NGC6960 - Witches Broom

[fwm891]

Another attempt to get my head round the processing steps needed to go with my new ASI294MC Pro.

Definitely requires more attention in the early stages (Cosmetic correction etc) then at the end with switching between histogram transform and colour saturation to adjust the colours and densities.

Kit: AA115 EDT APO, iOptron CEM60, ASI 294MC Pro, Baader UN/IR (Luminance filter). Processing in PI.

Getting there

Very nice image Francis.

The broom is very well caught,and I like the colours.

My only negative comment would be the background.Did you take Flats for this?

Nice framing Francis. I think the darks haven’t worked as the amp glow is quite pronounced UL corner.

Thanks Mick - No flats done for this. I've taken some last night but not tried a further reprocess (yet).

Thanks Adam - I have to admit that at present getting a good dark frame correction is eluding me...

I think you need to take flats for each session, as everything in the optical train has to be exactly as is when taking the lights. 

I do this by using my laptop screen and opening notepad, really easy and quick to do at the end of each imaging session.

Does look like you need to sort out your dark frame calibration properly though, I think that's amp glow on the top right of the frame which I've read should be completely eliminated by using dark frames.

Apart from that, very encouraging. The colours look nice though calibration will make them look better and there's a good amount of detail. 

Best I have seen so far from you with the 294.
