Hi, hopefully someone who uses the AM5 can give you more details, but in outline... * Connect mount to PC/laptop with USB cable. * Make sure ASCOM platform (latest version installed) * Install ZWO ASCOM driver from here : https://www.zwoastro.com/software/ * Tell SharpCap that you would like it to u...

Hi Matt,

glad you like it - if you haven't already give the automatic alignment a try... It tends to work really well (sometimes slightly over-exposing for the auto alignment helps)

cheers,

Hi, it's a bit hard to tell what is going on from the screenshots. If you tick the 'Log' checkbox on the histogram then it alters the horizontal scale to be logarithmic, giving more space to the important part on the left hand side. That helps a lot when manually adjusting and seeing what is going o...

Hi, I would suggest opening the camera with the <CTRL> key pressed to stop it from reloading previously saved settings - I can see from your capture settings file that you had some odd things enabled including somewhat strange display stretch settings that mean anything below 50% image brightness wo...

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 ...
