Does this come with the push pins to hang off the outside of the OTA?
Asked by: Michael
Yes it does. You place the mask over the front aperture of your telescope by “hanging” it on the plastic screws from the front dew shield. Take a short exposure. The image of the star will show diffraction spikes. The “center” set will most likely be shifted to one side or the other. This is showing the defocus.
