39 mins Luminance
1hr 19 mins Ha
1 hr 19 mins OIII
1 hr 20 mins SII

I fixed my tacking issues and so out of 280 frames, I only lost 3. (If anyone who edits this has any tips or a good direction to point for a tutorial that works on Siril... pls)

Ngl, I have no idea what I'm doing

RGB?

#

the luminance is pretty much useless with narrowband, since theyre incompatible bandwidths and signal types

#

although, your data looks quite good, if i can sort the gradient out it should look great in SHO

Hi, I am not able to help you with Siril, but in Pix if you use any video explaining the process of working out an SHO image, your data its quite nice.

#

Here its only did a small crop, Channel combination SHO, Linear fit, I like to use background and color calibration method on SHO, BXT and NXT

#

#

this is the result, its not streetched yet.

#

and after removing the starts, its really clean

#

#

the gradient correction is poorly done, but this is so you have an idea how good the image can get

#

#

a fast rendition of what I could do.

Well, I just got the free trial of Pixinsight and roughly got an idea from yt tutorials as to how to edit it

#

I redid it from the beginning and didn't include the Luminance subs

#

It was coming out solid green until I realised that the Ha data also needed to be a luminance as well as the Green
