The 30 Minute Challenge

[Kirscovitch]

Here's my weak attempt at C4. I originally took 10 subs at 190 seconds but stacked 9 to keep it under the 30 minute mark.

9x190 800iso unguided. 5 darks. No flats or bias

Unmodded Canon 1100D

Captured with BYEOS. Stacked in DSS and "played" with in Gimp

I say "played" because I have no clue what I am doing yet lol.

I'm almost too embarrassed to post this .. Great images from everybody else. Really inspiring. I don't have a telescope I can image through yet but I've just bought a canon 1100d so here's my first stab at DSO . Here's Vega and the double double. A stack of 50 1.6 second exposures at iso 800

Paul,

I think your image is suffering badly from jpeg data compression- there's only 4Kb worth of data left! If you look at the properties of some of the other similar sized images posted in this thread some are well into the 100's of Kb.

Can I suggest you re-post the image without so much compression? Hopefully there will be more detail then.

Apologies .. I posted using a mobile app.

[Paul1969]

And i'm obviously still having difficulties  .. :-/

That would certainly not help the image quality. Even my photo hosting site seems to apply it's own 'compression'. It's annoying after you have spent many hours working on a single image to have it robbed of detail!

Imaging time has been rare here due to so much cloud.

Seeing Vega and the Double Double mentioned above, I already had done the Double Double in short breaks in the cloud.

Here is a 1sec image at ISO 6400.....EP projection with a Baader Hyperion Zoom set to 8mm, other kit as in my sig.

Nice image you have realy got the bug and are producing great results.

[Kirscovitch]

Thanks Alan. Hardest part for me at the moment is getting my post processing down. I just keep playing with things until I get something halfway decent lol.

Going for the shortest exposure DSO record with this one - M81 in just 4 seconds

Using the new Starlight Xpress Lodestar x2 in 2x2 binned mode and 10" F2.9 Newtonian scope.

[glowingturnip]

a quick reprocess of some old data, just 4 out of 12 light frames since the rest were irretrievably streaked, 4x180s iso400, equipment as per sig, DSLR through 2x barlow 

i don't remember there being this many stars last time I looked at it...

Most of my images have been less than 30 minutes worth of integration, though I try for longer these days (but the clouds don't play ball of course)...

Here's one for the sub one minute category.

A single 54 second sub of M8 in Sagittarius- made by stacking various stretches of the one sub.

greetings

My effort of crescent nebula 10 90 second iso 1600 canon 5Dmk2 just lights ruined in DSS because I don't know what I'm doing yet.

last week.

Ok heres one from me - its a single 10 minute sub of the Wizard Nebula (NGC 7830) in Ha.  Taken last night when waiting for the clouds to clear.  Pesky forecast - they never did clear and things got worse and worse so I packed in.  I was getting very good readings from the focusing so its a real shame.

Anyway Here it  is

Glad to see they are still coming...

Keep it up Guys....

Hope to get back to it myself soon been real busy moving house...
