So who's up for the challenge?

[Starman]

On this month's Sky at Night (BBC 4, Sunday 12th of April at 10pm) I'm setting you a challenge to image the Hubble Deep Field (the original one in Ursa Major). You're  a talented lot - let's see what you can do...

Hoping for some clear skies to have another go at M63 so may give this a shot while I'm thereabouts, don't hold your breath though

Hi pete,

I think Robbie Ince managed this a few years back from kielder and got down to mag 22.8 !

He called it the "kielder deep field"

A great challenge though !

[nicks90]

just read that KDF post, most impressive! It would be amazing dedication if he was able to resolve all the faint fuzzies across the entire image, as opposed to that one small square - but i would imagine that would take years!

however, the above S@N challenge has to be tweaking the interest of those with longer FL scopes - maybe a good one for those with SCTs and ditch the focal reducer and see what happens?

Hmm I'm a mere planetary imager so shall bow out to the DSO dark side guys on this one Looking forward to seeing people's results though.

Yes, I'd seen the KDF - a fantastic result, done in a field! I hope others do have a go though - I'd love to see what you can achieve.

Peter,

you book the clear skies and I'll have a good go at the 'deep field' with my limited equipment.

don't know why that posted twice?

I've added a chart of the HDF region to this thread:

With no hope of being able to really image the Field, I thought it would be fun just to try to locate it. I used a few iterations of AstroTortilla to get within a gnat's whisker of the location, then just a few token subs. I Photoshopped a box to scale, and oriented it by aligning an image from Wikipedia. Hope I got the Moon scale circle right!  :-)

Best effort so far?   (8"/F/4 Newt + 20min Watec 120N+ Video Cam)

At the moment, nothing in the actual HDF itself (short exposure time!)

But possibility of brighter objects in the vicinity matching with others?

Almost tempted to give it a rather longer "burn" - Weather permitting!

[paulobao]

I'm in!

Tonight I will try 9x 1200s! Unfortunatelly I cannot change my resolution in remote (it will be just 2.19arcsec/pixel). I will post the result (!) tomorrow morning  .

Using the location for the HDF from this image I think there may be 6 or 7 possible objects in my attempt?

Hubble Deep Field area- enhance crop of 180s single sub, Lodestar 2X camera, 12" F4 Newtonian (unguided).

Original sub & position of crop

EDIT- more info on the other thread

My efforts on this.  More discussion on the Video astronomy forum.

Hi,

Here my effort from the past night!

I am not convinced that this is the real HDF...! I think there is some offset from the original one!

I will try to draw the lines more accurately and I will try to annotate some the objects (?)

Observatory: MPC J15 (PT)

Tak FS102 NSV @ 641mm (res:2.19 arcsec/pixel)

QSI532WS-M1 @ -20ºC

Unfiltered: 9x1200s

Cheers,

paulo

[laser_jock99]

Taking a lead from Tims post, I plotted the outline of the HDF on my image and posted the HDF alongside. With the four main galaxies highlighted it becomes easier to pick out maybe half a dozen of the real faint ones from the noise.

Not bad for just a 3 minute unguided sub!

Some great images here. I was wondering what magnitudes these objects are? .....and with so many people having a go is it possible to stack everyones images into one image ?

Im purely a visual observer so apologies if these are daft questions .

Cheers

[paulobao]

Hi,

After a lot of work I think this is a more realistic approach to the HDF!

The red circles are the objects I THINK could be identified in my image! 

Next step it is to annotate the objects (and of course....get more exposure time!)

Cheers,

paulo

[Starman]

Whoa - some great results here! I hope you're enjoying the challenge. I've never done the HDF before and have started to get a bit fixated on it, letting the planets go by the wayside as a result! I've got a 3 hour result which I've annotated with magnitudes (thanks Robert Ince!) and am happy to claim a depth of +22.3 from my home in Selsey. The result isn't very clean (or pretty) yet as some annoying hot pixels have made it through the calibration process and have been revealed by the extreme stretching. I'll deal with these later. But if it helps, here's the evaluation result with the magnutudes marked...

[paulobao]

Nice :-)

I used your annotations to update my image (Hope you don't mind  ) .

I used astrometrica but obtained different values for the mag!

Thanks,

paulo

[MikeD]

Here's my go, shot with 10" f4.8 newt at prime through a CLS LP fllter.

59 @ 600 seconds

Shame about the dust bunny that for some reason even though it looked sorted on the individual subs after calibration, came back through after stacking.

the giff flash (after 2 seconds) is a scaled version of the Hubble deep field image.

lots of galaxies in the full field of view.

I could have probably got away with longer subs but its been a bit windy here so I decided not to risk loss of subs through wind.

Click images for full size.

Mike.

Count me on board with this.  i'm going for it with either my C9.25 or RC8 when the obs is up and running.

I imagine this will be a long running thread!

[laser_jock99]

@Pete- thanks for posting up the galaxy magnitudes. Now I'm even more chuffed- the camera I normaly only use for guiding can reach down to magnitude 20 in three minutes. I tried longer subs but being unguided they were poor. I tried stacking the good 60/120/180s subs- but still showed no more than the single 180s. Will give this another go when conditions allow.
