Horesehead reprocessed

Posted By Greg Bradley
I've been reading Ron Wodaski's/Russ Croman's zone book so I reprocessed my recent Horsehead.

I used Gradient Exterminator and also created a luminance channel from the colour data to boost detail.

I also worked hard on the star colour and corrected a small amount of star trailing.

The original is a few posts back on this forum.

Going through an older image from last year using Gradient Exterminator and Photoshop processing techniques salvaged an otherwise rejected image.

Can someone advise me which model Canon 200mm lens is the common one used for astro work?

Thanks,

Eta Carina Ha widefield

Posted By Greg Bradley
After spending nearly 4 hours correcting a bad polar alignment and sorting out my autoguiding (it is so easy to get lost in the technology of this hobby) I finally managed to get a couple of quick shots of Eta Carina.

I was very surprised they turned out so well. Of course clouds moved in after being clear the whole time i was fiddling with my gear! This is 2 x 5 mins 30 secs (1 minute of one exposure had cloud over it!), Baader 7nm Ha filter and FSQ/STL11000CM 2x2 binning. NJP mount.

Eta Carina is brighter in Ha than I thought.

This is really a sneak peak as I intend to capture perhaps 4 or more hours of Ha and then lots of colour from a dark site.

I just reprocessed this one to get the background stars back and to mix it all better using the techniques at the end of the Zone System book by Ron Wodaski and Russell Croman. A very good book. I like this one better.

Posted By Greg Bradley
I've added an hour of O111 data to both of these recent images and I like the effect:
