Help please- Flat Issues
« on: 2017 March 07 13:27:17 »
All of a sudden, my Green and Blue flats are not taking out the motes or vignetting.  I've had ZERO issues, but made several updates to my camera driver and am thinking it's a software problem.  I've ran it BPP and integration/calibration separately to no avail. 

Here are my files: https://www.dropbox.com/s/4lnq1f6y15zf454/16200Help.zip?dl=0

Also, I'm on a WO 132 refractor with a QHY 16200A camera.  I capture with SGP and calibrate with Pixinsight.  It's been flawless up until this month.  Kinda scratching my head at this point so any help would be GREATLY appreciated.

did you get new bias/darks after the camera firmware update?

Whatever this is, it just started.  I've had zero issues. 

I'm really just trying to see if I've got a corrupted piece of software of if my flats are messed up. I have a flip flat and the calibration setup has been run with 25k ADU flats.  I re ran it at 35k and it's the same deal. Dust mites in the B & G channels.  The L and HA are fine.

well what happens if you get new lights? dust does move/settle/appear from time to time.

Well, I mean, the motes do disappear after LRGB combination, but it's either overcorrecting or under correcting and I'm just confused as to why that would be.  Q hasn't responded as to whether it could be a driver issue in terms of gain/offset settings in the driver.
