Have a general question regarding when SGP performs an Auto Meridian Flip…
I use a 10" newt on an NEQ6 Pro and a QHY8L. I always use the manual rotator option so SGP can get me to
rotate my camera to match the angle I choose in the F & M wizard. Also, I have the ±180 degree option set in
the sequencers Target Settings for rotation.
The QHY8L always produces some amp glow in the upper left hand corner of the Lights which needs to be sorted with Dark subtraction though. I chose M81 & M82 last time I was able to get out, the first image had M81 to the left of the image and M82 to the right with the familiar amp glow in the top left.
When SGP needed to do the flip it done it all fine except one issue. It didn’t get me to rotate the camera by 180 degree’s after the flip. When the next image came in M81 and M82 were on opposite sides and by the end of the run I had a set of images half of which needed to be flipped by 180 degree’s. What I noticed then is that I had amp glow in both the opposing corners once the images after the flip were rotated by 180 degree’s…
Now I know that using the ±180 option avoids having to take 2 different sets of Flats and a rotation wont be performed after a flip but when I do the Darks, these will only have amp glow in one corner, whereas, due to the flip and no 180 degree camera rotation,I have ‘X’ amount of amp glow in 2 opposing corners on the Lights ! ! !
‘IF’ I had to resort to the ‘Always’ option and take 2 different sets of Flats, how on earth would I manage this, haven’t got a clue to be completely honest !
Anyone got any advice on how best to approach this problem ???
