I can share with you later the resulting stacks of an M33. L, R, G, B and some Ha. Let me know if you're interested in the stacks only and if you want me to align them too. There's no magic behind stacking separate mono subs and colour ones.

I used them for this: https://www.astrobin.com/313011/

I'm afraid I can't easily share ~12GB of data. However, there's not much you can do different about calibration, stacking.

I can help, here's a link to a zip file with some raw data for the Outer Limits Galaxy (NGC891) - https://www.dropbox.com/s/qx0oer35zup1zr2/outer_limits.zip?dl=0  (400MB)

I've already calibrated and integrated the flats, darks and bias since it's way too much data to upload otherwise, but you've got all the raw L, R, G and B lights in there.  Everything should be self-explanatory.  Not enough data really, needed at least another night, and I kind of got bored with the target and went off nebula hunting instead, but you should be able to make something of it.  Probably some coma in there too which I've since fixed, but it's a small target so should easily crop away.  Equipment used is as per my sig.

Nothing dodgy in that zip file, I promise !  Please let me know once you've downloaded it, because I want to remove it from my Dropbox.

You can use the data as you wish, on two conditions:

- if you publish it anywhere, credit me for the image capture

- you send me a hi-res xisf or tiff of your final work for me to publish if I want (I'll credit you for the processing if I do)

 

Cheers, and have fun,

 

Stuart
