NGC6188 HaOiiiOiii

multiweb (Marc) · #1 28-05-2011, 11:20 PM

I did a lot of Oiii over three nights this week. 68x10min. Tuesday, Thursday and Friday so a bit over 11h.

I got very good seeing Friday from 2:00am onwards. Thursday was average and Tuesday not too good. All nights were very wet though especially Friday.

Still managed to get tight stars and not much bloating. I have a long way to go to do the other panels but this one is done and blended with the corresponding Ha.

There's a bigger version here (1934x1280) which is approx 60% - [2.75MB].

The blend turn out ok I reckon. I like the blues so I pushed them a bit. Personal preference.

Thanks for looking.

That. Is. Awesome.

WOW!

If I could add that to a favourite images list, I would.

Thanks H. Should work now to see the big view.

I must have copy pasted the link while being signed in. Weird.

Thanks David.

Thanks Allan.

It's part of a mosaic so the framing was not important. I just registered it to the Ha scaffold. That's the full frame of the CCD.

I agree with H, that is an exceptional image

I like the blues too...fav' colour, actually

Very well executed Marc.
Congrats on a real keeper.

You should be really pleased with that Marc! It's a lovely image! 680 mins of OIII is a lot of data and a big effort - and it's paid off!

Looking forward to seeing all the panels done to the same standard - it will be a killer mosaic!

Cheers, Marcus

Wonderful image Marc, thanks for the view. All the best for more.

Very nice detail Marc. 11 hrs is wuite a committment for the first panel - how many do you intend to have for the whole image?. Looking forward to seeing the finished image.

RobF (Rob) · #12 29-05-2011, 10:34 AM

Yep - we don't all have a "Sao biscuit" for a sensor....

Thanks a lot Carl.

Blue's always the hardest color to get for me so I guess we crave what we miss.

Thank you very much marcus.

Yes it was painstaking with a small aperture. But I want to make sure the final is not overwhelmed with green Ha when I use the proper palette.

I think 4 or 5 will cover the area. Then I have to do Sii which is going to take probably longer than Oiii. But Sii will be sharp. Oiii is the channel where you have to watch out for star bloating and you need good seeing and shoot close to the meridian.

With a big spread of mustard.

The full complete mosaic should be nice. Then I can go back to shooting M8

Thanks for showing me how it's done

Wish the FoV was this wide for my shot.

Can I ask about the processing? How do you go about the Ha and the OIII? Do you play with the Ha first, stretch it etc until it looks like a good image in its own right? Then do the same with the OIII separately, so it looks like a good B&W on its own? Then combine them into the different channels?
