Has anyone ever said they appreciate your narration voice? Well I do. The cadence and tone is just perfect, documentary'esque. Even if Im not able to watch, just listening is a treat.
The funny thing is sometimes someone sends me a message saying they can tell I am using an AI voice and they wish I'd just speak for myself. I always tell them my sys admin won't let me.
12:03 I totally agree it just starts to pop! I am amazed there is no Ha filter data in there. Simply amazing! Short subs are nice and can give you a bit better sharpness and are more forgiving. In low LP areas, longer subs should give better SNR and help reduce the pebbling. Tradeoffs and I don't think one is better than the other as long as it works :)
It’s interesting to compare my tulip with yours. Since I live in Mississauga I need to use narrowband filters like the Optolong L-ultimate. I also try to keep my subs short, for me 4 minutes each. All for the same reasons, minimal loss per sub and reduced guiding requirements. I don’t think it’s possible to use broadband filters in my sky for such objects. Cuiv did a livestream where he was controlling a beautiful scope in Chile under Bortle 1 skies. My jaw dropped when I saw the broadband subs, it almost made me cry. We have paid a huge price for progress.
I agree. I was talking with a friend who was hosting an exchange student from Hong Kong a couple years ago. He said they went outside one night and she just stopped and stared up at the sky for an hour in wonder. She was crying and told him she had never seen a star before.
In nina min 56(2x) means all your pixels are above 56adu with the lowest 2 being 56 adu. So no dark clipping. Nina's histagram is not the best :) Also nina lacks any plugins to deal with owls.
As I understand it, the more light pollution, the more you need longer subs to mitigate shot noise. But I don't really know anything about dealing with light pollution other than what I've studied about it. I've lived in the backwoods of the north all my life. I've never done astrophotography in areas with any light pollution, so I have no meaningful experience in how to deal with it.
Hi! I was wondering if you could make a video about those SWIR camera, how and if we can use it for astrophotography and as well how to post processing?
I would love to create a dedicated IR setup. It would doubtless improve atmospheric influence on the images. But at this time I don't have a SWIR camera nor the optics to handle one.
Excelent video ! Just a little question, your stellarium catalogue seems to be way larger than mine. If I click above the same objet I have no descrition. Is there a way to add more catalogue to the app ? Thanks in advance
In Stellarium, go to the left and click on Sky & Viewing Options. There, click on the DSO tab. In the tab, you can select which catalogs Stellarium shows. I have it set to show all the catalogs.
@@SKYST0RY One more thing, Is there a way to save the preferences for next use ? Every time I close and re-open the app I have to do it again., Thanks in advance
To a beginner like me, the sky is like candy shop and i need try at least one of every type. That is slowly changing as i get better gear and want better results :(
If the image were being created by a single exposure, I would say yes. But raising gain would be the hardest limiter on dynamic range. Operating at unity works almost entirely around that while boosting the signal above the read noise. The offset helps every photon to count, and stacking adds the light of one sub to the next so that in the end even the darkest regions resolve. And the shorter exposures lessen the impact of the bright stars by minimizing the number of pixels who's well depth is swamped with photons. If these strategies have any meaningful negative effects on DR, I don't see it. But every step in photography (including astrophotography) has a price, a cost vs return relationship. I find the benefits of the short subs more than worth it.

I really enjoyed this. After all the money we spend on gear and all the hours we spend learning, integration time is free and the payoff is high.
Absolutely! Every professional knows it's a lot more about technique and application than gear in the end.

I've been thinking of blending exposure times on these dim targets to bring up those darkest regions, much as one does with HDR stacking.
Great video, I loved the journey, and wow, what amazing result!
WOW! Great pictures!
I wish, I would have less light pollution in my area!
I imagine light pollution is a beast. One thing I've learned is a strong preference for LRGB. You get so much more information.
Word of the day, Pebbling! Learn something new every video. Love your work. Voice is a little off, but content is great.
Astral results! Really great images.
I did not understand a lot of this. It was very pretty and illuminating.
I've started andromeda, got total integration of 15 hrs 42 mins, looking to get another 15 hours to double it. Total integration is key!
Yep! Just keep piling it up.

I have been trying to get a petition going to force NINA developers to make an anti-owl plug-in.
@@SKYST0RY ithose nina developers simply dont give a hoot
Without a SCT, quattro 15P, Fra 300 or Askar 103mm is it also better to take subs of 60sec in bortle 5 (south of Spain ) ??? great video BTW Thx

@@SKYST0RY will try to test it Thx
tutorial on how to get clear skies please
NINA has a plug-in for that.

@@saulontheroad9605 That is a problem with Stellarium. I don't know of a way. Some things save, some don't. I have never been able to figure out why.
To a beginner like me, the sky is like candy shop and i need try at least one of every type. That is slowly changing as i get better gear and want better results :(
With possibly infinite objects, it's always like a candy shop.
why do you shoot only 60s subs?
It's a somewhat arbitrary choice, but a good compromise between short subs and seeing enough structure to see what the camera is focusing on.
Won't this left biased histogram limit the resolution of your dynamic range?
If the image were being created by a single exposure, I would say yes. But raising gain would be the hardest limiter on dynamic range. Operating at unity works almost entirely around that while boosting the signal above the read noise. The offset helps every photon to count, and stacking adds the light of one sub to the next so that in the end even the darkest regions resolve.
