Astrophotography Fit
A supporting filter that should match the camera, telescope speed, and target type.
Optolong L-Pro Filter - 1.25" Mounted is a budget-friendly astronomy filter (1.25").
A supporting filter that should match the camera, telescope speed, and target type.
Choose filter size around the sensor diagonal, telescope speed, and filter-wheel or drawer geometry. Flats are still required; a filter can improve contrast, but it will not rescue tilt, bad focus, or poor calibration.
Best paired with
- Cameras and filter holders with the same physical size
- Targets that match the passband
- A calibration workflow that includes flats after filter changes
Not recommended for
- Using as a fix for poor focus, tracking, or gradients
- Filter sizes smaller than the illuminated sensor path
- Targets outside the filter passband
