NGC's 3579, 3582, 3584, 3576, 3581, 3586

Hi All,

Here's NGC 3579 in Carina.

Ha, RGB, 300, 30, 30, 30 minutes.

Usual setup, more detail tomorrow on the website. Still more Ha data to add in.

Cheers

Lovin it Stuart! Looks really nice.

OK, done a half Sidonio on this one.

I reprocessed it a bit, but the excuse I had was that I had more Ha data to go in. Also there are five other NGC objects in there, I have put in a marked up version of the photo as well.

Anyway, here it is. 6 Hours of Ha and half each for the RGB.

GSO 8" RC, G11, SBig ST-10XME, MOAG, AOL.

Much bigger (800kish) version available from here (http://tinyurl.com/ycscdfc)

Still unhappy with the grey halos around the nebula bound stars, I assume it's there for all of them, but only shows up against the nebula.

Cheers

The detail is quite amazing in the core area there Stuart.. Definitely a lot tighter FOV than the shot of this area you helped me align! :) haha.

[rat156]

We must be closer down here!

[AlexN]

hahah.. Something like that I'm sure.. :)

It has nothing to do with you having 4x the focal length and 3/4 the sensor real estate ! :D

Great job Stuart!
New one on me, and nicely presented.

[CoolhandJo]

The star colours are great. The halos are there but doesnt detract too much IMHO. Detail is great too.

Really nice detail in the nebulosity. Reminiscent of recent hubble images Stuart. Guiding is superbly tight and this helps to produce the 3D effect of the nebulosity.

Lovely image.

Very nice image Stuart. The variations in the nebula, for me makes this an outstanding image.

[Octane]

Stuart,

Wow -- had no idea there were so many sub-components in this region.

Also, your guiding is magnificent. I will save up for the AO-L unit once the STL arrives.

Cheers.

Interesting view Stuart, why that framing? Was it to get those particualr NGC's in?

Overall looks quite nice, even with the very slight grey halos :thumbsup:

Thanks Rob I found it trawling around in The Sky.



I think it looks a little yellow on reflection, might have to do a full Sidonio on it later.



The AOL was working at 15 Hz, there's a really nice bright star in the FOV of the OAG (as long as it's rotated about 90 deg from where it normally sits).



I like them too, the Ha data really brings it out.



Yes, H, I didn't know there was that much in the area, there is probably more as the reference image I was using didn't have the same FOV. The AOL will be great for you, if you're not doing much narrowband you won't need the MOAG, you can always get that later.



Three reasons for the framing Mike, firstly to get a guide star onto the chip. Secondly because I wanted some background sky in the image and of course the old photographer in me still screams "conjunction of thirds" every time I frame an image. This last reason is why my images are typically not centred in the frame.

Thanks for all the encouragement.

Now if only I can work out how to "dial in" a new set of cams for my racecar I'll have a great weekend...

Cheers

Repro is on the money Stuart. Nice work. First post reveals the highlights are being suppressed. Well done.

[AlexN]

Stuart - That area is speckled with MANY objects.. in my FOV there was 47 objects in total..

[rat156]

Hi Alex,

Yes, and it's pretty photogenic. I think I'll be spending a bit of time there.

Cheers
Stuart
