Object Framing in N.I.N.A lately has not aligned with other software/hardware. I Do Not use a caa. When I frame with nina vs asiair, stellarmate pro, voyager, I get a different sensor angle reading. Is this user error? Also does sharpcap have a way to check framing? If so i would appreciate any ideas.
N.I.N.A object framing sensor angle differs from other astronomy software
Plate solving should give you an accurate number. How much of a difference are you seeing? Do you get a different number when just running through ASTAP directly?
Well Written
Interesting.
Best would be to know via an example the reported degrees.
When I frame with NINA this goes from 0.00° to 359.59°
How do the other software report angles?
Maybe this has something to do with the programming where perhaps +180° is the same as -180° as it does not matter in the image as one can rotate it ¿? who knows. Just guessing.
Perhaps also something to do with a homing procedure.
I just made a test with one of my images using PixInsight
And it reports -90°, 0° and +90°. -90° was counterclockwise rotated and I expected to see 270° ¿? who knows¿?

During plate solve in nina the results always show upside down. The subs come in upside down as well. I should have clearish skies tonite and will record the degrees of rotation on nina and asiair.

Having recently gotten a Pegasus Astro Falcon Rotator (v2), I did discover that N.I.N.A. will consider angles that are opposite by 180 degrees (30 deg vs 210 deg, for example) to be equivalent, and will rotate to whichever of those two angles is closer to the current angle. So the images you capture at a given angle may appear to be upside down from what you expected.
My experience with N.I.N.A. has been very good in regards to the framing angle I specify.
Do note that N.I.N.A.’s angle-measuring convention is that the angle increases in a counter-clockwise direction. I know that Stellarium behaves opposite, increasing in the clockwise direction. I don’t know about other software.

If the rotation is accurate but 180 opposite, why does it matter? The same thing happens with a meridian flip.
Rotation shift after meridian flip (no electronic rotator)
Hello, I recently noticed that during my last two sessions of shooting that I experienced a shift in the field rotation after the meridian flip. All images taken before the meridian flip are same orientation and matches with framing assistant, and al...
