Coronado SolarMax II 60 60mm f/6.6 H-alpha Double-Stack Solar Telescope (15mm Blocking, OTA Only)
Key Features
  • Double-Stacked H-Alpha Etalons
  • Patented RichView Tuning
  • Improves Surface and Prominence Contrast
  • 400mm f/6.6 Solar Viewing Refractor
Coronado's versatile SolarMax II 60 60mm f/6.6 H-alpha Double-Stack 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.

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's versatile SolarMax II 60 60mm f/6.6 H-alpha Double-Stack 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.

Its primary internal etalon provides a bandpass of 0.7Å which will reveal prominences in high contrast. Prominences generally appear larger with this size filter than in narrower bandwidths. This version of the SolarMax II comes with a secondary etalon that fits on the front of the OTA and narrows the bandpass to 0.5 Angstroms. At this bandpass, surface contrast is improved versus wider bandpasses. This ability to change the bandpass allows users to see more areas of the Sun than with a single-etalon solar scope. Complementing the etalon filters 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.

question

Will this work with Coronado PST?
Asked by: Anonymous
Yes it works with the 40mm PST. It greatly increases the surface detail of the sun e.g.. filaments, sunspots and the bubbly effect of the surface. The prominences,solar flares on the edge of the sun are still visible although with less contrast. Ian Hynes recent purchaser of both

question

When you look through it do you see the sun and it's right orientation or is the sun flipped 180?
Asked by: Anonymous
It' just like any other telescope with a diagonal. Left and right are opposite.

question

Since this tripod and GoTo mount are being matched up with a solar scope does that mean that this GoTo will track the Sun? Some do not have the Sun as a preset object to track.
Asked by: Gary I.
Yes this All View Mount can track the Sun.
