M16 HaRGB

[rat156]

Hi All,

After a month of no imaging and a new scope sitting around...

Finally a clear night.

After relearning how to image I managed to cobble together an M16 in HaRGB. I used 60 minutes for the Ha in 5 minute subs and 30 minutes each for the colour, again in five minute subs.

Taken with my Deep Sky Instruments RC10C. Had some guiding issues, need to polar align again after the scope change.

Cheers

Crisp detail, Just had a look at the companies website for the new scope, good looking number, and the back focus train didn't look awful either. How did itnshape up against the Meade 10 inch in your opinion.

Beautiful image mate... Good to see your 10" produce the goods for you mate!

Nice detail Stuart. It is very sharp and looks well processed. Only concern is the star saturation. Red stars showing but blue is not present.

Stuart, a great view of these pillars. What focal length did you use, and was it taken from a dark-sky site?

Very nice.. Up close and personal!

It's easier to use than the Meade RCX, no problems with dewing, collimation should be a snap as they have marked the centre of the mirrors and I now have a Tak collimation scope.



Thanks Alex.



Yeah, not happy with the star colours myself, I'm planning on adding in LRGB short exposures of the stars to it later. If we ever get clear skies again...



Fl = 1854mm, Werribee is on the outskirts of Melbourne, no dark skies here...



Thanks Trevor



Just the way we like it, no WW here!

Cheers

Great going Stuart. There aren't many M16s that have been posted on IIS that would beat that! Clear as a bell, but still soft and smooth on the eye :thumbsup:

Smooth and noise free Stuart, some excellent detail there. Stars are a bit biggish, could be due to the guiding issues, but nice to see a WW free image :thumbsup:.

Maintain the faith :thanks: :D :thumbsup:

Lovely image Stuart, As far as I can tell, we've had our one clear night this Month, think of all those good long sleeps!

You got some great detail there Stuart.

Nice image. Your RC is strutting its stuff.

Hi Paul,

I've investigated where I lost the colour in the stars. It's when I blend the colour into the luminance. Because the Ha stars are smaller than the colour ones, I get the dreaded grey rings around the stars. The fix is to run a small minimum filter through the colour layer first, unfortunately this can desaturate the stars. The best fix is to get some RGB of the stars separately, which I'll do if I get time.

If you think about it I'm asking a lot of the camera, the dynamic range between the bright stars and the nebula is very large, Ha stars just accentuate the problem.

Oh well, next clear night...

Cheers
Stuart
