Yes, Herrhausen, you are quite correct, however RMS values are still affected because of the shift in star position after dither. I do run dither settle for about 20 seconds or so, as my stars would appear egg shaped because of the residual movement of the guiding action after dither. I think what may need to happen is RMS values should be taken AFTER GUIDING SETTLE time. This would at least eliminate the RMS values from showing incorrectly high values.
I have noticed this as well, I have a minute settle after dithering and I still have this issue as well. It seems the guide star is off a little after dithering and the error goes into the RMS error no matter how long the guiding settle is.
Here are some notes about my experience with the new QHY - 268C
First off, the camera is amazing - 16BIT and very sensitive. APS-C. It is much longer than any other camera I have.
On KStars - EKOS - The default camera resolution is 6252 x 4176, this works well with focus module and capture module.
For some reason the Alignment module does not work in bin 1x1 mode it brings up a non-compliant resolution. BUT if you use 2x2 binning on the alignment module, it works well.
The INDI panel works well. I could change the Camera modes (there are 3 gain modes available).
Very happy with the camera, and very happy it does work with KSTARS with some workarounds, but I imaged all night without an issue.
If you have any questions, I will share my experiances.
I have several QHY, ZWO, CCD - Atik.
I try using my QHY 268c with Astroberry and KStars on Windows 10 and the camera seems to respond normally, I can set the temp, and I see the temp dropping, but when I take a picture, everything freezes on the camera interface.
It never downloads the image.
Is it because the camera is too new?
Let me know. Thanks.
Tweeb, I had to dump the cache on my browser for the version number to display properly. Not sure why, but it worked after I did that in Chrome.
Will I know that doesn't work for sure. The camera side will take a standard usb cable, I tried it in my RPI3B+ with the same result, however when I used a standard cable it worked great (not the cable that came with the camera)
Ok What kind of PI are you putting astroberry on? If you hare using a PI 3, then use a USB2 cable. I just tried using a USB3 cable on a USB2 port and that locked up my QHY183M. If I use a USB2 cable plugged in to the same Rasberry Pi 3, it worked just fine.
Try using a USB2 cable with your camera and see if it works.
Try sudo apt-get dist-upgrade. That may help.
My Atik 16200 camera can download a focus image, however when using the camera interface it looks like it takes am exposure, but then says exposure aborted right when it gets to download image.
I am using a RPI4, could that be the issue?
Trying to get this thing working.
I have been able to get from Astrel-Instruments the ASCOM drivers for the Camera / Filter (It has ver 2.7 KSTARS built in), however I don't know if I can use them with INDI-SERVER or Astroberry.
Anyone have any experience with this camera / filter?
