M104 the Sombrero Galaxy Now in colour

gregbradley · #1 10-04-2018, 07:10 PM

A favourite. Some excellent seeing and the small pixel size of the Microline 16 gave some good detail.

I have the full data but for now here is the luminance image. Make sure you see the large image.

Great detail in the dust lane, Greg!

+1 Great detail there Greg. I'm too lazy to look it up and since you likely already know, what's your imaging scale in terms of "/px ?

Peter Ward · #4 10-04-2018, 07:42 PM

A great result.

That's a very nice sombrero Greg!

Cheers

.42 arc seconds per pixel so it really needs good seeing to work.

Thanks Peter. Your stellar M104 was uppermost in my mind when when I wasntaking this shot.

Great work Greg. It's very easy to overblow the centre in an attempt to show the outer regions but you've processed it nicely. It also looks very visual. I remember looking at this with a 25" scope on a night of good seeing. It looked pretty much like your image although not as much detail in the dust lane

Nice image Greg, I saw it in Allan's 32" Dob and it looked just like your photo.

Sounds great. I'll have to get back into some visual observing. Its very rewarding.

Thank you. That must have been quite a treat.

Greg.

Nice pic Greg,
it's not easy to get detail in that dust lane on
such a tiny dim target.
I look forward to the colour version.

cheers

Nice image there Greg

You have also scored quite a few of it's globular Clusters.

Ryderscope (Rodney) · #12 11-04-2018, 01:10 AM

Lovely. Good detail and nice processing.

topheart · #13 11-04-2018, 08:40 AM

Nice one Greg!!
Cheers,
Tim

Atmos (Colin) · #14 11-04-2018, 08:57 AM

Such a lovely image Greg. Many images I’ve seen of this usually show the dust lanes as a dust bar so Harding that extra contrast is lovely to see.

Placidus (Mike and Trish) · #15 11-04-2018, 09:00 AM

That's Premier Cru, Greg. The sharpness is remarkable.

Stevec35 (Steve) · #16 11-04-2018, 10:18 AM

Looking good Greg. The colour should be spectacular.

Steve

Terrific image - I'd love to see the full colour version when it arrives!

Some nice details there Greg

I am going to the US in May to the Texas Star Party with a few astro mates and as part of our trip we have booked a whole night observing on the Hooker 100" scope at Mt Wilson (for just four of us!!)...and even given its slightly southern declination, M104 will be nicely placed, so I can't wait to see what it looks like through a 2.5m telescope under (hopefully) some good seeing that Mt Wilson can get

Some great resolution Greg, the colour will be awesome.

Thanks Allan. I am hoping the colour brings out a bit more.

Yes I noticed that. There are quite a few.

Cheers Tim. It must be coming up to the dry season in Cairns?

It was a great night of seeing, several nights really. It makes all the difference at that image scale.

Thanks Mike. Hopefully the Microline 16 and the CDK 17 perform this well most of the time.

Wow, what an awesome trip. Definitely write up a post about it. Sounds like a dream trip.
