Coal Sack Dark Nebula

[Atmos]

I had planned on getting back up to Heathcote tonight to get 5 hours of Lum on this but the weather gods had other plans for me.
I was fiddling with the front lens last night and trying to remove the last of the on-axis astigmatism and I think I have. Next step is to fiddle with the backplate again and see if I can get the field a bit flatter.

Anyway, 5.4 hours RGB of which I think I need to increase the exposure time a little from 120s subs to get that bit more over read noise.

It was mostly processed in Mike's GoodLook64 but I did some end tweaks in PI.
I know the bottle right corner is terrible, thats the next thing I'm looking at when the skies clear up :)

A lovely field, Colin!

Cool deep field. :thumbsup: Got confused for a sec looking for the southern cross when you mentioned the coalsack. These are the pointers right?

That's great Col, not imaged that up close too often huh? :thumbsup:

Pretty crowded field! Hoping to get the sensor squared when the skies clear up a bit.



The brightest stars in this image are in the Tycho catalog, I tried plate solving this image using stars Mag 8 and brighter and it couldn’t do it. So there is no stars you can use as reference ;)



It is only a very small patch, need a bigger sensor than a M4/3 to do it justice hehe

Thanks Marcus. It kinda fits in as not quite wide field and not quite a tight field :lol:
