His obituary can be seen on the Astronomy Magazine website:   http://www.astronomy.com   Go to Blogs. 

Tomm’s website can also be accessed from the obituary. 

I purchased his fabulous star atlas in 1992:  1000+ The Amateur Astronomer’s Field Guide to Deep-Sky Observing.  This atlas has inspired my personal astronomy observations and I continue to use it.  In 1993, I was fortunate to have the opportunity to meet Tomm.  He encouraged me to continue with my telescopic observations and especially sketching at the telescope.

The following group photo was made in January 2003 at Gardner-Webb University in Boiling Springs, North Carolina.  The purpose of the event was the annual “Regional Meeting of Amateur Astronomer’s.”

Tomm is second from the right on the front row (wearing shorts) and I’m standing to his right with the light blue shirt…

Meade Model DS-10A “Vintage Reflector Telescope” That Still Does The Job.

I purchased this 10-inch classic Newtonian reflector almost 25 years ago and it continues to be the telescope I use the most.  It  was the following advertisement that caught my eye in the late 80’s.  I wanted the DS-16A, but I knew it would be too heavy and large, so I would later choose the 10-inch version.

Double Star M40 and Galaxies NGC 4284, NGC 4290

Due to our recent cloudy skies, I was unable to make a new observation of M40, and galaxies NGC 4284 and NGC 4290.  This forced to use a sketch and notes from an early morning observation on February 25th 2000.  On that night I was using a 10-inch reflector from my moderately light polluted backyard with a 5.8 NELM. It was an especially good night with excellent transparency.

M40, a pair of 10th magnitude stars, also known as Winnecke 4 is very easy with a wide separation of about 50 seconds of arc. The pair is oriented mostly east-west and both appear as whitish-yellow in color.

Two faint galaxies are located very close to M40.  All three objects are located within a 1/2º field-of-view.

Just to the west of M40, lies faint galaxy NGC 4290 at 12.0 magnitude, elongated NNE-WSW. A very subtle brightness could be seen in the central region. Very close and to the west of NGC 4290 is very faint 14th magnitude galaxy NGC 4284, which is extremely difficult, appearing as a faint mostly round blur.  During a previous observation from the same location and in a side-by-side comparison with the 10-inch reflector, NGC 4284 could not be seen with an 8-inch Schmidt-Cassegrain telescope.

The following sketch was made using various graphite pencils and a blank 5 x 8 notecard with the colors inverted using a scanner. 

Double click on the following sketch to enlarge and see very faint galaxy NGC 4284 toward the west.
