Hi guys. I have 10 hours worth of data split into 4 sessions. Two sessions with Bayer Drizzle and two without. I also want to separate Ha and OIII to combine as HOO. How would I go about doing this?
Thanks.
Mm, the drizzling will sharpen the result, given the data is suited for that (undersampled and nicely dithered with enough frames). It will also increase the noise a bit. The other sessions will then be less sharp, combining that will likely produce a worse result then (better compared to only combining with non dithered data, worse when combining just drizzled data). Dimensions will be different, so it needs to re-register etc.
Separating Ha and OIII can be done when you load in the data and selecting the (extract Ha, or OIII) algortithm in tab 0.
OK thanks. So if I don't Bayer Drizzle on either would there be any benefit from uping the scale only?
Uhm, I would say no as there is no extra information present to make that beneficial, but I've never done it so I'm not 100% sure. It increases resolution, but I doubt it gives you a better result.
