Ngc 7606

This is a galaxy I've always liked the look of but never attempted until now. I think it needs a lot more data to do it proper justice so I will probably go back to it. Seeing conditions were generally pretty atrocious.

Cheers

Steve

A tiny and not often imaged galaxy Steve. Nice colour and processing.

This turned out very nice Steve!
Some lovely structure showing up and perfect colours!
Your star profiles look real good as well!

Probably more data if any thing would smooth the background but it looks pretty nice as is.

I'm working on Ngc300 at the moment, now I have broken the 4min sub wall with the OAG.
Been wanting to get this faint but larger beggar for a while.. So far 3 hours lum but will need twice this to resolve the faint star structure.

Keep these obscure galaxies and objects coming Steve...
Always great to see...

Rich

Thanks Rich. Yes it came out better than I thought given how bad the seeing was. I might try for more data in the next few days. Good luck with NGC 300.

Thanks Paul. I don't know why it's not imaged more. I would love to get it from your Clayton site rather than the light polluted cr*p sky here.

I've been doing a little tweaking of this one in an attempt to liven it up a little but I think the best thing would be more data. Some photos of this galaxy show it looking a little drab though so maybe it's supposed to look this way.

Cheers

That's a little whirlpool huh?

Great galaxy

I like the revised image more. The first had too much magenta in the outer rings, perhaps colour extinction.

Very nice and good on you for finding a new target. It gets increasingly difficult.

Greg.

Yes the magenta was the main reason I did a reprocess. There's certainly plenty of un-imaged stuff up there which would probably look good in your CDK17.

Thanks Mike. I'm surprised that this one doesn't get imaged more.

Hey Steve

I see you continue your campaign of finding the 'not often imaged' targets. Well done on this..it actually looks like a (very) far off M31.

Cheers
Martin

I agree with everybody else that this galaxy has an interesting and complex structure.

I have a question for all of you who are contributing regarding this galaxy:
Is this galaxy precisely planar, or does it have some features that extend away from its principal plane?

The presence of non-planar phenomena in spiral galaxies is actually a common occurence that seems not to have found its way into many textbooks as yet. (bends, warps, sections of a galaxy at a different p.a. to the rest of it, arms extending away from the plane, etc)

Here's the image from the Sloan Digital Sky Survey, for comparison purposes:

This object was also imaged at very high resolution, with a 24 inch RC, by Adam Block at:
http://www.caelumobservatory.com

The following is from the survey known as OSUBSGS:

[the left panel is a B-band ("blue") image and the right panel is an H band (near-infrared) exposure ]

Even in the near-infrared exposure from OSUBSGS, there is some rather peculiar looking structure seen, despite the fact that NIR images do not show most of the semi-chaotic material that we see at optical wavelengths(< 1 micron), such as heavy dust clouds and OB stars.

Thanks Martin. I'm a bit surprised this galaxy isn't better known because it's bright and quite interesting structurally. It's easily visible from the north so maybe you could have a go with the CDK17. I'm sure it would blow away my feeble effort.

I would guess that this galaxy might have tidal tails whichmight show up in a much deeper exposure

That's a very photogenic galaxy, it has a nice swirl to it
A great image with lots of detail and nice colours too.

Thanks for the comments guys. I've posted yet another version today. I managed to squeeze a bit more detail and colour out without, I hope, making it too overdone. I doubt whether I'll get any more data at this stage given that the weather seems unlikely to cooperate.

Cheers

Steve
