I've actually found something nowhere near Orion :D Amongst the longer subs I found a few 30s ones. This is the Cygnus Loop in Ha and OIII taken with my wide-field NB rig using 1100Ds with 200mm lenses. 30s at ISO 6400. The Ha camera was slightly cooled to 10C and the OIII to 5C. Filters were Astronomik 12nm Ha and OIII clip filters. These are the images as taken, left in colour and stretched in PS then resized to upload here. These DSLR images were loaded into PS in JPEG format so maybe not as good as could be.

Eskimo nebula (its there somewhere) dont know why I tried this object with my set-up but there you go ;)

30s unguided, no comacorrector etc.

Iso 1600 w/300d unmodded, 200p EQ5

Well captured that man.

Thar's what 12" at F4 does for you.

If you can handle the focal length you get decent data very quickly

I started to pick up the outer halo of M57 which usually only shows in Ha shots with just 1 hour of mono-luminance on my 12" f5.

Very nice colour.

In which sense do you mean handle the focal length?

Mine is F5 and I noticed huge coma around all the images, is this part of using F4-5 FL? Any other ways in which the FL is problematic?

Thank u

FL is a problem for tracking. An EQ5 with a 500mm focal length will produce nice images.. I wouldn't want to put 1500mm focal length on it though, which is what I'm using.

Just found a 30s of M42 taken on the 12"F5 with my unmodded Canon 30D and had a quick go a processing it using IRIS.

This is a fantastic thread which surely should be a sticky. The reason? Well, we less experienced are constantly being told not to DARE trying astro imaging without 400 years experience, £5000 to spare, a premium camera and four thousand subs, bias and flats etc etc. What the pics are showing here is that actually you can get quite satisfying and inspiring shots by pointin' and shootin'. Makes me want to reach for my holday snap compact, shove it near the eyepiece and see what happens. Of course I partly jest but this thread is going to prove that you don't need optimum conditions to produce some entertaining shots. PLEASE keep them coming so we can all see what is possible. Thank you!

Great idea for a thread - but I'm going for a slightly different angle as the 'rules' don't specifically state it has to be a DSO..... so here's my single 30sec sub of the ISS flying over my house taken with a standard 18-55mm kit lens at 18mm on a Canon EOS 60D...

Really like that Mike :grin:

I never thought the thread would get much interest, was just a thought I had the other day but am glad people find it useful.

Here's one of my 30 second subs again, this time no processing undertaken or anything. All I have done is saved as .png and reduced the image size (not cropped).

Here is my first effort with an 80mm Apo and LP filter, 30s at iso 800 using a panasonic GH2 m4/3 raw file, no noise reduction applied just masked stretch script in pixinsight

excuses : first effort, got the sensor to flattener hopelessly wrong by adding extra 20mm+ to the separation hence comma at edges and poor alignment

Much better than my first effort on M42 that's for sure! Yes, a good first go - quite a lot of detail in there :)
