John.

Yes binning works nicely with this setup. I guess it means the 9 micron pixels are a tad small for my seeing. With 17 megapixels there are tons of pixels for the resolution even binned.

Yes it is working well with that setup. It takes a while to see what
a particular setup is best at and the best way to configure it.

What are you going to do with it?

I like that expression -a belter. I'm going to use that! I guess I should print it up.

Hi Greg,

That is one beautiful photo.....the best I have seen!

Thank you.

Ross.

Thanks very much Ross. I've imaged this object a few times and learn a bit more about each time. I threw out about 5 hours of Ha at 1x1 binning taken about 6 months ago as it was no good. Its taken a bit to understand the scope and what works best with it.

Greg.

He he...naaahhh do some more, do some more!!! you know you want to

Certainly showing some extensions there Greg

and you have done a reasonable job of showing the Ha and some of the OIII structure as well, this is a hard combination to achieve, so not bad - cool.

Looks spectacular

Jen · #26 18-09-2011, 02:59 PM

wow Greg thats just stunning as usual i love your work keep em coming cheers

RobF (Rob) · #27 18-09-2011, 04:00 PM

What a mammoth effort. Certainly show mega extension of the outer halos.
Do you automated the rig at all Greg?

Cheers Mike. You've been quiet on the imaging for a while. Are you planning some new images soon?

Thanks Rob. No not automated but its next to my house. I have an ethernet cable I intend to run to the observatory so I can run everything from inside the house once everything is turned on. But when its all setup it just requires me to roll the roof back, turn everything on, frame the target, program the exposures, focus and start. I then check it from time to time as you never know - the autoguider stopped, clouds came over, who knows!!.

I imagine to get averything automated still requires someone able to physically service the setup from time to time. These setups are quite complex and its amazing how often something needs to be sorted even though it all worked the night before!

Lovely work Greg, although I would have liked to see more RGB in the image. That aside the detail is fantastic.

marc4darkskies (Marcus) · #30 18-09-2011, 08:58 PM

Top shot Greg - very deep and very striking!

Cheers, Marcus

Cheers Marcus. Good to hear from you. Been flat out with the new job?

Another beautiful image Greg. Love the detail in this pic. I really enojoy pictures of old faves which have been improved dramatically with depth and quality that is rarely seen.

Lucas

Paul Haese · #33 18-09-2011, 11:33 PM

Hi Greg, I mean just overall with the RGB. The stars seem a little under saturated to me. The use of the OIII is great for that spoking detail, but it and the Ha dominate the scene. Perhaps maybe blend the RGB over the top of the current image? Something like this I just experiment until I find the balance that seems right. Like I said though the detail is fantastic and that is the main thing really. The RGB is just icing on the cake. My opinion only though.

Thanks very much Lucas. I am glad you enjoyed it.

Lovely Greg. Not much more to add than whats already been said. Very different take on this wonderfull object. Not what I expected to see when I clicked the link. Looks like something from Hubble. Awesome!

multiweb (Marc) · #36 19-09-2011, 11:06 AM

Excellent shot. The Ha is really deep but you did a terrific job in the processing. The Oiii streaks still radiate from the center. Nice blend.. One for the cool wall.

Thanks Marc. I took a few days to process it. I find leaving it and coming back to it you find aspects of it to improve on. Its a good approach to leave an image at least overnight and see if you still like it the next day.

This is an excellent image of the Helix Greg, very deep. For these objects large aperture and long exposures make really a big difference in the final result! Well done

Cheers Marco! Yes I agree, for some objects the CDK17 is ideal. The right tool for the right job.

Well, thats pretty extradinary Greg, the extention is amazing. I was tempted to compare with other classic images of the Helix, and you seem to have gone deeper than all of them. Your processing is a bit brutal though, I think there is some clipping or over compression and it appears to be a tiny bit soft. Thats being picky though, all in all I think its one of the best amature Helix pics Ive seen.
