[Repro added] M83 - First light with new QHY9M CCD camera

[multiweb (Marc)]

What a great shot. Superb colors and details!

Lucas, thanks for sharing this real humm-dinger of an image! Welcome to the world of mono imaging. You're wise starting off with a straight RGB composite to get your feet wet. Good work on the synth lum too! Out of interest what give you the best result when combining the data, sum, average, median? I typically use sum to good effect. I'm really looking forward to see how you progress this this quality set up - some narrow band perhaps?

Lucas,

Thanks Nathan and Allan. I am using an APM 130mm F6 Triplet APO refractor on an NEQ6 Pro. For guiding I am using a TSOAG9 off axis guider (which I had left over from my DSLR days) with an orion starshoot camera. I control the QHY9 with Nebulosity 3 which can also talk to PHD guiding software so I can dither my subs also. Each Filter was 12 x 5min subs.

Hi Lucas,
Thanks for the info.
That APM 130mm is a beauty - a high end scope.

I like your new version.
The same always happens to me - reprocessing my data in some way.

As for Luminance - I understand the problem from a light polluted site.
I think I will try my 2" Astronomik CLS-CCD filter the next time.
In fact I could probably leave it in place & do all LRGB with it on.
It will of course mean longer sub-frames but with a cooled camera
the noise is not such a problem.

Best of luck - you've made a fine start - a wonderful introduction into
the higher quality of CCD imaging.

cheers
Allan

Thanks Jase. Your comments and encouragement are much appreciated. When combining the data I use Nebulosity which uses an adaptive stacking function which gives you best of sum and average. My understanding is that it will use sum unless saturation occurs at 65535 then it will use average. As for the future, I am looking to both LRGB and narrow band. I already purchased a 7nm Baader Ha filter with my LRGB set so I will need to invest in the OIII and SII filters for starters. Would probably like to get the dedicated 0.75X Riccardi reducer for the scope. The F4.5 and wider field would be very nice options.

No worries Allan. That's what is great about posting images here on IIS. People are always willing to give you some constructive advice for improving your images. Thank you and best of luck with your imaging also.

Great first photo from your new camara Lucas.

I really like the "bluer" version.

Ross.
