Hi all
Here is my first astropixelprocessor stacked and combined image. Thanks to all the information available on this forum that made this image possible
It was a tricky image to process mainly due to me checking image rotation on my Atik 460ex on some sessions to match the last subs but then forgetting to uncheck it leaving me with the challenge of matching rotated calibration frames with the correct subs!
thanks for looking
Bryan
That is a stunning image! Can you tell us more about the telescope and camera used and what subs you took exactly?
Wouter
Very nice! You shouldn't have to worry about rotation I think, APP will register them properly.

Thanks Wouter for your kind words
The camera is an Atik 460ex cooled to around -11c
The telescope is a Revelation Astro ED100 fl 600mm f6 doublet
the filters are 1.25mm astrodon 5nm
the mount is a skywatcher azeq6 on a self built pier
The subs are all 20min long and there is 31 Ha and 25 Oiii I used 50 flats, 40 darks and 100 bias
Cheers

Hi Vincent
Thanks for the comment
I was worried as I had taken Images before and after a meridian flip, but after a flip the flip I ticked a box to rotate the camera 180° to help me align the previous frame, sometimes I forgot to uncheck the box which meant the hot pixels and a column defect the camera has where now flipped even though the actual nebula was rotated the same way as the subs before the meridian flip.
therefore I needed to take calibration subs in the flipped orientation too and apply them only to the relevant subs!
I hope this makes sense
Cheers

That also shouldn't be a problem. 🙂 APP will register all just fine and if not, you can check a box to indicate some subs may be upside down.

Hi Vincent, thanks for your reply.
I am keen to know where this box is? To be honest, I haven't looked to find it yet and it's probably obvious, but if you could point me in the right direction that would be great!
Many thanks
Bryan
Here you go, but try it first without and just load all in, I think that should work fine;
