Sunspot AR 2767 in white light
Was pleased to note a sunspot was visible on the Sun's photospheric surface today so chased after it.
This is a fairly simple sunspot with a small dark pore seen down at 5 O'Clock. Filaments are seen in the gray penumbra and the background surface of the Sun shows granulations (individual convection cells) quite well - the atmosphere was not turbulent when this was taken this AM.
By the McIntosh classification system it is:
HSx - simple unipolar sunspot with a symmetric penumbra
900mm f/7.5 Skywatcher Equinox ED scope
x3.0 Explore Scientific Focal extender.
Baader Herschel safety wedge
ZWO 174 MM monochrome CMOS camera
Skywatcher EQ6 mount with Rowan belt drives.
Hinodi solar guider.
Best 50% of 4000 frames
