SolarMax III H-α Filter Sets
Congratulations on your purchase of a SolarMax III H-
α
filter set! Be sure to read the safety and cleaning instructions
on page 6 and 15 before using your SolarMax III filter. 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.
Please read these instructions in full before setting up your new filter set.
Before purchasing any of the accessories listed below please contact Meade customer service for guidance regarding
correct selection and mounting.
Mounting to Your Telescope
With the exception of a few refractors, mounting will typically require a custom adapter plate to mount the etalon filter
to your telescope. Meade does not manufacture or supply these adapters and is not responsible for the performance
and safety of our filters when used with these adapter plates. When mounting Coronado filters on telescopes other than
Coronado SolarMax III telescopes, the user assumes the responsibility for the correct mounting and safety of the system.
Never point your telescope at the sun until your filter set is fully assembled on the telescope. Your telescope should be fully
mounted and pointing away from the Sun while attaching the filters. The etalon is designed to be mounted on the objective
lens of your telescope either directly or via an adapter plate. Make sure that the etalon is fully threaded into the adapter
plate or telescope objective cell.
Blocking Filters
This is an essential component of your H-
α
set up and must be installed for the system to work and be safe to use:
BF10, BF15 - Each of these are housed in a 1.25” right angle diagonal with 2” nosepiece. Slide the 2” barrel into the focuser
and secure in place. If you have a 1.25” focuser you will need a reducer or adapter to 1.25”. Call Coronado for details on
obtaining this adapter.
BF30 - The BF30 blocking filter is designed for use with telescopes of focal lengths from 1,500mm to 3,000mm. Slide the
BF30 nosepiece tube into the focuser and secure it in place. Coronado recommends using 1.25” eyepieces for visual work.
Some 2” accessories may not come to focus and are not recommended. Most 2” eyepieces have many lens elements
which may cause excessive internal reflections when viewing the Sun.
