A few from Sunday Night

[Daniel]

As Mentioned Im Marks post, Sunday night wasn't as great as at first thought so some nasty gradients to get around.

I also took images of the Jellyfish and M33 that night but im still processing them, on first looks, Im not sure the Jellyfish image is going to come out too well.

Anyway, these didn't come out so bad considering the sky glow.

I shall post details later suffice to say there all 180s exposures at ISO 160

Gosh Daniel, a few a night!! 180 secs ......................sigh

Superb.... especially the horshead.. Guess you must have been up late if you got m51...... brilliant. John

You tackled the flaming star the same night as me!  Yours is a much cleaner image, but then it should be, because at F2 you are collecting 10x as many photons as me.

The horsehead and flame image is fantastic.

I'd like to see both at full scale.

You must have done an expert job at removing gradients. 

I think M51 really needs more focal length to do it justice.

[Daniel]

Thanks guy's, here's some "warts 'n' all" 100% crop images, as you'll see my Flaming star is MUCH noisier than Marks.

The M51 was the last image I did that night and it was almost at zenith at about 5:00 am!!
