| Summary | 0001851: Binning distortes image geometry | ||||
| Description | Setting binning to the highest value is useful for centering and detection. If I set binning from 1x1 to 4x4 and back to 1x1, both 1x1 images had a different image geometry. See attached logfile. Maybe INDI caused. Thomas | ||||
| Steps To Reproduce | Set Binning to 1x1, capture Set Binning to 4x4, capture Set Binning to 1x1, capture | ||||

Yes, the problem is in the ASI INDI driver. CCDciel do not touch the frame size when it change the binning because (contrary to ASCOM) the INDI frame size is always given in unbinned pixel. And setting the same camera size in the indi_simulator_ccd (4656x3520) do not show this problem. You can activate the driver debug to logfile in the INDI driver and ask in the Indi forum. I let the issue open for the case I can do something to help with the problem, as sending a CCD_FRAME_RESET when changing to 1x1 and frame is near of the full size, but I prefer if this can be done in the driver. |

Thanks for your reply, I will adress this issue in the INDI Forum, I am a user there. In CCDciel, I have realised pressing RESET in the Frame Tool solves this problem. But once forgotten, frames got unusable. |

Hello Patrick, Jasem fixed it very fast. Issue ist gone. You can change it to solved. Thomas http://indilib.org/forum/ccds-dslrs/2849-asi1600-changing-binning-results-in-false-image-geometry.html#21318 |
