Hi Astronuts, I have seen this question asked on other groups by people who wonder whether it is worthwhile to have encoders on a mount and what it will buy you in terms of performance. To answer the

I have a question regarding encoders and wind. Do encoders make a vast improvement in gusty wind conditions?

The encoders cannot anticipate wind but can react to it after the fact. So you will have excursions but the axis being affected will recover much faster when the encoders are on. The best strategy is

Can someone give an estimate of height "B" in the attached image for the new Mach 2 mount? Thanks!

Thanks, I'm at 38 deg. latitude so I'm guesing it'll be an inch or so lower. ...just trying to calcuate the needed pier height. Doesn't have to be too precise.

A better approach is to use the Planewave tool and input the 3 measures it asks for. It can then calculate any altitude, Dome radius, pier offset, and pier height

Hi Stacey, If you arenβt aware, PLANEWAVE has a really great PIER HEIGHT CALCULATOR spreadsheet program. http://planewave.com/downloads/tools/ Simply enter your scope and pier dimensions in the boxes,

I calculate about 105/8" based on Roland's measurements and your latitude. The formula to calculate your dimension B is 12.25 times the tangent of 38 degrees divided by the tangent of 42 degrees.

What is there about the keypad that it would be delayed? I thought all of the software issues would be in the control box. Larry

Larry, AP can correct me if Iβm wrong, but I suspect for example the modeling software runs on the keypad and the correction parameters are stored in the CP5.

The keypad program has actually been totally rewritten using newer procedures and commands, which is why it must be used with the GTOCP4 or CP5. The startup routines are easier and there are other goo
