The Coronado SolarMax II 60 H-Alpha Filter is part of a series of thermally stable H-alpha filters for installation on the user's telescope. All the filters in this series are thermally stable and mount to the front of of the telescope. They provide very high resolution and give unsurpassed views of the finest of surface details, including plage, flares, filaments, prominences, and granulation when mounted to a good quality telescope.
Coronado SolarMax II 60 H-Alpha Filter with BF15 and RichView Tuner
This SolarMax II 60 comes with a BF-15 blocking filter, a secondary interference filter which mounts at the eyepiece end of the telescope. You cannot use the individual units (either the blocking filter or the front-mounted SolarMax's) separately. The BF15 is mounted inside the body of a 1-1/4" right-angle diagonal. It is optimized to provide a full disc image on telescopes with a focal length of up to 1500mm.
About the RichView Tuner...
Some events on the Sun, notably active flares and coronal mass ejections (CME's) are extremely fast moving. If such features occur on the disc of the Sun, their high velocity towards the observer results in their wavelength being Doppler-shifted shorter than Ha. If the velocity is high enough, this wavelength could be outside the passband of the filter and the feature would not be observable. The RichView allows the user to de-tune the SolarMax II slightly to bring such phenomena into better visibility. The RichView fits between the SolarMax II and it's adapter plate, sold separately. A simple rotary wheel movement accomplishes the tilt necessary to move the passband of the filter. Because of the filter's position at the front end of the telescope, this does not compromise the performance of the filter nor limit the Ha field of view as is the case with rear-mounted filters.
Below you'll find a list of explanations regarding important accessories that may be required for this product.
- An adapter plate is required to attach this filter to your telescope. Coronado is no longer producing these adapters however, Ashley Precision Parts is providing custom adapters for our customers. Please provide the telescope you will be adapting to, the outer diameter and whether you need a slip fit or threaded plate, in the comments section during check out. If you have any questions regarding these plates, please feel free to email our internet sales team for more information.

Had a Coronado PST and loved it....after about year decided time to move up....Had moderate expectation..How much difference could there really be....a novice to Solar Astronomy
So to speak..The difference is absolutely incredible ...the detail in the prominences..flares ...spicules....filiments ...sunspots ....all Sharp and defined with breath taking clarity
Also the Coronado Solar Max II is far and above the PST in
It's feel and manufacture...so much more refined and robust..
Controls smooth as silk....
Was it worth the investment...you bet it was...

Product QuestionsHello, I have plan to buy a CORONADO SOLARMAX II 60 H-ALPHA FILTER W/ BF15.
>Threaded to fit the TeleVue Pronto or TV76, but can fit on other instruments with proper adapter plate (sold separately).
Do you sell a plate for my FS-60CB TAK?Question by: Tatsuji Tanaka on Sep 19, 2016 1:18:00 AMI presume this is a replacement objective for a 'donor' telescope? The original objective cell is removed and replaceed with the Coronado objective - using an adaptor plate of course. Also what is the minimum focal length to which this can be adapted?Question by: Mike Chapman on Oct 26, 2016 6:35:00 PMActually, no. This is an etalon and blocking filter combo to convert a conventional telescope (Like a TV76 refractor) into an H-alpha solar scope. This etalon does not include an objective lens. You can mount this to any telescope you can adapt it to, but you may need a custom machined adapter in the front and you must use the 1.25" blocking filter in back to make the image completely safe for visual or imaging use.Answer by: Chris Hendren on Oct 31, 2016 4:33:00 PM
