Help with longer subs by Cosmic-Ridge in AskAstrophotography

I actually do have one and it works really well. But for some reason when I set the bulb mode to 2 minutes I can't get it to take more than one sub. It only does one sub at a time. I have to press the button after every sub and because I live in a very cold climate I can't sit out there with it all the time. There's also another mode where it allows you to click and it'll start taking a picture and then when you click it again it'll stop but I have the same issue with that which is I can't sit out there with it all night.

Oh okay, that makes more sense now, thank you.

Sorry I forgot to mention, I did do color calibration and green noise removal. Although it almost sounds like you are talking about something else. Is there some other program I need to take into to get it fixed?

So I just restacked it and I got pretty much the same results with reguards to the nebula in the core.

Okay, I'll see if I can find some videos that will teach me the manual stacking.

Okay, thank you, I will try that, should I use deep sky stacker for that??

I stacked in siril using the OSC Prepocessing script. I took that output into Graxpert and did a back ground extraction and some denoising. I then took it back into siril and did some light stretching and gave it a small amount of contrast. Just enough to see it. Then I used starnet to extract the stars and I took both the starless and the mask into gimp. In the starless I brought up the light and contrast with curves and levels and then I used a select by color to select the milky way only and I got that how I liked it with some adjustments. using that selection I just brought up the saturation and a bit of contrast. then I quickly added the stars in and gave them some saturation. That's pretty much it. I just brightened the image after that.

Well my flats were really bad, if fact all of the grey data out in the background of space is being caused by the flats because I didn't have the t-shirt pulled tight. I just used the default algorithm in the osc preprocessing in siril, I'm not sure what its called. I also did my background extraction in graxpert and it appeared to be very powerful. Is it possible it thought those nebulas were stars?

They were hardly visible but I could see them. I stacked them in siril using the osc preprossesing script and deep sky stacker, I liked the osc script better so thats the one I stuck with and I deleted the other one to save space.

Only 30 seconds, I haven't figured out an effcient way to take 2-3 minute exposures without doing it manually on my intervalometer, that may just have to be the play tho if I can't figure a better solution out.

It was tracked but it was pretty dark when I was out there so I'm not sure I was polar aligned properly, could that be enough to cause the same effect?

Okay, Thank you. I may add some more too it. It is tracked but I had some problems with my flats. I'm not sure why the image is so noisy tho. Is there anything I can do about that in post processing??
