On 4 September, 9 September and 13 September 2023 weather has been promising. I took my stuff outside on all evenings for to capture Saturn, Jupiter and the Moon with my new highspeed camera QHY5III715C. On the first occasion I tried to image through the 85/510 APO refractor with and without eyepiece projection. This worked surprisingly well.
On the second occasion I tried again with the camera on my MAK 150/1800mm. It was a bit of very frustrating as the seeing had been very bad on all nights. No really good images came out.
I also checked the collimation of my MAK, but it only needed to be adjusted just a little bit. The collimation procedure is easy now with this high resolution camera.
Saturn in very bad seeing conditions. Only for short moments the Cassini division could be seen in some frames.
But even those frames were unusable, because the planet's image was totally bent.

Trying Jupiter in the refractor. Still only 10 degrees above horizon.

Trying on the Moon with high magnification and the APO refractor
4 September 2023 - 2138 UT - 150/200 frames - QHY5III715C - APO 85/510 + eyepiece projection - size reduced
Trying on the Moon full frame on the APO refractor, but size reduced and no projection.
The image has an astonishing resolution for such a tiny refractor.

VGA size (480*640 pixels) crop from the image above shows the real quality of the image and the system.
