How to restore operation after safety limit is reached?
|
Simple question but I have not been able to find the answer anywhere in the various documents I have read. If I slew or track into a safety limit, the mount beeps and stops tracking. Afterwards, it will still respond to manual slew commands from the HC to (for example) move away from the safety limit but will not perform a GOTO from the HC or the PC until I power cycle the Gemini2 and re-align.
Is this normal behavior or is there a simpler way to restore operation without the need for another align or synch? If so, I have not found it yet. TIA, Paul -- Paul Goelz Rochester Hills, MI USA pgoelz@... www.pgoelz.com |

Dear Paul, Try this (it has worked for me using Gemini-1...you can try in the daytime to test it): 1. Tell the mount to Park at CWD.? This will stop tracking, but not lose your alignment info.? Do not power off! 2. Then tell it to Start Tracking.?? 3. Then do a GoTo.? You should be back in business. This also gets me out if trouble when I don't know which direction?to press to get away from the limit position. Last point: there is a nice checkbox in to "move away from limit when limit is reached".? I suggest you try enabling that feature in .?

I suggest you try enabling that feature in gemini.net <>.Thanks, I had not looked that deeply into the ASCOM driver settings. The ASCOM driver did not have safety limits set so I duplicated the limits I currently have set set in the mount and also checked the "nudge away from safety limit" checkbox. EAST 100 WEST 123 WESTERN GOTO LIMIT 30 Does that all look correct? My east and west safety limits are tested and valid and have been set in the Gemini2 controller for a while now. The western GOTO limit is set so I will always have at least two hours of tracking available after a GOTO. Meridian flips occur 3 degrees past the meridian. FWIW, I had an incident the other day where the mount suddenly returned "object unreachable" in response to a GOTO after some hours of successful tracking. It then refused to perform any GOTOs until I power cycled and re-alined. Is it possible that it tracked into the west safety limit and didn't notify me at the PC because the safety limits were not set in the ASCOM driver (they WERE set in the mount)? If it beeped I could not hear it since I was indoors. So to recap, if I hit a safety limit I merely park, then un-park and perform a GOTO to any object? When the incident above happened, I THINK I tried that sequence before I powered off but I can't swear to it. Thanks, Paul -- Paul Goelz Rochester Hills, MI USA pgoelz@... www.pgoelz.com |

I think you are seeing the default settings there Paul.
But if you are ever in doubt, you can go back to square one with When I was getting started, and things seemed off to me, I would do a factory reset to get back to Zero and start over. Just do NOT do a formatting! You can recover from it, but it's not easy. I used this Video to set mine.? It's a little tricky (or I thought so at first) but here Ya go. I did the "Set Limit Here" a few times during my No Meridian Flip test run. I don't know if any other mount has this No Flip capability, but it's golden for me. An additional reason I got the RAEXT for my 811 mount. First was being able to configure my mount to my desired needs. But the No Meridian Flip is just genius to me. Meridian Flips have always been a PITA to me. And completely disruptive to my imaging. (In Fact, I have page bookmarked. It helps me, and it helps me help others.) Edit in: Sorry folks for this edit. But setting the limits is, to me, a fairly personal need based on each configuration. I use a fairly small, fairly short, refractor for Deep Space Objects. So my limits can be pushed as needed do to the additional room my telescope allows, and my mounts configuration as a "Portable Pier" (no legs to dodge). So in my opinion, each operator needs to address your personal needs, and to do so before your first use. It's prudent to learn as much as you can before you have a close call. ;^) -- SonnyE (I suggest viewed in full screen) |

The one big change was that I increased the western goto limit from the default 2.5 degrees to 30 degrees so the mount would do a flip if a GOTO caused it to slew more than 3 degrees west of the meridian. With these limits, it is my understanding that any GOTO will end with at least 30 degrees (two hours) of tracking available before hitting the western safety limit. So as long as I don't track for more than two hours before the next GOTO I should be good. At least I think I am ;) Paul -- Paul Goelz Rochester Hills, MI USA pgoelz@... www.pgoelz.com |

Russ,?
The extension should allow greater clearance between your scope and the mount, and meridian flips would not be affected. If anything you should be able to widen your safety limits a tad after checking balance and seeing where collision points might occur. I tried NINA for a few nights and the flips worked fine, and I liked the super fast platesolving with ASTAP. But I did not like the fact that you could not abort a sequence or modify targets and other info while running. Also when the guiding goes off due to bad seeing, clouds or other issues, NINA just keeps collecting bad data. Last I heard they were working on these issues and more updates were pending. Clear skies are a precious commodity for me so fiddling with a unfinished app is just not for me. But it's free and they are improving as it goes, so I might try it again next year. But I am so used to all the features in Sequence Generator Pro, changing to something else...¡ |
