Sunspot AR2529 in H alpha and "white" light


Recommended Posts

Hi all,

today I sketched the wonderful sunspot AR2529 in both H alpha and in "white" light. In fact, in order to have a quick comparison of the two spectral ranges without swapping scope and eyepiece, I simply detuned the pressure tuner of the Lunt completely. It worked sufficiently well: When being fully detuned, the Lunt just shows a red sun with sunspots as if they would have appeared on a white sun with normal telescope and solar filter. :)

Here's my sketch:


Telescope: Lunt LS50THaB600PT

Eyepiece: Skywatcher Planetary 5mm

Date & Time: April 15th, 2016 / 1730-1815 CEST

Location: Home terrace, Dusseldorf region, Germany

Technique: orange and white pastels and pastel pens, charcoal pen on black sketching paper.

Hope you enjoy it!
