M33 in narrowband

[RickS]

This is a Ha/Oiii bi-colour of the great M33 with RGB stars for flavour. Data captured at SRO in California.

I'm not completely happy with this yet but I need to stop processing it and take a break before I have a run at it again :) I think it's reasonably presentable now and certainly different enough to the usual M33 image to be interesting.

Scope: Ceravolo C300 @ f/4.9 = 1470mm FL
Mount: AP1100
Camera: FLI PL16803
Focuser: Atlas
Filters: Astrodon
Guiding: Lodestar II / Tak guide scope
Image scale: 1.26 arcsec/pixel (drizzled to higher res)
Exposures: 30x1800s Ha, 8x1800s Oiii, some RGB
Processing: PixInsight 1.8

bicolour narrowband galaxies now??
interested to know how much Oiii you manage to get on a galaxy like this?
as the swedes would say varför inte? Why not!?

cheers

Hi Rick,

I think it's an awesome composition - not sure what can be done to improve it.

The galaxy appears to be so alive with numerous star forming regions!

[RickS]

Thanks for the comments, Russ. You have to try new things. Sometimes they even work :D

We only got 4 hours of Oiii which really wasn't enough for good SNR but there was a surprising amount of it. As you can see, there are only a few areas that are strong in Oiii but not Ha. I have an hour of Sii as well but it is pretty weak and a lot more data would be needed before I could do a Hubble version.

Cheers,
Rick.

Thanks, Suavi! I have a mental picture of what it should look like and it's not quite there yet.

It certainly does show M33 in a new light... no pun intended :) There's a lot of structure the RGB images only hint at.

Cheers,
Rick.

Awesome, delightful, and inspiring :thumbsup:

[RickS]

Thanks, M&T. It would be interesting to see if something similar could be done with a southern galaxy, say NGC 300?

Cheers,
Rick.

Great work Rick.

It really highlights the massive amounts of gas in these galaxies.

Greg.

[multiweb]

Love it. That looks awesome. :thumbsup:

[RickS]

Thanks, Greg & Marc!

Crikey that's different. Be very interested to see where this goes, but it sure is a great idea and already a very nice image.

[topheart]

Fascinating!
Well done!

Cheers,
Tim

Great work Rick, nice to see such a different take on a commonly-imaged subject!

[Fabiomax]

Very interesting approach and detailde informations about different envirinmental .

[RickS]

Thanks Ray, Tim, Lee & Fabiomax!

Interesting approach Rick. Looks "angry" - like a single match would set it all off :)

Great data. Will be interested if you do try other approaches.

This NB galaxy imaging thing is going to catch in I think. Great the way it brings out all of those star forming areas and the bicolour works a treat.

Nicely done :thumbsup:

Awesome Rick! Thinking outside the box, fantastic! :thumbsup:

[Paul Haese]

Like I said on FB, it's different. I think the colouring works well, though it still looks odd for a galaxy Rick. An interesting examination all the same.

[RickS]

Thanks, Rob. I've done a few "angry" images now. Must be my thing :)



Thanks, David. I don't think there are a lot of galaxies that are bright enough in NB to do this but it would be interesting to find out!



Ta, Rod.



Thanks, Paul. It is definitely odd!

[Somnium]

wow Rick, really interesting take, well done

[RickS]

Thanks, Aidan.
