Carina OB1: Part of Eta Carinae Nebula

[nandopg]

Hello,
This image shows part of the enormous nebula known as Eta Carinae, in Carina constellation. This area of dust, gas, dark nebulae, globular clusters, globules, etc.., designated as Carina OB1, has been consistently creating stars, what has been confirmed by spectral analysis.

Image Details:
Telescope: Skywatcher Quattro CF 10" f/4
GPU Aplanatic Coma Corrector: gave a field curvature of 16%
Ha: 4x600sec
L: 10x180sec
RGB: 5x180sec each channel

Image in full resolution here

Comments are always welcome.

Really good detail picked up in Ha, it shows the Fine structure of the nebula well. Great work

Some dark rings around the stars but otherwise that is a good looking image Fernando, nice job Is this a new scope for you?

Wow, that is an excellent image Fernando .

Looks like you have the SW equipment working really well. seems like that 4 element CC works very well

Terrific shot! Really cool details. The fov is just superb.

Hi Aidan,
Thank you !! I was amazed with the performance of this Newt.

Thanks for the remark Mike. Yes, it is a new scope. I need a set-up that allow me to make short subs without compromises the image. This scope came in handy, it is an Atlas Rocket, despite to be chinese.

Hi Ray thanks so much, man !!
I've watched so many videos and tuts about collimation of fast newtonians that I think I found a way to get my scope collimated, overcoming each little problem I identified in these videos. I am preparing a little video or two describing this method.
The other thing that makes a difference is the use of the 4 elements CC.

To have an idea about the overall performance of the scope, here you can see the test of the scope collimated with the method I derived and using the 4 elements CC, shown in CCDInspector.

Thanks again Ray for all your comments,

Fernando

Hi Mark,
Thank you so much for the kind comment, I appreciated.

I have compared the features present in this region with the annotated mosaic created through the Blanco Telescope (4 meters) and all the features are present in this image created by a 10" (0.25m) telescope. I was amazed !!

Best Regards,
Fernando
