Re: Vertical band on image
Hi Nicola.
?
The bright bands on either side of the frame are normal for a KAF 8300 sensor in the QSI683, with the brightest band always on the left side, but they will calibrate out perfectly when you subtract a master bias frame from your master dark, master flat and the lights before calibrating the lights with the now bias-subtracted master dark and master flat.
?
If you are not using a master bias frame this is possibly the reason that you can't remove that glow from the left side, if you are using a master bias as described above then possibly your calibration sequence is not correct.
?
In the screen shot below are a master bias frame from a QSI683 on the left, 600 seconds master dark in the middle and a PixelMath subtraction (Master Dark - Master Bias) on the right. You can see that when the master bias is subtracted from the master dark that the bright bands on either side of the frame are removed.
?
In theory, the bias component is included with the dark frame and should be removed from the light when the two are subtracted but my experience with this camera is that the edge glow is not linear and does not scale with the dark frame.
?
Try creating a master bias at bin 2x2 and subtract the master bias from your master dark, master flat and the lights before going on to calibrate the bias subtracted lights with the bias subtracted dark and bias subtracted flat.
?
The other thing I noticed in your image are the vertical column defects, these should have calibrated out of the frame when you subtracted the master dark but are still visible so is the image you posted a raw frame straight from the camera, in which case the edge glow at the left and right side are normal, or is the image dark subtracted, in which case the calibration process is not working or the calibration frames are incompatible.
?
Check also that the camera cooling is working effectively, partial bright column defects like those in your image are a characteristic of a KAF8300 sensor that is not cooled.

Re: New QSI driver- released 8/5/24
Hello Barry,
?
We (QSI/Atik) had to change to supporting just the ASCOM driver to make support more manageable as there were so many different astro programs out there. I can certainly talk with our software team about the possibilities for a 64 bit X2 driver. The QSI Cameras ASCOM plugin does now work in the 64 bit TSX.
?
I hope this helps
?
Thanks
Vince

Thank you for your consideration Vince. I will share with you that there has been a lot of “noise” on this issue in the many forums I participate in. The ASCOM driver has limitations, such as the one I described in my earlier post.?
A 64 bit X2 driver would go a long way for you guys as you continue with the QSI brand.?

Re: New QSI driver- released 8/5/24
Hello Nicola,
?
I am sorry to say we haven't been able to support the 500 series camera for several years now, but they are such a well made camera that they go on for years!? Sadly they don't share the same electronics used in the 600 series. We will, of course, always help where possible.

Re: New QSI driver- released 8/5/24
Hi Vince,
this message is a bit provocative. On the face of it, it looks as though you only support Windows now, while my old 500-series camera worked perfectly well under macOS running TheSkyX. I’ve now moved it another scope where it’s running under KStars/Ekos running on a Raspberry Pi.
I looked at your website and in fact you do offer a bit more than just ASCOM: you offer an API and a shared library under Linux. But it’s not said if the LINUX code runs only on x86 processors or if it also runs on ARM processors (such as the Raspberry-Pi)
And although KStars/Ekos runs on macOS as well as Linux, there’s no mention of macOS at all on your website.
This is a pity and will oblige me to find a different camera vendor when it’s time to replace the old QSI.
Cheers, Richard
BTW, you should remove the subtitle on the web page for Drivers and Software. It currently says “Comprehensive Software Support” which it clearly isn’t, since there’s no support for a widely used platform (macOS)

Re: Vertical band on image
Paul,
I do have the dark frame with the same band, taken at the same temp and same binning. But still, it?doesn't get rid of that and I don't understand why

It looks like you have an issue with your master dark frame.
The master dark should be produced from individual darks at the same temperature and exposure time as well as gain, binning etc, as the light.
Hi Paul,
unfortunately calibrating the frame does not help, the band is still there.

Take darks and this will be removed.
Due to other limitations of 2x2, I think you would be better off binning 1x1.
Dear All,
I own a QSI683wsg with astrodon filters on a GSO RC10 Truss. Recently, imaging in bin2 I am getting a vertical bright band on the left of the image which obliges me to crop it to work on the image. This band is not present when imaging in bin1.
I attach a highly?stretched raw image to show you the result.
Any ideas about its origin and how to fix it? Should I just live with it and cropping or stop using bin 2 at all?
Thanks for your help

Re: New QSI driver- released 8/5/24
Hi Vince,
does it mean that if the camera will eventually fail I can simply throw it in the trash bin with no chance of repair?

Thank you for your response. I should have been more specific with my objectives.?

I am using my QSI 600 series camera with TSX and FM5. FM5 has the ability to change the Readout Mode to improve the download speed when focusing. When complete, it switches it back to whatever it was before. Presumably the High imaging quality selection.
?
Many users are stuck using the 32bit version of TSX because the ASCOM driver does not operate the same way the X2 driver works for QSI cameras.?

Will this new driver accommodate the process I have noted above and secondly, are there any plans of introducing a 64bit X2 driver?
