M17 ngc6618 Omega Nebula

[TrevorW]

24 Frames 16 minutes ISO800 unguided through the 120 f/5 taken tonight around 8:30-9:15pm seeing not great because of moon focus slightly off

Stacked DSS processed in PS for levels and curves etc

Trevor - how long were the individual exposures in the image (1.5mins?) There seems to be quite a bit of noise - did you subtract darks?

Cheers,

Peter.

[TrevorW]

40 seconds per frame

yes but my darks and lights were not as long exposures as the image frames

probably could do more work with PS will attempt again

I'm not sure what is causing the diagonal noise but for only 16 minutes worth of data.

You have done a good job with it. You could probably bring it out more in PS but that is up to you.

Well done. Keep at it.

Errr...
It is not Omega Centauri, mate

Otherwise, looks good... you must be living in dark place.. I envy you

Trevor said it's M17 ngc6618 Omega Nebula , not Omega Centauri.

A lot less noise in the second image - is it from the same exposures?

Omega Centauri is written on the second image.

Typo on second image have replaced this is the same exposure different processing will work on this raw data more to see if i can improve

Thanks

Ah I see.

Grasshopper. This is not good. The secrets of the universe will not reveal themselves unless you take much longer exposures, polar align and guide well.

Also, use the focus knob......

Thank you Master for you words of wisdom !!!

Hi Trevor, Shows some promise but you need to fire off a lot more images and longer images. Get some guiding going and your images will improve dramatically. Also with the moon up you will also improve things somewhat by taking some flat frames also.
