focal length allows for capturing expansive views of the night sky, while the fast aperture of F2.8-4.0 can gather enough light for capturing stars and celestial objects. Additionally, the built-in Vibration Compensation (VC) can help reduce camera shake during long exposure shots, which is essential for astrophotography. However, it's important to note that dedicated astrophotography lenses with wider apertures may be more ideal for capturing detailed and high-quality images of celestial objects. **
