hi crw4096,
have the same guide camera, different mount. For me this worked:
- Increase Guide Tab -> Options -> Pulse to 4000
- Do not check Subframe for Calibration
- Choose a bright star
Otherwise follow these advices (from:
www.indilib.org/about/ekos/guide-module.html):
Calibration can fail for a variety of reasons. To improve chances of success, try the following tips:
- Better Polar Alignment: This is critical to the success of any astrophotography session. Perform a quick polar alignment with a polar scope (if available) or by using Ekos Polar Alignment procedure in the Align module.
- Set binning to 2x2: Binning improves SNR and is often very important to the success of the calibration and guiding procedures.
- Prefer use ST4 cable between guide-camera and mount over using mount pulse commands.
- Select different filter (e.g. High contrast) and see if that makes a difference to bring down the noise.
- Smaller Square Size.
- Take dark frames to reduce noise.
- Play with DEC Proportional Gain or disable DEC control completely and see the difference.
- Leave algorithm to default value (Smart)
