Projecting APCC Meridian Limits on a plantetarium program
|
Rick Darden
Hi All,
Sure would be nice to be able to show my custom meridian limits I created in APCC onto a planetarium program such as Stellarium or Carte Du Ciel. Is that possible or is there another way for me to see if a potential target is inside or outside a limit before I slew there? For example, if I select a target in the East, I want to know before I slew if it would slew with the mount on the West side/CW down or with the mount on the East side/CW up. Is there anything that will give me this info? Rick |

What you are looking for does not currently exist. In theory, a plugin for Stellarium could be made that reads a .pnt file and draws the necessary polygons in the sky, or adds an endpoint to Stellarium's API that APCC could emit the data into; but that's just a back-of-napkin hunch.

Hi Rick.
You can export the Horizon limits from APCC and import them in to Planetarium software like Cartes du Ciel, but not aware of any that can show Meridian Limits. Andrew J |

Can the meridian limits act like horizon limits, possibly with some massaging of the data?

Sure, one can take an hour angle and declination and map it to an altitude and azimuth and, with some interpolation, generate a "horizon" file that will have a horizon with an opening the shape of the meridian limit from which it was derived from. A neat hack to co-opt existing facilities, but a hack nonetheless.

Disregard. Now I understand.
Apologies for digital chaff... Bryan |

The reason I asked this question is due to having a potential cable snag if I slew to the East in the normal CW down position. It is at a remote observatory and I can't fix it for another few months. But, using the opportunity limits of an APCC median map gives me access to most of the sky with this problem. I just need to know where an object lies with regard to my Eastern limit and then I'm good to go.
I think having the ability to see your meridian limits projected onto any type of sky view application would be a useful tool.

Since we have the .mlm file created by APCC for the meridian limits, for those using NINA (and Yes, I think a lot of us have moved that way. I know I won't look back) it seems a simple NINA plugin could integrated this data into the sky atlas and other NINA features.

The Sky Atlas in NINA isn't set up internally to be extended by plugins. Despite the idea appearing to be simple, a lot of work would first need to be done to make it possible. Perhaps in the future but, for now, this first iteration of plugins was designed for extending sequencer functionality.
