Wow!!! I've just bought AP after watching your vids, and I'm blown away of your skills. You have teached me so much in PI, and I hope you make more vids on AP. You make more diffrence than the change form my sony a7R unguided to the ASI2600 MC Duo...
I wonder if you could clarify one thing: can I also apply these techniques to OSC images from a DLSR, or shooting with filters is a prequisite? if filters are a requirement, I'm really looking forward for future video addressing OSC data! thank you so much for this channel, I love your content, and the techniques you teach are extremely interesting!
You can absolutely use this method with OSC data (and Narrow Band). The only difference is you would not have a luminance channel so you can skip the first part of the process in which luminance is screen composited to RGB.
Thanks for your videos. Very informative as I'm just starting in AP. Do you have a video on keeping/enhancing star color? I'm in a minority here, but I love the open and globular clusters. I'd like to present them close to what I might see visually in a good scope.
I haven't done many videos yet on specifically processing star clusters. In general, the hardest thing about processing them is the unusual artifacts they create that I call light worms. I did a video on removing them, that I'll link below. In general, when processing star clusters, you just stack your subs and push up your saturation bar on your curves tool to emphasize color a bit. It is necessary to monitor your luminance channel on the curves tool to tone down core brightness so it doesn't drown out the dimmer outer regions. In some cases, you may want to break up a star cluster into luminance zones (see my video on processing M 106 for how to do that). ua-cam.com/video/DytWP2P9fx0/v-deo.htmlsi=Sm8xGHuA4JbcpHv_
It will work with data from an OSC. Since OSCs always have a Bayer layer in front, you can only get RGB information. However, all the information is there. You just composite your RGB information to fold the information back on itself and increase it. If you want more definition (contrast sans color), you can strip the high frequency information out of any layer with the frequency separation tool.
I am overwhelmed by this technique. I started and learned astrophotography signal processing in PS I have since purchased Pixinsight but always end up finishing my blending in PS. But nowhere near to the degree of what your techniques render.
It only gets to a little over 30 degrees here. I start shooting it when it's at 15 and go until dawn. But I live in a dark sky area, about Bortle 1.5 I think, and there is only the ocean and woods to the south, so no light pollution to contend with.
The moon is a broadband emitter, so what narrowband can accomplish for you when there is a full moon is limited. I tend to deal with the full moon by shooting on the opposite of the sky.

Thank you so much. AP is like a violin: a fair learning curve but worth the effort for the results it can produce.

@@SKYST0RY awesome! thank you so much for the quick reply!

@@SKYST0RY Thanks. I'll check it out, and try your suggestions.
Very nice! Does it also work with OSC camera, since the luminance is extracted from RGB?

Thank you! This will give me plenty of work between sessions 😊

Just keep at it. Practice and study. It's like learning music; one day all those seemingly unrelated bits of theory start to mesh together.
I'm in Wisconsin, and Eagle is at 30 degrees max. It must be lower for you.

Fullmoon ruins narrowband? Or just makes it a bit worse? For anewbie to practice narrowband though? Not your amazing images.
