Well who would'a thunk it ....mad Mike Sidonio imaging Centaurus A again ...oh well, I wanted something bright and I hadn't imaged her since my infamous 3 day effort over 7 years ago now and not with the current scope or camera
So here we go....
I will say that having 12" now and at F3.8 proved to deliver a bit more resolution and particularly got depth much faster than the 6" Starfire did, so that was a good thing to confirm While my last effort on Cen A was some 20hrs under perfect dark skies, this quicky is just 5.5hrs from moderately dark skies and I have processed it quite differently as I wasn't trying to bring out any galactic cirrus this time due to the smaller field. Seeing wasn't the best I have had at Wallaroo but still quite good for the Lum but unfortunately it was poor for the colour and very poor for the blue, so I had to work hard on the stars to get them to something I was relatively happy with...
Anyhooo, got my 7 year 5128 itch sorted...here she is
The inner part of the collimated jet is very clear, and I think we can see strong hints of the outer part. The dust lanes and the little "superman" badge are clear. The two bands of intense star formation either side the dust lane show lots of detail too. All that in 5.5hrs is really flying.
What happens if you register and combine this image with your StarFire version?
Great image Mike. I've noticed quite a bit of poor blue signal of late out this way. A fair amount of fog / smoke has been around, not sure if that would play any part for where you are?
Thanks for checking it out guys, hopefully it didn't stir up too many bad memories for the long term IIS'ers
Cheers John, always chuffed when something of mine catches your eye
Mike BJ, not sure but perhaps, although I already did that with Rolf mega data Olsen and I won't be able to top that effort
Greg, if the guiding is good I'm not sure the SXAO will make much difference really and that was from Terry Platt's mouth...but I too keep thinking it may be worth a try...?
Chris, re the bloated blue channel, it was like processing HaRGB, the Lum stars were much smaller than the blue ones so had to do some funky blending to disguise them...still not 100% happy...but might sit on it... for another 7 years

I have one and will be fitting it in the near future so I guess we'll find out.

Excellent, very interested to see how effective, or not, it is
