views on a small monitor of many
prominences, with occasional filaments,

during this period of solar minimum.

Likewise, I tried imaging with the
SS60C using a Celestron Skyris 236M
video camera. The 236M’s small 5.44 ×
3.42-mm chip could capture only about
25% of the solar disk with no additional
focal reducers. For increasing the field
of view, the manual recommends the
addition of a 1¼-inch-format, screw-on
focal reducer offered by several third-
party manufacturers when imaging
with video cameras. Using one I already
own enabled the camera to see about
75% of the Sun using the Skyris 236M.
With the versatility of the Solar
Scout 60C, there’s no need to be
discouraged when a spotless Sun is
the rule around times of deep solar
minimum like we’re experiencing now.
The lack of sunspots doesn’t mean there
isn’t a dark, sinuous filament stretching
across the Sun’s disk or dramatic
prominences dancing along the limb.
We just have to be tapped into the
hydrogen-alpha world to see and image
those very compelling solar attractions
within the chromosphere.

the Daystar Solar Scout, JOHNNY
HORNE may have lost some weight
using the SS60C in the hot summer Sun.

SLeft: Attaching video or deep sky astronomy cameras can be accomplished using the 1¼-inch eyepiece adapter, though a better option is
Daystar’s Interference Eliminator mount (https://is.gd/cmount), which enables users to slightly tilt the camera to correct for interference banding
that often appears when using monochrome cameras. Right: The Quark unit of the SS60C can be removed and used on most small refractors with
the addition of a 1¼- or 2-inch nosepiece adapter (above).
