I have a quick question concerning the processing of a Ha image. The moon has been full for the last few nights so I decided to give "Ha only" a shot...ASI 1600mm pro, 75 gain, 12 offset, 30 180" subs. Here's my question. The image is Ha only..no LRGB data. Do I process this image the same as a OSC image? I have the required darks, flats and bias frames.

Thanks,

Lynn

Lynn,

I have an ASI1600MM as well and regularly process Ha images with APP. I’d advise you to make sure that multi-channel processing is enabled in tab 1 and then to either use the filter keyword in the fits images (assuming you shot all of them with the Ha filter) or to manually assign them to the Hydrogen Alpha channel. From there it would be normal processing.

 

HTH, Wouter
