SharpCap Forums

Hi Nikko,

you are quite correct - the code is there to add and also retrieve the gains of interest, but due to a bug they are only actually used if SharpCap thinks the camera has a gain control that is linear (ie 100 = minimum gain, 200 = 2x gain, etc). I have now corrected this and the change will be in next week's update.

The saving of the gains actually is preserved as long as the camera is plugged in - if you unplug and then replug they will reset (as well as if you close and reopen SharpCap).

cheers,

Robin

Thank you, Robin! And thanks for the clarification.

Have a good weekend!

For cameras like the Altair series is there any way to get the Sensor Analysis to only run in HCG mode ? It's not always easy to find the conversion factors these camera use and trying to translate the SharpCap values to APT / NINA can be tricky.

Hi,

you would need to use the ASCOM driver for that - in the ASCOM driver you can choose the mode between LCG, HCG and Auto. SharpCap's native code for Altair always runs the camera in Auto switch between LCG and HCG.

That's great, thank you. I assume there is no downside to running the analysis using the ASCOM rather than native drivers ?

Hi,

the downside is that because ASCOM doesn't make the black level (offset) control available to SharpCap directly, all the tests will be done at the black level you set up in the ASCOM driver settings. When you use the native driver it will try a range of black level values and record data about them in the results. I'm not sure whether NINA cares about that info or not.

cheers,

Robin
