AP1100 CP4 pier crash

Sure would be nice if a meridian flip fails for some reason, power is left on and forgotten about, or if connected to a laptop and the laptop crashes and the mount has nothing to tell it to stop tracking or park at the end of the night. All that is already in APCC. The mount can be programmed to do all of the above.

I know APCC addresses some of these situations, but requiring a computer to be connected at all times is not always ideal. Seems like it would be a huge bonus to safety, we have some pretty expensive equipment riding on these mounts.

I typically don't use a laptop when I image so APCC won't be of any help. Is what Christopher said true? Can this really be done on the CP4?
If not, is it possible this could be added? Some simple safety limits (at the CP4 level) past the meridian sure would give some piece of mind that our investments are protected and I'm sure would prevent many of the crashes we hear about, something as simple as "if the mount reaches X minutes past meridian, stop tracking".

Eric,
I typically don't use a laptop when I image so APCC won't be of any help. Is what Christopher said true? Can thisIt requires some sort of computer to setup the CP4 and monitor the mount position as you would have to send commands to the CP4. If the CP4 does not receive any commands for a certain period of time the mount can stop tracking and park itself in place. There are soft limits that can be setup but there's a lot of complexity in getting the commands right. If you sync/recal/unlock clutches+move scope then the limits need to be reprogrammed. -Ray Gralak Author of APCC (Astro-Physics Command Center): https://www.astro-physics.com/apcc-pro Author of PEMPro V3: https://www.ccdware.com Author of Astro-Physics V2 ASCOM Driver: https://www.siriusimaging.com/apdriver -----Original Message----- |

See page 41 in https://astro-physics.info/tech_support/mounts/keypad/keypad-manual.pdf Does this meet your needs? Bryan |

Thanks for the info Ray, having a PC connected initially wouldn't be a problem and I very rarely unlock the clutches. If it needs to be reprogrammed after every sync that sounds like it could be a pain, that is something I frequently do.
Bryan the safe zones on page 41 are what I was hoping would be available, but it looks like this only protects against a slew command putting it in an unwanted spot. It sounds like it does not offer protection for standard tracking and doesn't accept values past the meridian. |

What is your use case where you would potentially leave the mount tracking? -Ray Gralak Author of APCC (Astro-Physics Command Center): https://www.astro-physics.com/apcc-pro Author of PEMPro V3: https://www.ccdware.com Author of Astro-Physics V2 ASCOM Driver: https://www.siriusimaging.com/apdriver -----Original Message----- |
