I like to share a nice cooperation work with Russell Croman.
We agreed to image the sun at exactly the same time, me with my 4" TMB in white light and Russ with his 4" Televue 101 refractor in H-alpha focusing on the very active group 365.
We did it last Friday at 13:30 UT, he in Texas in the morning, me in Austria in the afternoon.
The combined result was very interesting, it shows not only different structures but also clearly the different height of the chromosphere (H-alpha) compared to the photosphere (white light).
Enjoy:
