First go at narrowband

Ric · #1 10-03-2008, 05:52 PM

Hi all, here is my very first attempt at narrowband imaging with NGC5189.

My filters are Astronomik 13nm Ha, OIII and SII

This image was taken at f/5.0 but I seem to have more focussing difficulties than at f/3.3 so I may revert back for a while even though it is a smaller image.

all images were taken in Envisage at 21 seconds and 50 subs of each.

I combined through MaximDL the same as for RGB but substituted Ha for Red, OIII for Green and SII for Blue. I not sure if this is correct but it seemed to work. I still searching the web for narrowband imaging info so if anyone knows a good website please let me know.

As I mentioned I'm not sure if I have even done this right as yet so all tips, tricks and comments are gratefully recieved.

Cheers

The hubble colours are very striking, looks good

Try the Hubble palette Ric - R:SII,G:Ha,B:OIII (aka SHO).

Thanks Paul for your comments, it does jump out at.

Thanks Jase, I've noted the combination and I'll reprocess in that sequence.

Cheers

great shot ric. ive taken this object not long ago . its good to see it in narrowband. The image is abit too dark for my LCD monitor i can imagine it will be even more darker with a CRT monitor.

I've adjusted the brightness abit using levels hope you don't mind.

You're off to a good start Ric.

Nice one Ric, I look forward to seeing some narrowband delights during full moon!

Many thanks Eric, Andrew & Mike.

Eric, thanks for the adjustment I don't have any worries about having images that's how I learn what's best and what to aim for.

Hopefully I'll post another tonight in the correct colour sequence and a bit brighter.

Cheers

Cheers Barb & Dave, it's been an area of imaging that I have been wanting to explore for a while.

Yet another learning curve to add to the list
