With this adapter you can mount a LS100FHa at your existing refractor telescope in order to use this telescope for solar observing in H-alpha. The adapter is plugged onto the front of your telescope, and the filter can be screwed onto the adapter.
The adapter will be manufactured exactly for your telescope. For this we need the exact outside diameter of the telescope or the dew shield! When ordering, you will find a field for comments, please note there the appropriate diameter.
Note: Please note that front filter can only be used together with a blocking filter.
