Hi, I took more data on NA nebula. Oiii and sii.

I loaded all frames from Ha panel one into hydrogen alpha, and l frames from Ha panel 2 under custom and typed in hydrogen alpha-2, same with other 2 channels.

Loaded darks, flats and dark flats and hit normalize. 

 

Many frames didn't register... some were panel 1 and some panel 2, so not sure what went wrong....should I load all Ha into Ha even if they are 2 panels?

 

I assumed I had to register all frames together...regardless of 2 panels. 

 

Please help!

Adam

Hi Adam @singding,

No, you need to load all H-alpha frames of all panels as H-alpha. You shouldn't assign a different channel name for H-alpha of another panel. It's all H-alpha 😉

So you are trying to make a multi-channel mosaic right?

What settings did you use in 3) and 4) ? And how many stars were detected in your frames?

For a mosaic registration you need a bit different settings than the defaults, so let me know what settings you used and then I can give you some pointers.

So it's a 2 channel "mosaic" or integration with 10% overlap. Ha  oui, and sii.

 

So I shouldn't make each channel and each panel a separate integration then and then integrate the panels after?

I tried the  recommended settings, lowered kappa all the way, upped the start and stop?

I apologize I can't access the computer now, but I did try a few settings.

 

When I did my hargb, I did each panel separate,  then combined them after....

 

Hope this helps for now. Basically registration failed for many frames that appeared ok..500 to 800 stars I think
