Wow, what bortle sky was this shot from?

Lovely image, you've really done well balancing the light centre to the dark outer nebulosity.

Bortle 4, I use the astronomik cls filter which I think it’s pretty good

That's great, I've got about 16 hours of data from my D7500 and sliming that down to the better frames (13hrs) I'm struggling to get near that, would love to know more details.... scope/software/crop etc?

Nice Iris.

I have data for this target i have to reprocess , hope it will be a sgood as this,DSLR aswell.

Thanks am surprised too with the clean data, largely luck to be honest, it was a absolutely perfect seeing night when I shot it, and I dithered every two frames

it was shot with SW250 quattro, processed in Pixinsight. I followed a few YouTube tutorials as I don’t have a set work flow yet

Thanks PI here too though given it's such a long time since I used it I'm back on using youtube to assist too LOL

Mines on a 80 so probably explains the difference in IQ.

 

Great shot

Nice subtle image that hasn't been pushed too far for the data, I like it.

Very nice. I actually grabbed about 3 hrs on Iris last night for the first time - but with a little 72ED from maybe Bortle 8/7 skies (but with an Astronomik CLS-CCD too ).  Have yet to process it, but somehow I don't think it'll come out like that 🤣

[vineyard]

As I suspected. This is nominally the same object 😂 but from Bortle 8/7, 72ED. To borrow a line from Jaws, I'm going to need a bigger scope for this one!

Stay safe,

Vin

Not necessarily, the dark nebulosity does spread quite far.

Ah ok, thanks. The original image is so clean, I just had to chuckle seeing my hack at it!  Cheers & stay safe, Vin

Dang what a great picture, i can only dream of reaching this level, /runs to delete his crappy pictures before anyone sees them

Hi Vin. I got a similar result with my DSLR and 3 hours worth. I think this one needs dark skies. One for a star party I think.

Am thrilled my little photo still receiving attentions 😁.  I have plenty of noisy pictures that I hide from the world.

Good calibration frames and careful processing will go a long way.

Couldn’t agree more.  The pain of shooting with dslr is that I cant control the temperature and shoot darks at a later time.  

after 3 hrs on the lights, it’s tough to stay up another hr and half to shoot the darks.  

but it really is worth the effort.  I brew a cuppa, and watch an episode of something to keep me awake
