4.1 : ASCOM Camera Driver - no Gain showing

#1

Post by MattTexas23 »

Using the 4.1.11 version (28 August 2023) - and the ASCOM Camera Driver (Canon T3i), I cant find the ISO/Gain settings anymore in the right hand window - see screen shot.

The new features (Gain Shift) seem to have dropped off. When I click on "Show" the ASCOM driver window pops up.

desired outcome; bring back ability to set ISO/Gain for ASCOM Camera Driver Camera in 4.1

thanks!

Tested this with my Canon 7D Mk2 against 4.1.11 version (28 August 2023) with ASCOM Platform 6.6 build 6.6.1.3673. For both 32 and 64-bit versions of SC, the Gain control in Camera Controls is missing. Gain is present with SC 4.0.95.38 32-bit.

Hi folks,

thanks for the report - I will test this. There is special handling for cameras with individual gains (ISO values, etc) rather than a slider like most cameras, and I suspect that has gone wrong.

cheers,

Robin

Hi,

this turns out to be a combination of a bug in ASCOM.DSLR (the collection of Gains it returns for the camera are not correct, according to the ASCOM specification) and the new ASCOM library I am using in SharpCap 4.1 not dealing with the issue without anyone noticing it.

It's not something I can fix in SharpCap itself, but I have raised issues with both the ASCOM team and the ASCOM.DSLR project - either fix would do the job, but the one from the ASCOM team would fix things for existing binary versions of ASCOM.DSLR rather than requiring everyone to get a new version fo that.

cheers,

Hi Robin,

I am trying to figure out what I need to do next to overcome this bug. I am not sure if it has been fixed in a released version of ASCOM by now - I read that the latest reply on the issue tracker on github was Oct 2023, but do not know how to interpret that.

Today I am using two versions of Sharpcap on an evening. Sharpcap 4.0 : where I can set the gains of my DSRL, so I can Polar Align. Sharpcap 4.1 if I want to Push to direction - but gain default is ISO 100 - and the window to change the gain settings is not showing on the right hand side, like reported. I run ASCOM 6.6 SP1 (6.6.1.3673).

Is it resolved, so I can update ASCOM and give it another shot?

thank you,

Matt
