it disables the automatic image analysis and it disables the astrometry computation after each image.
- Pros: Save time during image acquisition.
- Cons: If something is going wrong then you have no possibility to check that the telescope is pointing in the right direction.
There is two setup can benefit from this option
- Very tiny telescope
- Excellent Mounts (10 Micron , Astrophysics) with medium size CCD (10mm by 10mm) and focal length below 3000mm, of course the telescope should not bent
“Astrometry with Pinpoint”
This the recommended option unless you are in one case described above.
After each image capture Astromatik checks with pinpoints and MaximDL methods that the image pass the quality control criteria.
When the mount tracking is perfect and the telescope has no coma, then all star are perfectly round and the flatness is zero. If the tracking is very good but your telescope has large coma errors then the flatness will be probably larger than 0.1. The measured flatness reflect the quality of your setup.
When the measured flatness is above the maximal flatness then Astromatik will take the image again until the star in the image as the expected flatness.
When you set a large value it disable this check.
Maximal pointing error
This parameter defines the tolerance between the expected telescope position ( the position of your target) and the current position of your telescope (the position that we get after plate solving). Every mount is not pointing perfectly, there are many cause why telescope are not pointing at the expected position.
- Magnitude Limit : Please select a magnitude limit that fit with your setup, if you use a setup with a large field of you then reduce value as much as possible
- Catalog: Please select a catalog and set the path.
Recenter after slew
when you take long exposure it makes sense to check that the scope is pointing on the target before the long exposure
