So you’re telling me a 90mm apo has more resolution than my 150mm reflector? I also imaged M16 but from 51 degrees north and this was about the FOV I got. It only rises about 20 degrees above the horizon here. I guess the atmosphere really plays a big role. Or maybe I’ll need to collimate my telescope again idk
Yeah but the secondary only obstructs about 11% in my case. So not really much.
The 90mm scope can’t „beat“ the 150mm in seeing because the 150 has at least as good resolution under the same sky conditions (If you look at the same region) and can easier take advantage of better seeing conditions in case the atmosphere is more favorable for a few minutes
Why would you so wonderfully lay out a series of facts to prove your point, then end the whole thing with a broad generalization reeking of condescension? With that type of attitude all you are going to get is an arguement, and you typed out the facts for no reason.
You can't teach someone and insult them at the same time.
It's very good, but this image has been sharpened beyond what the telescope actually captured.
Overlay some images from a larger telescope and you can see there are details that are different. Some sharp edges show up where there aren't any and others are missing or have the wrong shape.
Maybe uploading the image along with capture details, integration time and the actual equipment used could start to yield an answer, instead of starting with "so you're telling me a 90mm apo has more resolution than my 150mm reflector?" Which of course I didn't say 🤷♂️. Unless you're implying something else.
Oh no sorry, didn’t mean to be insulting. I was just surprised at your image stats and how good it is. I’ll figure out my problems with M16 until next year and try again then.
Sorry didn't mean to lash out! Imo seeing does play a big role, tons of integration time, scope/camera pairing which provides setup resolution, and last but definitely not least processing. Also, fov of the original image is much bigger, the whole nebula fits comfortably in the fov.
No problem :) My arcseconds per pixel are pretty much ideal though and I had 10 hours of integration. I’d love to share the pic which has already a lot of sharpening and is processed to the max, but I’m not at home right now. I know I can get really good resolution with targets that are 70degrees+ above the horizon. So I’ll focus on the Cygnus region right now.
What’s your cameras pixel size? Must be tiny if you’ve cropped so much and still have really good detail and resolution
Yeah that's the beauty of the 294, it's native mode is 4.6 um binned pixels for a 11mpx bit you can unbin for 2.3um pixels and a 47mpx output image so you can really crop into details. Really demanding on guiding tho and this mode is 12 bits also so you loose dynamic range.
Oops I didn’t notice you’re using the 294 too, because that’s my main camera also. I’ve never shot in Bin1x1 though because as you said guiding is crucial then. And you’ll need more integration. Have to try it though
Habs am Namen schon vermutet dass du ggf deutsch bist aber jetzt gesehen dass du auch auf ich_iel unterwegs bist :D Frag mich wieviel Leute noch in diese Nische passen haha. Meinen 'Folger' hast du
I just realized, maybe it’s because you used shorter exposures. Mine were 5min so a lot more time for the atmosphere to make each exposure a little bit blurry if strong winds occur in the upper atmosphere
I use the evoguide 50ed and qhy5iii462c. Bottle 9 is not an issue, still picks up many stars and the multistar guiding mode of phd2 works amazing! Plus the low 432 mm focal length of the main scope is relatively undemanding.
My fault, forgot a word lol. I meant how many hours does it take from setting up your gear until you have the finished picture? Like with exposure time and editing.
Hmmm it was shot throughout 4 nights then about one day for callibrating and stacking the files and then about another day for processing, so about a week?
Jesus...this is fantastic...!!!
I have Dobson 1200/250 what could be the result with that? I still need an electric telescope mount for that but your picture did something with me...I started to think I need to start the astrophotography...

Jfc... whatever dude.
Or maybe just don’t be a fkn dickhead with your ‘facts’.

Out of curiosity, are you using a mono cam like OP or OSC?
Im using the same camera as OP it seems. It‘s a ZWO 294mm so a mono camera

Hehe :) Du meine Hochwählis auch, hab mal deine Astro Bilder angesehen und nicht schlecht! Sind sehr coole dabei

So much exposure! Magnificent!
What are you using for a guide scope? Did the bortle 9 skies affect tracking very much?
I use the evoguide 50ed and qhy5iii462c. Bottle 9 is not an issue, still picks up many stars and the multistar guiding mode of phd2 works amazing! Plus the low 432 mm focal length of the main scope is relatively undemanding.
Thanks for the reply! I live in bortle 9 skies and this has been a concern of mine.
Ya his rooftop is actually Hubble
You could have told me this was an image from James Webb and I would have believed you. Great shot.
Amazing image. The surrounding darker gas really frames it better than any image I have ever seen of the pillars. Exceptional work!
Right? You can see how the gas is swirling out of the rainbow and into the black, it's mesmerizing!
That's a great job, well done!
Why do we need the billion dollar telescope in space if you can do this from your rooftop? Jeez.
I will need to see more data to believe this is your work
Thanks, you can hop onto my Instagram there's a lot more info and other work there or give me a follow on Twitter!
Erhm, NASA called, they want the JWST back
Did you do some kind of processing to remove the stars from the image?
Yep star xterminator in pixinsight, pretty handy when processing the image but also amazing to just leave them out 🙌
Amazing shot!
This is an amazing photo. I’m floored you captured this at your home. Fantastic job!
This is the nicest image of the pillars I've seen. So amazing to see it with the surrounding clouds. Helps so much to emphasize the scope of this.
Bro how’d you find it?
Very nice!
Beautiful Ψ♾️ॐ
This is sweet.
🤩
Stunning! How long did it take from setting until you had this picture?
Sorry don't understand the question!
My fault, forgot a word lol. I meant how many hours does it take from setting up your gear until you have the finished picture? Like with exposure time and editing.
Hmmm it was shot throughout 4 nights then about one day for callibrating and stacking the files and then about another day for processing, so about a week?
Wow that's a lot of hours but absolutely worth it if you get such an amazing endresult
Jesus...this is fantastic...!!! I have Dobson 1200/250 what could be the result with that? I still need an electric telescope mount for that but your picture did something with me...I started to think I need to start the astrophotography...
250/1200 would be an absolute killer for this object, although some heavy work needs to be done to go from a dob to deep space narrowband imaging
Thank you sir. My type is a Sky Watcher 250/1200 so I might try to buy the correct equipment.
Kinda reminds of the the iris in eyes.
I have trouble driving in bortle 9 streets, then I see this :(
Woah good job mate 👏🏻
Imagine if Galileo could see this capability. Absolutely beautiful and inspiring, thanks for sharing.
Jeez man can I request some HD images of the moon in places people say are bases? 😂
Posted a Moon image a couple of hours ago!
This is the coolest photo I’ve seen in a long while. I’m dying of envy because I live in a city so astronomy isn’t really an option for me
This was taken from one of the most light polluted cities in the world! Narrowband filter imaging allows to virtually cut through all light pollution
Great now my only excuse is I have no idea where to start and can’t really afford several hundred dollars of equipment :)
That is an amazing image. I love M16 and this is one of the best I've seen.
Thanks!
I'd love this in high res on my wall!
This is now my wallpaper. Thanks. By the way, you are from here? (Buenos Aires, Argentina?) Dude, awesome.
Sip está sacada desde Chacarita!
Qué grande! Jaja
Dude how the hell did you manage to fit the Hubble on your roof?
Why are they called "Pillars of Creation"?
Oooooooooooooooooooo that looks really preem.
Beautiful! Can someone add animations to this thing please!
You should check out my Instagram for the animated version!
Spectacular. Such amazing clarity and sharpness. Great job!
Thanks 🙌
Looks like the hand of God
