UFO? Nah...just M104
M104 using a much tighter crop with some reprocessing using same data I posted last year.

Very Nice Peter, This is probably the most detailed image of Sombrero I have ever seen. Although I make a noise about repro's, all is forgiven for this work of art.

Thanks Steve, Craig, Troy.
It was fun to re-work the data at such a large image scale.
I must admit to having used some artistic license and applied some localized/layered sharpening....but don't think the result looks over-cooked.

Thanks Fred (& Petra & seeker). Narrow field rules OK! ?
Just some thoughts on the image data.
I recall there was a conveniently placed guide star for the AOL to work on....at around 10Hz.
plus the seeing (due a large blocking High and consistent fog in the mornings) was..well...as good as it gets in my neck of the woods.
But I didn't use a focal extender.....hummmm....

Impressive to see what the professionals, or rather ultra serious semi-professionals can do!

Well Peter, that is pretty good data there.
I like the way you've pushed the processing as well, some of the colours are off a bit, but really that's not what you're looking at.
I think they cheated with the Hubble image and used IR (or a blend) for the luminance anyway, that's the only way you could get that transparent effect isn't it?
I'm trying my own M104 tonight, the seeing isn't that flash, but it's nicely placed and like you mentioned there's a nice guide star (or three). My only problem is with that I've had to rotate the camera about 90deg, so the scope is now out of balance slightly. I'm getting about 7-8Hz corrections still, so it'll be interesting to compare the results to find out what all that extra money gets you. You'll be able to use the comparison on your website, $6k scope vs >$50k? scope and mount.
Cheers
Stuart

I think I'm gunna have to be happy with 97%, unless Uncle Kev starts a rather larger stimulus package...
Still happily acquiring luminance.
I assume you binned the RGB subs, but did you still guide at 10Hz?
I won't be able to do that through the filters, but I'm wondering if it's necessary anyway as I'll bin them anyway, thought?
Cheers
Bruce

That's the best I've seen. The processing and the color change between the blues and orange/yellow is outstanding. I've looked at the HST version a while ago but I have to admit this is much better processed. The way you brought up the colours in the details is just amazing. It's simply the right balance of softness and sharpness just in the right places. Outstanding.
