It works

Looking very nice too.

thanks Dave

[ultranova]

works it does, quite impressive if that wasn't a taken from a dark site,

These wide field shots really suffer from gradients and the like

especially RGB imaging,

Nice image Chris, would be interesting to see a comparison from a dark site

Well done

Paul 

[Mr niall]

I don’t think you could ask for a better framing. Absolute cracker.

thanks Paul will do a comparison if i manage to get to a dark site i am trying to get a trip planned 

[toxic]

thanks Niall

Hi @toxic

This image looks really nice

As an advanced user of the Star Adventurer, I can tell you that you can easily get 7-8 minute subs with the 50mm lenses

I managed to get 8 minute sub with 75mm lenses unguided, than get guiding and thats a whole new story

Clear skies

With Ha you dont need thoose dark skies

Not necessarily - you just need more exposure to get the same result compared to a dark site! You will only need longer exposures if the background sky doesn't swamp read noise (eg using narrowband).

It's still a very nice shot - huge field of view!

I agree

As i said with Ha you can image from the middle of NY

thanks Graeme and serbia

no NB or LP filter its an unmodified EOS 200D with the kit lens and it gets swamped after 5 minutes at home so need a dark site for longer unless i drop the iso

[toxic]

i do do NB imaging with the 200pds and the atik 383l but just trying out my new toy and i am very pleased with it

You might find that you can drop the ISO value if you're in the ISO invariant range for the camera - very possible that a lower value will give you the same result once stacked, stretched, etc.

I don't know where that sits for the 200d (it might be 1600?) but as an example on my old 350d, I get good results even at ISO400 - it's no better (and decreased dynamic range) at 800/1600, unless I'm after moving targets.

Incredibly, I think you have managed to capture Mirach's Ghost, 'the galaxy in the middle':

thanks Neil - a happy accident
