Hi, this is an interesting one... I can't get it to happen myself, although thats probably not a surprise as it only affects one of your systems The extra calculations needed to put the histogram graph into logarithmic form are pretty minimal, so that's unlikely to be causing the issue. I can see th...

Hi, I have had a look at your log and I can see the drift in the data, happening over quite a short amount of time - 30s to 1 minute. The rotation of the earth is not going to have any significant effect over that sort of timescale with the setup you are using with your ASI120MM and a relatively sho...

Hi Eric, yes, I made that change in February, so it will be in the version that you were using. In this case the error seems to be coming from PHD - 'Cannot initiate guide while guide is in progress'. I suspect that the issue is something along the lines of * SharpCap checks PHD state - finds it is ...

Hi, you won't get the full frame rate if you open via the ASCOM Cameras options - ASCOM is really designed for deep sky and the way the camera is controlled via ASCOM means that the frame rate probably won't get much above 3 to 10 fps. If the device is showing up in the 'ZWO ASI Cameras' section of ...

Hi Matt, hopefully the cure for this is as simple as updating to the very latest version of SharpCap 4.1 from our downloads page (https://www.sharpcap.co.uk/sharpcap/downloads). Versions since 4.1.11974 have included an update from ZWO published in March that should add support for your camera. Olde...

Hi, OK, having thought about this a bit, I think I can see a way to remove all the uncertainty about how the mount reacts to the movement pulse in opposite directions. That would leave a possible remaining issue with delays to the apparent movement on screen due to backlash takeup, which could be de...

Hi,

I think they should work under tha ToupTek SDK, so with basically full support. I don't have any myself to test this, but have had reports of success from other users.

cheers,

Hi Jean-Francois, yes, the 'HasPlateSolveInfo' is just yes/no - if you want more then you can check the PixelPositionProvider which can map pixel co-ordinates to/from sky co-ordinates. The reset is only manual, so if you paste multiple times then the in-memory catalog will grow. Assuming you are onl...

Hi Jean-Francois, yes, your interpretation of the functions is basically correct - to clarify ReloadAllCatalogs - this reloads all the catalog data including the built in catalogs and any custom catalogs found on disk LoadTextAsCustom - this expects the catalog data to be in the string (not a filena...

Hi, there are two things that you need to check 1) There will be a red box on the image - this is the selection area that is being used to mark out the star to be measured. If that box is over background dark sky rather than a star then you need to move it. If you can't see the red selection box at ...
