NGC6992 - HST palette

[Paramount]

Hi
I managed to get some SII data last night to go with the other two channels from a week or so ago, there was a large patch of cloud that interupted the session for half an hour or so but luckily no more for the rest of the evening. This was taken with a FSQ106ED at f5, ML8300 and 5nm Ha, OIII and SII filters on a Paramount ME, auto guiding was taken care of by a lodestar and OAG using dithering.
Exposures are 6x30 minutes Ha, 8x30 minutes OIII and 9x30 minutes SII. These were then mapped using the wavelength ordered palette of SII:Ha:OIII = R:G:B

Thanks for looking

That's a top picture.
Still a little bit if noise but the full size looks great.
You also have such perfect sharp stars across the whole frame.
Looks like you have your system very well sorted.

Hi
Thanks for the comments, as I agree that there is still a bit of noise and I will be trying to get a bit more data especially Ha as I've only got 3 hours, and ideally I would like 6 hours for each channel where the signal is fairly equal as in this subject, and I only had to tweak the OIII slightly when equalising the histograms

Hi Gordon,
I suppose if you've got good weather it may be worth spending the extra time
but really what you have is dazzling enough.

What was the focal length for that shot?

A great photo Gordon.

The detail is amazing.

Hi
Focal length was 530mm which I think is the native focal length of the FSQ 106ED at f5 and the camera was a ML8300, this produces the perfect FOV for this subject
