Hi all

first APP HA OIII combination no layers ha lum 40%

 

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?

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 

Bryan

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 

Bryan

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;
