You've got to love that filamentous detail :thumbsup:
Well done.

Remarkable detail and clarity for only 2 hours. A winner combination.

Greg.

Noice! :thumbsup::thumbsup::thumbsup: Very intricate filaments in the blue channel. :eyepop:

Holy integration time Batman! :lol:
Now that is a game changer, all that in only two hours?
Amazing :thumbsup:

[Camelopardalis]

Who doesn't love bigger :shrug: :thumbsup:

[Peter Ward]

Thanks one and all...I've since uploaded the (down scaled) full frame, which I prefer to the crop posted earlier. (same URL)

Looks like clear weather again tonight...humm...mosaic or not to mosaic :question:

Lovely image Peter. "Frankencam" looks to be delivering the goods. :thumbsup:

[Stonius]

Beautiful!, Simply gorgeous!

[marc4darkskies]

Very impressive Peter! :thumbsup:

But seriously, 60 mins each for Ha & OIII??!! Your read noise must be tiny. My STXL's read noise is hideous by comparison. I think I need a new camera!

Wow that's sensational

[ChrisV]

That's beautiful. And 2 hrs, quite astonishing!

[Peter Ward]

Thanks gentlemen. In some ways while 2 hours does not sound like a particularly heroic effort, but with the Quad compressor the AP130 comes down to F4.5 which is not too shabby for extended objects.

I bagged another three hours last night, with some colour data for the stars.
.... conditions were remarkably good :) with guiding/seeing induced errors typically 0.18 of a pixel...hence I'm very happy with the data.
Improved results to follow ;)

[Peter Ward]

More data and RGB stars added

Pretty happy with this one now.... :)

This keeps getting better. :thumbsup::thumbsup::thumbsup:
What's your field size and image scale? Might give this a go tonight and see what part is more interesting to frame.

[gregbradley]

Fantastic. A new standard there. AP130 GTX + compressor/QHY600 is the bees knees.

Greg.

[Peter Ward]

Ta Greg. The 3.6 micron pixels are a good match to the AP130 at F4.5
I think my KAF16803 would have also done a great job on the nebulosity but the star sampling would have been too coarse.



Thanks. The camera field is about 3.5 degrees wide. No exactly a small target.

Not exactly bright either !

....the faint stuff is only hinted at in individual sub exposures.
Looking at other examples on the web seems to confirm that this one needs a system with a high S/N ratio from the get-go, to come out well.

Cool - thanks. I might be able to fit a third of it. :thumbsup:
