A now, less-noisy coil...

Peter Ward · #1 06-07-2013, 11:27 AM

I guess it's helix season...

Probably too early to publish this yet, as I need about 8x more data to tame the noise... and bring up the subtle outer arcs hinted at in this image...

...but must admit I'm pleased with how the data is progressing.

This is just 1 hour of Ha, and half that in OIII. Hope the weather holds

The link is here

Looks like it will be very nice, Peter. A great start considering how little exposure time you have.

Cheers,
Rick.

That's going to be quite nice if you can add the extra data..

Larryp (Laurie) · #4 06-07-2013, 12:01 PM

Looking good, Peter. I look forward to seeing it with more data

Thanks guys.. yep the Helix is a multi-hour affair for sure.

That said, I'm amazed that the spoke structures are visible even at this early stage.

Paul Haese · #6 06-07-2013, 12:46 PM

Yes that is quite interesting that the spokes are showing through so early. I suspect the size of the aperture is making that happen quickly. I found that 1.2 hours with the TSA was necessary before any part of the spokes really showed up. Lots more integration and you will have a winner.

The start of a great looking photo Peter.

Looking forward to the finished version.

Ross.

Yes, a great start; lots of detail already showing through.

Ta... but still plain yogurt at present.

(Spaceballs fans will understand the plain yogurt reference

Me too... got a couple more hours in last night..but won't bore everyone with progressive results.

Ta, I'm hoping it will end up with the same res, less noise, more data.

As for being a winner, there have been some heroic efforts here (I rather like Martins sublime rendition) hence I doubt I'll get the time to even be on par.

May the Schwartz be with you!! .... And deliver you more clear nights to finish this off. In between the noise, I can see the beginnings of a nice image!

Cheers, Marcis

Lonestar! I see that (soon ) your Ritchey-Schwartz will be as big as mine.

I wonder how well you will handle it!

Phil Hart · #12 08-07-2013, 09:15 PM

The colours are looking great.. reminds me of a transparency slide I had of the Helix from AAT or some other big scope many years ago. 'Feels' different to most other digital versions I've seen..

Thanks for the input Phil.... I think I'm headed in the right direction with this one

My run of clear nights look to have ended, hence "only" six hours of Ha and two of OIII are in the bag to date.

Looks like it will need about triple that to bring out extended halo well. As for the "feel" yes, it's intentional.

The extended halo is incredibly faint and I'll be trying to preserve that brightness relationship with the core in the completed image.

Peter,

It looks good already so I'm looking forward to what should be an impressive image when you get more data!

Cheers,
Mario

Thanks Mario. Given the weather has brought a halt to proceedings, I've since uploaded a deeper version (same URL),

Peter Ward · #16 09-07-2013, 06:23 PM

Humm

Rain predicted for the remainder of the week.

Totally revamped the web page. New picture of the Helix, of the rig, some text, even a HST comparison !!

marc4darkskies (Marcus) · #17 09-07-2013, 10:03 PM

Now you're talking Peter - looking verrry nice!

CCDOps though?!!

Rod771 (Rod) · #18 09-07-2013, 10:06 PM

That's an excellent image Peter

If I had seen this yesterday I may have thought twice about posting mine

Well done!

Ta Marcus...but not there yet

YES! CCDops!

Seriously CCDops has the best AG algorithm bar none.

Sure....you can't kill it with a stick and it means very limited automation... but that's what remotely controlled domes, remote-desktops and central heating are for

Ta Rod...but hey, you got to go with what you've got.

I've been *very* impressed by the latest DSLR deep sky images popping up on the net of late.
