Coal Sack Dark Nebula

[Atmos (Colin)]

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.

High Res version

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. 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?

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
