Antennae - QHY11

[Enrique]

My second LRGB. This time I used the eXcalibrator for color balancing.
Scope: RCX400 14"
Camera: QHY11 @-25 deg
Guiding:SXAO-L
Frames:LRGB:360:120:120:120 min. Subs: 10 min.

I hope you like it,

Enrique

Thats an exceptional image, very nice, excellent galaxy and star colour, and heaps of detail. Also clean and tight focus/guiding at that FL.What speed did you get the AO-L to guide at?. Are you useing a focal reducer?.

[Octane]

Apart from the weird star colours (particularly the blues), and a few errant coloured pixels, that is superb.

Excellent work.

You have a point there, but I like variety anyway.

A very nice image. It must feel great to image at that focal length and get nice round stars. The AO unit must be working nicely.

How do like it?

There's a couple of stars that stand out. The big blue one near the object (you'd be better off erasing it - blasphemy I know but better off).

Theres a yellow one with a red outer ring. That could be selected and median filter or gaussian blurred to get rid of the red ring. Or select it and play with selective colour or use the sponge tool set to desaturate to get rid of the red (after you zoom right in on it).

The stars look nice further out in the image.

Looks good to me. I like it better than mine.

I like the galaxy colouring in this image. Very vibrant and good saturation. Nice star shapes for that resolution too. RCX400, these are nice scopes.

[Enrique]

Thank you very much for your comments.
Regarding the guiding with SX-AOL:
I am running at 5 frames per sec. This is equivalent to 3-4 Mhz. I am trying now with 6.5 frames per second (5-6 Mhz).

Regarding the focal reducer: I am not using a focal reducer. The scope is working at F8 that is 2800 mm aprox.
Regarding the colour of the stars and the rings around them: I did not change the colours of the stars. That is how the camera sees them after I applied the correction factors calculated with eXcalibrator. The rings appear on the saturated big stars. I replaced the saturated area with the colour in the ring. Tricky process. I try to minimize the manipulation of the image.

Regards,
Enrique

Very nice Enrique. This galaxy would benifit from a bit more focal length but you have managed it very well. Looks like the QHY11 works very nicely.
Well done.

[Ephemeral]

Very good I like the colours
