SAFETY FIRST: Observing the Sun without the proper protection may result in serious personal injury, including permanent eye damage and blindness, and/or damage to equipment. Never point an optic at the sun without an approved solar filter on the front of the optic. For direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder, ensure your filter is ISO 12312-2 (also written as ISO 12312-2:2015) certified. Never use photographic neutral density filters for direct solar viewing, viewing the sun through an optic, or when using cameras with an optical viewfinder.

Coronado SMT60-15 overview

Coronado's single-etalon SolarMax II 60 60mm f/6.6 H-alpha Solar Telescope is calibrated for the hydrogen-alpha wavelength, and comes equipped with their RichView tuning system. This system allows direct adjustment of the primary etalon filter enabling it to be tuned up or down from the 6562.8Å wavelength for highlighting specific zones of the chromosphere and to compensate for Doppler shift that can pull prominences and other features off-band and affect views. Tuning areas of concentration back on-band, allows for higher-contrast views of prominences on the solar limb.

Complementing the primary etalon filter is a rear 90° 15mm blocking filter. This secondary filter further isolates the H-alpha wavelength for better views. While a smaller blocking filter would suffice, Coronado includes this larger option to allow the use of eyepieces with larger field-stop diameters to be used without vignetting occurring, as might be seen with smaller filters, which would interfere with the field of view.

The SolarMax II is offered here without a mount or tripod, but comes with a wide clamshell mounting ring that is outfitted with a 1/4"-20 socket for attachment onto many photo/video/field tripods or on piggyback rigs, or an optional Vixen-style dovetail plate is available for use with conventional alt-az, EQ, or motorized telescope mounts.

    Coronado SMT60-15 reviews

    SolarMax II 60 60mm f/6.6 H-alpha Solar Telescope (15mm Blocking, OTA Only) is rated 4.5 out of 5 by 2.
    Rated 5 out of 5 by from Excellent scope Wanted to be able to view and photograph some of the recent solar activity and this was definitely the way to do it. I chose the SolarMax II 60 (w/BF15) over a Ha filter system for my telescope. This scope has the adjustable etalon filter. The scope can be tuned specifically for viewing the surface details and prominences or for viewing sunspots only. Feels well built, the only concern are the nylon screws for holding the draw tube in place. They feel like if they were over-tightened they could snap off. Attaching a barlow or powermate and a DSLR adds a lot of weight so you want to make sure the draw tube is secure, but you don't want to snap off the screws. The photos I can get are amazing. Though it does take some time to learn how to expose for which details - overexpose for prominences and underexpose for surface detail. Best image results are obtained with a monochrome planetary imaging camera instead of DSLR. Definitely happy with my purchase!

    Rated 4 out of 5 by from Great Views Even though there isn't much solar activity right now, there's still plenty to see.� Easy to get it tuned to see prominences, a bit more work to see surface detail, but I was able to do it my first time out.� The helical focuser could be better, but that's my only complaint.
