"Scientists and artists are very much alike. They are searchers asking questions about human problems. They open the world up for us to show how little we really know, to keep us interested in life."

Latest Astro-Photo:

Lower prices for backlit prints!


My backlit astro-photo prints have always been popular, but the high cost has been prohibitive for many.  I have been working to reduce the manufacturing cost and am pleased to announce that I can now offer these prints at a substantially lower price. Click here for details!

PerfectTemp temperature sensor:  This optional accessory to the PerfectStar Focus Controllers provides enhanced performance for temperature-compensated focusing.

Latest News & Products Announcements:


To get the latest news from WO more frequently (and less formally), check out the Facebook page:  The FB page will be updated more frequently than this web site, and will include more information about what I am up to, in both astro-photography and product development.  

Together At Last!


We are pleased to announce that we can now offer the Hotech SCA, the perfect companion to our MRT adapter.  Together, they complete the rock-solid connection from telescope to camera!

Latest News & Products Announcements:


Permanent Focus


Version 5.2 of the PerfectStar Focus Controller firmware (available on the Support page) adds a new feature called “Permanent Focus” that maintains focus from one session to the next.  With this feature, a fixed installation such as an observatory, might operate for a very long time without having to adjust focus.



2015 Calendar Now Available


I have been publishing a calendar of astro-photos each year for several years, but in the past it was always at the end of the year, which left only a couple of months to sell it.  So starting now, it will be printed in August (in time for the Oregon Star Party)

AO Article in ATT


Astronomy Technology Today is a bi-monthly publication that focuses on the equipment used by astronomers.  In other words, it’s a magazine for astronomy “gearheads”.  The July/August issue includes an article I wrote titled “To Chase a Star”, which describes my experiments with amateur adaptive optics.  Check it out at


ASCOM Driver Update


Version 6.1 of the PerfectStar Focus Controller ASCOM driver is available on the Support page.  This update fixes the awkward handling of unexpected disconnects or USB failures.  It is recommended for all PerfectStar users.
