Going up to 16 bits will store 12 bits faithfully, is not scaled in any way to fill 16 bits. The extra bits are just zeros.

Andrew replied to the topic 'Pi 4: Does 2 GB suffice?' in the forum. 4 days ago

I would recommend the 4GB model simply because it doesn't cost that much more and you never know when the extra ram can come in handy. But 2GB works, and already a very worthwhile step up from the Pi3 with only 1GB.

This got me thinking it would be neat if the align module displayed a refreshable overlay of a few star positions that correspond to a position and rotation to match a solved image or desired orientation in degrees.

I'm thinking manually matching 3 or 4 stars within small targets would get you pretty close.

Maybe it is reporting a trigger SIGNAL, for lack of a better TERM, for each axis, one for RA, and another for DEC?

You can set a guide scope focal length for the polemaster in the mount tab in EKOS as its own configuration preset.
That way just switch configuration and the fov should workout in the align module.

I suggest pairing it to the Pi at the mount where it is most likely to be used.
Install jstest-gtk to configure the joystick and calibrate the analog stick. The only quirk with it is saving the configuration does not work properly and requires a command in the terminal to save it permanently.

sudo jscal-store /dev/input/js0
By the way, joysticks have a bad habit of going to sleep. Whenever this happens you must stop and restart the Joystick INDI Driver after waking up the controller.

Andrew replied to the topic 'Dark frames and the 294' in the forum. 1 week ago

While I do not personally have experience with the 294 sensor, I have heard from a few fellow observers that that sensor has some issues with the cold finger not uniformly cooling the chip causing what appears as amp glow but. That may be better handled with flats. And also bias frames don't work well due to extra calibration pixels located on the perimeter of the chip and how they are processed internally. You may want to check cloudynights for camera specific discussions.

Andrew created a new topic ' Wish: Alignment - Slew to Target sync point cleanup.' in the forum. 2 weeks ago

When using the alignment module to center a target a lot of sync points can be generated in a small area. Each one carries a weight and can make it difficult for the mount to correct the remaining pointing error. My experience is with the EQMod Driver for SW HEQ5 Pro. Targeting might improve if sync points within the immediate vicinity get automatically deleted, say any old points 1°-2° apart.

Thoughts?

You can try clearing the alignment model when it starts behaving oddly.

Make sure the mount is unparked. And the 'Manual' option for PAA is unchecked.
Manual is for non-got mounts such as star adventurer, allowing you to manually rotate the RA for each step.
