Designed and Manufactured in North America.

It has a new 2" two-speed rack & pinion focuser with both coarse and fine focus controls which provide the user a more precise focus, critical for both solar imaging and visual observing.

Additionally, the SM3 90mm includes only external "True" H-α etalon filter giving higher contrast views and sharper features compared with models using smaller internal H-α etalon designs. Experience darker backgrounds, sharper features, and higher contrast with the new SolarMax III series telescope.

Also includes Coronado's patented RichView tuning allowing direct tuning of the primary etalon filter. The patented RichView tuning technology provides additional tuning range and an overall better way of adjusting the filters bandpass. Now you can tune for the highest contrast views of your favorite solar features without sacrificing image quality.

This telescope with enhanced rack & pinion focuser and large external etalon is now the perfect way to view the Sun! The SM3 90mm comes with an included 12mm, 18mm, 25mm CEMAX eyepieces, CEMAX 2x Barlow, Sol Ranger Solar Finder, 30mm blocking filter, Vixen-style dovetail mounting rail, and an all-new black and gold Aluminum Hard Carry Case (Dimensions: 26.5" X 8.66" X 8.66").
