ZWO 1.25" HA Filter - 7nm

The H-Alpha Narrowband filter transmits only H-Alpha wavelength light, which is found in most nebulae, star clusters, galaxies, and stars. This makes these filters ideal for complex false color imaging of such regions. H-Alpha filters such as this one are excellent for boosting contrast and are most definitely a must have for imaging in areas with high levels of light pollution. This particular H-Alpha filter has a bandwidth of 7nm. Mounted.

Good filter - no threads on the scope side

The filter seems to work well and gives good narrowband views. It works very well for short exposure stacking with a low noise mono camera for quick views. My only complaint is that the filter does not have any female threads on the scope side, only male threads on the camera side. That would've been a nice feature for threading on extension tubes or focal reducers.
