A colourful Swan

[RickS]

It hasn't been a good year for clear weather on new moon weekends, so all I have is more narrowband from home :mad2:

Here's an image of M 17 which started as Hubble Palette and had a bit of an accident. I was trying to do something just a little different...

Scope: Ceravolo C300 @ f/9 = 2760mm FL, Atlas focuser
Mount: AP900
Camera: U16M
Filters: Astrodon E series Gen 2 LRGB
Guiding: Lodestar / MMOAG
Image scale: 0.67 arcsec/pixel
Exposures: 8x1200s+11x1800s Ha, 7x1200s+18x1800s O3, 7x1200s+31x1800s S2, 7x300s R, 7x300s G, 7x300s B
(8.15 hrs Ha, 11.3 hrs O3, 17.83 hrs S2 - total 39.08 hrs)

High res is on Astrobin: http://www.astrobin.com/115053/

Hope you like it. If you don't... tell me why. I appreciate the great feedback I've had from folks on IIS :thumbsup:

Cheers,
Rick.

Hmmm? Ricki :rolleyes:...I dooon't think it is quiiiite deep enough :question:...I'm sure there are a few iti bitti spaces in there that could be filled in with some more nebulosity :shrug:.......:P

Ok, seriously :D I like it, heaps of neb everywhere, specially that light blue outer stuff and yes the somewhat pastel colours are different but in a good way I recon :thumbsup:

In the end you can go round in circles with this narrowband stuff if you try and meet everyones expectations :)

Very nice close up Rick! I like the light blues :thumbsup:

I know what you mean with the weather. It just so happens that I started my M17 project last first quarter Moon with intentions of collecting the rest of the data this new Moon, however forecasts are not very favorable for this weekend. :sadeyes:

Pretty good Rick! I think you did a better job than I did.

Cheers

Thanks, Mike! Deciding on narrowband colour is a bit like my wife picking which shoes to wear... OK, slight exaggeration. There are only 16 million colours in an 8-bit image, so the shoes are much harder ;)



Ta, Rod. Sorry about your weekend. Hope the weather improves!



Thanks, Steve. I'll look forward to what you can do with your a repro. Are you going to try for more Ha?

That's a different take to a common object. I also like the colour palette.

Amazing detail and staggering exposure times. :)

What's not to love?
Hopefully one day I'll manage exp time like that

That's a really good pic Rick. I think you've handled the dynamic range quite well. :thumbsup: Straight Ha would have looked flat but the fact you've used tri-color makes the view really interesting.

[RickS]

Thanks, H! It's not too hard to rack up narrowband hours now that I have ACP minding the scope for me. The main limitation is the weather.



Thanks, Peter. There's always something that could be improved ;) The stars for a start!



Thanks very much, Marc!

The weather. Argh!

Last night, I went to collect some more data on Rho Ophiuchus. I did my first plate solve, finished the focus run, and, the clouds came to join the party. Have stayed ever since. :(

Really pleasing image Rick. I love the colour pallete also.

[RickS]

I blame batema and his new A-P mount :rolleyes:



Thanks very much, Rex!
