¤•••••Subject: Minami's Mars drawings

Received: 14 December 2019 at 04:22 JST


Dear Tomoko, Masami, Reiichi and friends,

   Yesterday I began reviewing Masatsugufs observing log books, which are now out of deep freeze (for preservation).  This work was a preliminary to scanning them and putting them on-line for researchers worldwide to be able to access them.  I must admit that I had never had the opportunity to study closely Masatsugufs work—he was somewhat secretive about it—but now that I have had the chance to see what he was up to, my admiration knows no bounds.  I am so glad that Lowell Observatory has been able to accept and take the kind of care of this masterful work that it deserves. 

   Not only was he the most persevering and knowledgeable visual observer of Mars I have personally known, he was also one of the very greatest artists in depicting the Martian features. 

  In advance of the scans, I am sending a few examples of Masatsugufs work from October 2005 with the 91-cm Lick refractor, which I played a small role in helping to arrange.  Unfortunately, another guest proved to be rather annoying—especially to Masatsugu—and the most I contributed was getting him out of Masatsugufs sight for several days (I took him on a trip to Mt. Wilson) so that he could observe Mars all night as long as conditions allowed with Rem Stone, Laurie Hatch, and Tony Misch, all of whom were living on Mt. Hamilton at the time.  Masatsugufs series of drawings of Mars—simply because of the aperture and quality of the telescope and conditions—are in a class by themselves even among Masatsugufs oeuvre, and remind me of the work of such great classical observers as Barnard and Antoniadi. (It makes me feel rather guilty that I wasted some of the valuable time that Masatsugu could have spent at the eyepiece making my own observations—but perhaps I can be forgiven that indulgence!)

   Masatsugu stayed on Mt. Hamilton long enough to catch the development of one of his beloved dust storms—see figure 4 below. 


   Itfs a revelation to be looking through Masatsugufs brilliant work in the archives of Lowell Observatory, where all those log books of Percival Lowell and his associates also reside—and brings home like nothing else the powerful influence of the gpersonal equationh in all the observations that anyone makes.


   More soon, but an interim report for friends


   Best, Bill

¤•••••Subject: Early Mars Images.

Received: 1 December 2019 at 10:53 JST


Hi All,
Here on some early Mars images, taken with an 203mm (8") Newtonian telescope.

Using a ZWO ASI 290mm camera with a proplanet 742 filter and a 2.5X powermate.

These images were taken during daylight hours.



Best to all.
