Tried HAC125 on the Squid.
Despite replacing the camera mount, the sensor tilt remained. Maybe it needs collimation too. In one corner, the stars are sausages, in the other, donuts.
The Squid appeared somewhat faintly, everything is drowning in noise.
Seems like the idea of shooting faint deep-sky with an uncooled camera is not such a great idea...

It seems like the idea of shooting faint deep-sky objects with an uncooled camera isn't the best...
Such faint objects are more likely in the red zone; you can still manage in winter, but in summer you have white nights, so it doesn't really matter whether it's cooled or not.

Well, there are still about 6 hours of darkness left. A bit earlier, I shot this same object with the 2600Air using a dual-band filter and a quad. With the dual-band filter on the 2600, the Squid Nebula shows up a bit better.

Then the bits are to blame for everything, the difference between 12 and 16 is big and the dynamic range is different.

This combination turned out quite well. Just need to align the field...

Because the Rosette Nebula is so bright overall, the contrast is overwhelming, and here the Squid Nebula is almost invisible.

From my balcony, the Rosette Nebula is no longer visible, so I have to experiment in the Cat's Paw... Squid Nebula.
