Hi Eric,

thanks for that - the log looks like it has the information I need. I am away at the moment, but will go through the code later in the week to try to understand why it is happening and what to do about it.

cheers,

Hi Eric, interesting - I think that the message and the yes/no choice was coming from your ASCOM driver, since that SharpCap doesn't contain a message that asks you to confirm a meridian flip. Fron SharpCap's point of view, nothing really went wrong until about 1:24 when PHD2 lost guiding and could ...

Hi, well, that log didn't seem to have the constant drift in the solve co-ordinates during the periods when SharpCap was waiting for you to move on to the next stage, so I think something must have been working better. It's perfectly OK to run the polar alignment with tracking turned off - you are a...

Hi, no worries - I have made some code changes to allow the new idea to be tested out in the next version subject to using a command line parameter to enable it. We had some clear skies and a crescent moon last night, so I tested feature tracking calibration against the moon. I was using 1800mm foca...

Hi Eric, I've had one other report of this issue, but so far have not managed to get to the bottom of it (I can't break it in my testing). To dig further into this, I'd need a SharpCap log of the camera being opened with the following options in the 'Logging' settings ticked before opening the camer...

Hi, to be honest, I think that all consumer webcams are probably going to limit you to about 1/16s exposure, as they are designed for live video imaging rather than longer exposures. The closest I can suggest is to look at 'board cameras' - not a consumer grade webcam, but from the PC point of view ...

Hi Thomas, anything intermittent like this might be down to issues with USB communication between the camera and the computer. As a first set of troubleshooting , try the steps outlined in the 'Troubleshooting USB issues' guide - see https://forums.sharpcap.co.uk/viewtopic.php?f=18&t=349&p=1...

Hi Geoff, I think that your analysis is spot on - this looks exactly like periodic error in RA movement (and the direction matches up with the orientation of the camera). The lack of any significant drift in the dec direction and no signifiacant rotation indicates that your polar alignment is pretty...

Hi Bill,

good to hear that the graphics driver update did the trick! I will know what to suggest if the problem comes up again now

cheers and clear skies!

Hi Brian,

a very cool image - thanks for sharing. There are actually enough stars visible in it to plate solve the image (I tried on just the right hand side to exclude the zoom box on the comet and it worked!)

cheers,

Robin
