Into the Core of M33

[Rodd]

About 32 hours of data with TOA 130 and .7x reducer.  I concentrated on teh core.  The first image is a crop of the core.  The second image is the whole galaxy to the same scale.  I think the crop is easier to look at, but I wanted to include the whole image.

[Rodd]

I have been tinkering with the dust lanes.  They are more clearly seen in this version--but it might be at the expense of depth.  please let me know which you prefer--the initial crop, or this one.  I can';t quite put my finger on it and I am torn.

Great image, Rodd. I like crop 1 better, but maybe a dose of SCNR green on the second version would give that an edge.

great image. I like the way the core fills the entire frame.

Thanks Tom. I was surprised it held together at this scale

Well, I removed a bit of red from #1 because the dust should not be pink. That happens when the Ha is inserted too broadly. I did not think of green. You make a good point.

Great images Rodd! I agree with Wim that a bit of SCNRgreen could help the second one to be the winner. Amazing how much more detail can be seen in the core of M33 compared to M31. I assume it means that the center of M31 is much hotter.

Thanks Goran--I'll see about scnr green--I have come to like #1.  If I remove green, the dust will be red again (pink);.  I'll give it a try and see.  Regarding M31--not sure why.  M33 is even a bit farther away than M31 and you can see more.  I expect it might have something to do with the angle we see it at.  M33 is almost face on while M31 is at an angle.  But who knows.

Well--not quite SCNR green as I do not have access to PI at present, but close enough for Jazz as they say.

Better.

I think that we see more detail in the core of M 33 as compared to M 31, simply because M 33 is a different type of galaxy. M 31 and the Milky Way have a massive black hole at the centre, with a bulge of (old) stars. M 33 lacks both a central black hole and a bulge, it's a pure disc galaxy. It also has a much higher rate of star formation than M 31.

That is true--thats quite a difference in morphology.  The angle of incident probably does play a role too, though, I would think.  Its quite different

It would be interesting to see a galaxy like M33 edge on. Andromeda probably looks like ngc 891 when viewed edge on.

I think the dust lane in M31 is bent a bit--distorted from interacting with a companion.  It would be interesting to see M33.  Its hard to imagine a single dust lane
