End of an era?

Hi Astronuts,
Today I finished the last of the 10" F14.5 Maks, which will go to whoever is on our list. This is the last of my hand figured Maks that I plan to make of this size and focal length in production. It used to be that there was much more visual astronomy than there is today, probably because imaging was hard in the film days and for the first couple of years when we had small chips to do electronic imaging. Nowadays it is impossible to get visual views that remotely resemble what you can do with a few thousand bucks worth of electronic equipment.
That said, here is my last production Mak, aimed at a far distant telephone pole insulator which has a glint of sunshine that shows up as an artificial star. With a 5mm SPL ocular (737x) I see a tight high contrast Airy disc at focus. For those who don't know what that is - an Airy disc is the smallest resolvable spot from a distant point source that can be seen in any telescope. For a 10" it's approximately 4.5 arc seconds, and is surrounded by a few faint diffraction rings. With a scope like this I once saw the Sirius Pup in the Florida Keys when the separation was a mere 4 arc seconds.
  Let there be light and minimal obstruction

Thank you for making these superb instruments.
I am very please you made another group as I got one earlier this year. Seeing the one your brought to Astrofest many years ago prompted me to put my name on the list. At the time I had hoped you would make a more portable 8" version and still think that would sell well. I am a portable visual observer and the 10" perfectly fits my needs for a high magnification scope. John |

Do you autograph all of the Stowaways ? No, I did this one on my first prototype at NEAF a couple of years ago for a laugh.

Does anyone know an easy way to either attach wheels or a dolly that will work to move the older and heavier AP 10 inch in its case
around? I think I used to be able to pick the case up with the telescope inside but recently have resorted to pushing and pulling it across the floor. Thanks for any help.
Best,
Jim

Hi Jim
Is your scope case one of the Astro-Physics wood cases ? I had the same experience with my 180 EDT case. As I am getting older the force of gravity is getting stronger. Astro-Physics sold me a set of removable wheels that I installed on my 180 EDT case, but you can also get them directly from a company called Crest Lock. Some people may remember that Hartmann and Boyt suitcases use these wheels before the in-line roller wheels became so popular. Be sure to get the ones with ball bearings. You will need to move the foam on the bottom of your case out of the way to install the receivers, and you should install the wheels at both ends of the case.

Michael,
That’s mighty handy for anyone that has the large cases and lost their wheels or wish to add them. Thanks for posting.
Clear Skies,

I keep the case on a flat moving dolly I got from Lowes or Home Depot. The dolly was left over after a couple of moves. To lift the case in and out of the car I used some retired lengths of climbing rope. The rope is attached under the handles with some velcro strips. The velcro take no load and makes it very easy to remove the rope if needed. The rope also serves as a tow line when pulling the case from storage to the garage. A simple solution with available materials.

I forgot to add that you will want to get
the covers too in case you decide to remove the wheels.
