ISO/gain reported as -1
I'm using a Canon 77D and record my subs using an ASIAir. When i load my fits files they are reported as iso/gain -1. The fits headers however do report the correct iso (800). When i load my Canon Raw files it works correct.
This is extra annoying because this value is also written in the filename of the master files. This way I don't know what iso the master files are created for.
Also see the attached image. I can also provide an example file if that helps the developers.
Strange, I'd like to have that subframe to check out if that's ok with you?
Go to https://upload.astropixelprocessor.com and use upload1 (or upload2 till 5) as username and password will then be the same as the username.
Create a directory named “svego-isoreporting” and upload in there. Thank you!
@vincent-mod I've just uploaded my file. Please let me know if i can do anything else to help.
I'll have a look at it asap (probably tomorrow as we're almost having dinner here 😉 ). Thanks for uploading!
Sorry, that was today then, bit busy down here.
So I see the issue I think; in the FITS header not only an ISO is reported, but also an EGAIN value of -1. I'm wondering if that is something you can check in your capture software as a Canon 77D doesn't have a gain.
@vincent-mod no problem for the delay.
I don't think there is a setting for an EGAIN value in the ASIair. I havent found it anyway.
A value of -1 seems like an invalid value.The software developer in me would probably ignore -1 values 😉
Yes, true, I'll mention that to Mabula. But it's also very strange for the ASI to write that in there. Would be nice to report that to them as well. 🙂
