Title: Iris Nebula from Lydd
Post by: MarkS on Jul 18, 2010, 11:13:05
Drove down to my favourite haunt near Lydd last night - fantastic sky - got back home in the early hours.  Decided to image something tough but different.

So here is the Iris Nebula (processed using Iris!)
Modified Canon 350D on Tak Epsilon 180ED ( 500mm F2.8 ) with IR/UV filter only.
21 x 5min exposures at ISO 800

There's hardly any background gradient - that gives an indication of last night's sky quality.

Bigger version (though scaled by 2/3) here:

Very nice Mark, I think it needs a little more exposure to get the dark nebula to stand out from the background but thats superb for a quick night imaging session.

Did you notice all the meteors last night, I counted over 39 between 12:20 and 1:30am.

Yep - loads of Meteors - just like at Rother Valley last weekend. 

I hope to add some more exposures to the Iris sometime.

I think that is great Mark. The Canon certainly gives good results

Very nice Mark,  the dust lane colour is starting to come through nicely.  It's pretty good as it is but adding some more subs would meke it a wonderful image.

Subtle re-process here:

The core is less burnt out, stars are tighter and I've removed most of the background gradient.

It needs a few hours more data to really do it justice but I'm really pleased with this.
