ha first long sub tests

[blink138]

hello members these are the first longish single subs i have trialled from suburban perth
although i have had the 12nm 2" filter for a while everything has conspired to go against a crack at it
the horse one single 20 min sub at iso 800 stretched a little in the hdr tool
tried something different with the rosette which was a single 15 min sub at 1600, again stretched a bit
i have had trouble getting the red channel histo onto the second block, it seems to just "spread out" when it gets closer to its goal?
any advice on the pic and the histo will be welcomed
regards
pat

oh yes the apm 107 and a 0.79 reducer

Nice image but you would see more Detail detail with a black and white image Red covers a lot

Try to use only the red Channel of RGB. It is b/w.
I stack the photos normally. In DSS. After this I open the Autosave.tiff and copy only the red channel.
I process this red channel - b/w - before use it again on Light RGB photo.
