Hello,
I'm not sure if I'm doing something wrong or if it's a bug, but when I try to solve this image:
https://imgur.com/a/OV8hcc6
SharpCap solve it this way: https://imgur.com/a/8DoR1Dk
Solution : RA=04:37:48,Dec=03:31:33S (J2000)
Field of View : 0,27x0,15 degrees
Time : Fri, 13 Nov 2020 22:46:15 GMT
Orientation : up is 330,2 degrees E of N
but the correct coordinates are:
Center (RA, hms): 04h 37m 48.006s
Center (Dec, dms): -03° 31' 33.352"

Any help is appreciated. Thanks.

Re: Plate Solve with negative Declination
Hi,
if you look closely, SharpCap is reporting the declination as
03:31:33S
Note the S at the end, which indicates South of the celestial equator. So effectively this is -03:31:33, just using N/S instead of +/-.
In SharpCap 3.3 I have changed this to use +/-.
cheers,
Robin

Sorry, still fighting with this issue.
This time the Dec is reported as N but it should be S instead:
Solution : RA=23:53:52,Dec=00:42:24N (J2000)
Field of View : 0,27x0,15 degrees
Time : Thu, 19 Nov 2020 12:04:16 GMT
Orientation : up is 329,2 degrees E of N

Hi,
can you send me a copy of the image that is causing the problem and also the full SharpCap log captured after the problems occurred – that should have lots of lines in it with information about the plate solve progress and results which will help me track down what is going wrong.

Re: Plate Solve with negative Declination
Hi,
thanks for the info – I've tracked it down to a problem reading the declination value from the plate solving output when the declination is between -1S and 0 degrees. If the declination is greater than 0° or anywhere less than -1° then the bug doesn't happen. I will be fixing this in SharpCap 3.3.
