Forgive me if this is obvious somewhere but I haven't seen it. One of the standard outputs of a plate solution is the image scale. Is this displayed somewhere by SharpCap after plate solving? This is useful in calculating your exact focal length.
Thanks.
Does plate solving display the image scale somewhere?

Re: Does plate solving display the image scale somewhere?
Hi,
yes, this is shown in a notification (green message bar at the top of the screen) if you run the 'plate solve only' tool from the tools menu. Oddly it's not included if you use the plate solve and resync tool or the 'locate me' button on the telescope controls. I must fix that
In either case, you will find the information in the log
cheers,
Robin

Thank you, Robin. It would be nice if it showed the image scale in arcseconds/pixel and your focal length if SharpCap knows your pixel size.

Re: Does plate solving display the image scale somewhere?
Just to add to the conversation here, SharpCap does log the image scale as it's performing the plate solve. I've used this in the past to calculate the working focal length of my optical train.
It can be found just before log entries indicating that the field was successfully solved. Here's an example from my own logs (pixel scale 0.712663 arcsec/pix). I used the "solve and sync" or "locate me" button under Telescope Controls in the Camera Control Panel.
