[. . . ] Never allow unattended children to operate or be near a solar telescope system. Coronado SolarMax and SolarMax II hydrogen-alpha telescopes and filters are designed and tested to provide safe viewing of the Sun. These systems consist of two critical parts: The etalon filter that may be mounted at the front of the telescope or internally inside the telescope tube and the blocking filter that is mounted at the back of the telescope. Both of these components must be properly installed to provide safe solar viewing. [. . . ] This is also compatible with piggyback mounting systems. Meade manufactures and sells separately one mount suitable for the SolarMax II 90: The LXD75 German equatorial computer controlled mount. Meade also makes a dovetail mounting block (product #DT-LXD75) compatible with the LXD75 mount and many other mounts on the market. Draw Tubes - The SolarMax II 90 telescope has a very fine adjustment helical focuser that rotates around the OTA in order to achieve focus. This focuser also has two drawtubes that will need to be adjusted for "rough focus". To do this locate and loosen the 2 nylon set screws located in-between the gold colored OTA and the helical focuser. Once the nylon set screws are loose, fully extend draw tube #2. Retighten the set screws before proceeding. To extend drawtube # 1 locate the set screws between the helical focuser and the end of the telescope. Once loosened the drawtube will extend but cannot be removed. Retighten the setscrews before proceeding. The BF30 version will appear to be the same. However the BF30 will be mounted inside the telescope and the diagonal supplied will be without any blocking filter. The SolarMax II 90 telescope with an internal BF30 can be used without the diagonal to mount imaging equipment in a straight through configuration but drawtube #1 will still be 1. 25". If you have the BF15 version you MUST use the diagonal. You cannot substitute another diagonal for the Coronado Blocking Filter Diagonal. This would create an unfiltered system and deliver light from the Sun that will cause damage to the eye. Contact Coronado if you are unsure which version you have.

You can refer to the diagrams below for questions regarding the components of your system. Never point your telescope at the sun until your filter set is fully assembled on the telescope. [. . . ] The more you view the more detail you will pick up. The average observer takes around 3 months to become fully accustomed to viewing subtle detail in H-a light . Another important factor is the weather, bad seeing conditions will limit the amount of detail you can see. 16 Meade Instruments Corp. Warranty for Coronado Products Meade Instruments Corp. [. . . ]
