Coronado SolarMax II 40 / RichView Tuner Package for Double-Stacking SM40 Filter Set or Telescope

Increase the amount of detail you can see through your SolarMax II 40 filter set or SolarMax telescope when you add a second filter! This is a genuine Coronado Instruments SolarMax II 40 / RichView unit that will, when properly matched, narrow your bandpass to <0.5 angstroms, greatly increasing the amount of surface detail you can see and image with your SolarMax 40 telescope. The unit is a second SolarMax II 40 filter and RichView just like the primary unit on all SolarMax II 40 Telescopes. The new unit will fit directly to the front of your existing unit, by means of an adapter plate (sold separately).

This filter CANNOT be used as a stand alone solar filter. Immediate and irreversible eye damage may result

I bought a base level PST, the sun was fun to look at but lacked the ability to show any surface detail. So it tended to sit more than get used.

The SM40 comes packaged in a very nice foam lined hard case and a manual that covers several solar telescopes.

The filter screws directly to the front of the PST and the adjustments are easy to learn from the well written instruction manual.

With this second stack filter the suns ball really pops with surface detail in 3-D. Wow!

If you have a Coronado PST single stack and want it to pop when viewing the sun, the SM40 works very well.

I gave it four stars simply because I thought it costs too much.

Aside from the cost being more than the whole PST, it's a value compared to buying another system.

Morning. I have a 40mm PST solar telescope and would like to double stack it. I see you have the Coronado SolarMax II 40/ RichView Tuner Package. Does it need or come with the adapter ?? If it needs an adapter, please let me know and what your part number is. Please advise. Thanks. Dave
Dear Friends, I am asking about the size of the packaging box of the Coronado SolarMax II H-Alpha Double Stacking Etalon Solar Filter (40mm) as well as the total weight of the shipping package. Thank you for your attention.
