Are there more RHA's in the production line at some stage of manufacture?

Greg,



I seem to recall you were looking for an AP160 and there is one such

unit available right now on Astromart.



However, some friendly piece of advise: go after the RHA rather than the

AP160 if you can swing the price of the RHA ;-)



My AP160 and I are attached at the hip but the RHA is something else!!!



Anthony.

I am working on 7 optics sets right now. One is finished and tested, two

more are under test on the night sky.

Just wondering, if it is not proprietary,how many man hours does it take, approximately, to build the RHA?

Building one, i.e. putting it together, doesn't take long, but there is a

lot of time spent figuring and testing the optics. Then it's all taken apart

again so that the glass surfaces can be coated. It also takes a long time to

grind, polish, edge and center each element.

Thank you Roland.



I am on the list. Would a 900 mount hold it, a 80mm guide scope and an SBIG 10 camera with filter wheel comfortably or should I upgrade to a 1200?



Thank you for you guidance (pun intended).

Rolando, how much leadtime do we get on notification? Are the 7 you're working on now all going to people who know they're about to get theirs? Hopeful and inquiring minds .... :-)

I have imaged with one on a 900 mount in my observatory. Even though it's

heavy, the scope is short enough and does not present much of a torque load

to the mount. A 1200 is more stable if you are not inside the walls of an

observatory and have to contend with a lot of wind.
