Question: Combining data from different cameras

[bmhjr]

I have some widefield data taken from 2 different cameras using the same lens.  The modified camera has higher resolution with smaller pixels but also is fairly noisy.  The non-modified camera has better overall sensitivity but lacks the Ha response.  I was wanting to try and combine the data for the best of both cameras.

I would most likely register the frames to the higher resolution modified camera.  I would like to try incorporate the better Ha response of this camera into the integration of the other stack.  Do I do this by using the Red channel and the NBLRGB script?  Do I need to make a combined luminance or something along those lines?

I have never attempted combining data like this and it may not even be feasible.  Does anyone have any suggestions on a good way to proceed?

Thanks

Bill,

Once you have registered both sets of data to a sub from the high resolution camera, you can treat all the data the same.

Before using the NBLRGB script, try just integrating all the data together, it may give the result you want. If that does not work out, integrate the set of subs with better Ha signal, extract the red channel. Then integrate all the subs from both cameras as I indicated at first, then use the NBLRGB script to add the red channel with the better Ha signal.

Thanks Mike,  I'll give it a try.
