DS 60mm Maxscope, LXD75, 21-7mm Zhumell

Sketch created scope-side with black Strathmore Artagain paper, white Conte’ crayon and pencil, Derwent charcoal pencil, black oil pencil

The LXD 75 had a little bit of a fit for tracking at the beginning of the session and because I had already made the first markings on my paper for the large SW prominence, I continued sketching, having to unlock the clutches and manually move the scope a few times during the short period it took to complete the sketch. After restarting the mount’s computer, it worked just fine and I was able to sit comfortably as it tracked perfectly for the full disk sketch.

There was another large prominence to the south in the shape of an “A” as well as a NE prominence that had a very thin sliver connecting a larger blotch of plasma that at first seemed to be floating above the limb unattached. Several other smaller prominences scattered the limb and are shown roughly on the full disk sketch. It took a little effort and moments of clear, steady skies to show the finer, faint tendrils reaching above the large prom to the SW that I’ve sketched. Just for kicks, I digitally colorized it and flipped it to match a standard orientation.

The active regions and filaments were a sight to see, especially the band of plage areas (even though very small areas of plage scattered about) that reached east to west in the northern hemisphere. The two active regions to the south were almost mid-line and had brighter plage compared to the northern ones.

For comparison, Paul hooked up his camera to the Maxscope when I was finished with my observing session.
