Deep field anyone?
Has anyone here done an equivalent to the Hubble deep field?
Or have you thought of trying?

Rolf has put in a half assed 150 hours on the Antlia cluster...
No commitment, I say.

For next year I have planned a 300 hour project BUT it is due to the number of panels more than time on any individual target. So no. I would like to but it would probably be best done with a larger instrument than my 5.1" refractor.

I am hoping to be fully operational by Winter. Dark skies, clear nights and its a given I'll be trying something... Cant wait.

Hubble pointed at a tiny patch of southern sky in repeat visits (made over the past decade) for a total of 50 days, with a total exposure time of 2 million seconds. More than 2,000 images of the same field were taken with Hubble's two premier cameras -; the Advanced Camera for Surveys and the Wide Field Camera 3, which extends Hubble's vision into near-infrared light -; and combined to make the XDF.
"The XDF is the deepest image of the sky ever obtained and reveals the faintest and most distant galaxies ever seen. XDF allows us to explore further back in time than ever before," said Garth Illingworth of the University of California at Santa Cruz, principal investigator of the Hubble Ultra Deep Field 2009 (HUDF09) program.
With my 30 hours invested into the Tarantula Nebula I'm about...5% there...

Could a group get together all do time on the target and all images stacked building an image with unheard of exposure time.
Should be pretty easy other than agreeing what to target.

Yep... bags M42
We need another picture of M42... it's woefully under represented in amateur circles. imho)

What about banding together to tackle some of the propylids in M42?

GREAT IDEA! Once I can contribute, I might run with this... Wouldn't do M42, partly because its done to death and partly obscured from my site, but something deep south... That has some serious possibilities.

I also have obstructed views, but could possibly help with an object deep south.
What about NGC 1763? I'm currently working on this target: http://www.astrobin.com/273012/D/?nc=user

Pretty much my point.... perhaps it is time for us to (collectively) realise that no matter how hard we whack that old piñata... there's probably not more than a stale minty or two left in that old papier mâché carcass.

I am surprised that we did not just get a list of all the tech problems that would prevent such a project but hopefully in the world of digital all will be possible.
Well next step let's make a list and boundaries.
Something Hubble can't see.
An object or a dark place and see how far back we can go, So far South folk in the Northern Hemi won't be able to replicate it.
Objects in either of the clouds maybe.
Time to speculate.
Or an object that North and South can image so it can be a world wide undertaking.

I too have thought about undertaking such a project, and Rolf's Antlia is certainly a benchmark for sure. A galaxy cluster (as per the Hubble deep field images) is (IMHO) a more appropriate target for such a project than a nebula region.

True, but having a galaxy cluster as a target would automatically exclude from the project those of us living too close to the city (heavy light pollution) or with telescopes not suitable for RGB imaging, such as mass produced doublets for example. I tick both boxes
Perhaps a vote or some sort of expression of interest would help to see who would like to really take part in such project?

Being serious for a second here... what about a galactic cirrus survey?
Pretty much anyone with a CCD camera, basic lens, rudimentary skills, equatorial mount and a dark sky could contribute... data reduction I will leave to Ray.
... he's a machine ... T5000 prototype I'm guessing. (and I mean that with the greatest respect)
