I don't have a 175 here at this time, but I did try a customer's 180. It worked fine, but it really needs to reside on an 1100. Roland

If you don't use PEC then the stars will wander back and forth by the amount of the PE error. So you will get an oval star image in the RA direction. Roland

I managed to get 6 x 20 minute H-a exposures with the 10" Mak Astrograph on the fully loaded-for-bear Mach2 mount. All exposures were unguided and stacked in MaximDL. Processed in Maxim DL and Photosh

Stop is a software command, so it requires a working servo system. Once the encoder connection fails, the servo loop is broken and no software commands will do anything. In later versions of the servo

No, false. Gears do not mesh better with an off-balance bias. Rolando

You probably had corrosion on the pins of the Y cable and possibly on the motor box as well. Inserting the cable a couple of times might have wiped the pins somewhat clean, but there might still be a

The problem may be unbalance in Dec. If not that, then we may have you slightly back off the Dec motor belt tension. That will fix it for sure, but is a bit more involved for you to do. Shoot me an e-

Your problem has nothing to do with the hand controller. It is just a planetarium program that only sends RA/Dec co-ordinates to the mount when you enter it. Otherwise it is silent and does not commun

We are working on making all keypad modeling available for the CP4. Roland

No, the Ortho is always on regardless of whether you use or turn off any of the other keypad models. Once you enter ortho data it stays there until you overwrite it by doing a new ortho routine. Rolan

In case you didn't see my previous e-mail: What is your power source? The button rates (xand 1200x) are not the same as the slew rate. The slew rate during a move to Home or to any sky position is nor

Are you using 12 volt supply or 24? Rolando

APCC does not erase the keypad ortho model. The keypad model resides in the CP controller and is used to compensate for non-orthogonality at all times, whether an external model is used or not. Once c

You can use them but only if you first create the keypad ortho model and load it into the CP4/5. Once that is done, it will simply make pointing for external models easier. What you should not do is t

#Mach2GTO #APCC #Keypad

The CP4/5 controllers are totally independent of anything that APCC does. APCC models are not loaded into the CP controllers. The way it works is like this: 1) if you do NOT create an Ortho model with

Again, time. The altitude of any object in RA is determined by time. The altitude can also vary somewhat depending on how level the mount head is. Rolando

Hello, You did not get this mount directly from us at Astro-Physics. We shipped this mount in February, and we never ship things loosely in the box, so whoever shipped it to you did not pack it correc

Always have to be able to change mounts and setups for testing issues that come up. Rolando

The 1100/1600 encoder mounts use the original park positions based on time. That's because the encoders are attached to the worm wheel, not the output shaft. There was no way to attach any encoders to

I use off-axis guiding and lock my focuser, so there is no effect from cables dragging. Might be a problem if you use a separate guide scope? Rolando
