Re: Motion Detection

Hi, if you have a relatively plain background then maybe the 'seeing triggered capture' mode of the seeing monitor might help? See https://docs.sharpcap.co.uk/4.0/#!2!Seeing%20Monitor That functionality monitors the image for increases in contrast that are caused by periods of good seeing, but it mi...

Re: Histogram

Hi Louis, the top histogram is one from a camera in high bit depth mode (12, 14, 16 bits). That always shows a finer graph than a camera in 8 bit mode (which is the style of the bottom histogram). Also, your camera running in high bit depth mode is producing data that has missing values - that is so...

Re: No consigo grabar saturno

Hi, if your computer cannot save the images to disk/ssd fast enough to keep up with the camera then SharpCap will use memory to store as many images as it can to avoid them being lost. When you press 'Stop Capture', some images will still be stored in memory and need to be written to disk. This can ...

Re: Brain Fail

Hi, first you are using SharpCap 3.2 - the latest version of SharpCap is 4.0, which you can find on the downloads page. There have been lots of bug fixes between 3.2 and 4.0, including some with the measurement of sky brightness, so it would definitely be worth trying 4.0. What should happen is that...

Re: 64bit won't work on my older Xeon CPU

Hi, I've thought about trying to merge the two pools of memory, but it is critical to keep the frame cache from taking all the memory otherwise there may not be enough to process/display the frames, so you end up having to ring fence part of a combined pool anyway, which really means you haven't ach...

Re: SV305 gain issues

Hi, SVBony decided to change how they measured the gain values in a recent SDK update, which explains why the ranges have changed. Old way (SharpCap 3.2): Range was 1 to 30 1 was the minimum gain, gain 2 was 2x as bright as 1, gain 5 was 5x as bright as 1, gain 30 was 30x as bright... New way (Sharp...

Re: Sensor Analysis SV305 Camera

Hi, first, it's worth pointing out that recent versions of SharpCap install pre-measured sensor analysis data for both the SV305 and SV305-Pro cameras, so there is no real need to do your own measurement. If you do want to run the analysis then it sounds like you need to step back a bit and make sur...

Re: Installing AstroTortilla

Hi,

which version of AstroTortilla were you using? The latest I have installed is 0.8 alpha1, which seemed to work.

You could always try installing Ansvr or ASPS - basically the same solving engine with different installers.

cheers,

Robin

Re: PA with a dobsonian

Hi,

the most common cause of variation in the PA readings is any flex between the camera/scope being used for the alignment and the 'RA Axis' - loose dangling cables are quite enough to affect the reading. Worth considering this as a cause.

cheers,

Re: Plate solving can't find star index

Hi Joe,

What happens if you run Astap manually and try to solve an image - does that work?

cheers,
