I did find this...

Quick single shot raw process for starters.
100-400L at 400mm, 60s f/8 ISO800, cropped

Less of the day (night?) - focus shift with temperature is evil!

I'll try a stack on the weekend...

Here's the least-worst process I've done on it now... stack of 14 frames as before. Brings out the noise floor still. I'll have to try longer exposures. Almost did tonight, but by the time I moved the kit out cloud was already appearing overhead so I didn't start.

I still haven't found a nice way to get a decent image out of DSS though. Best I got so far is to export as 16 bit TIF then tweak the crap out of it in PS. There must be a better way?

Yup, that little scrap of land is my back garden. Or what's left of it after a decade of neglect... I might have improved it by now if I can just keep lens lust at bay long enough.

Now I'm really getting jealous.

I haven't been out for weeks and its not looking promising for the next week or so even, just as Orion is clearing our roof as well and coming into range.

A great effort, I'm amazed at how little 'light' you need to capture for this object. I'm itching to try it myself.

Are you getting a decent looking image when tweaking in DSS? If so you need to make sure that when you save out of DSS you are ticking the box that says something like 'apply DSS settings to file'

Hope that helps.

I first pointed at Orion's belt b/c I thought that was where the camera in the wide shot was pointing, but then I moved down a bit. I guess this is the Horsehead nebulae? I don't have an equatorial mount setup so there's some motion blur in this f/5.6, 1 sec exposure at ISO 12800 stacked 5 times aligned & combined with the "multiply" layers in PS.

Haha, no. This is M42 with the running man nebula. For the horsehead nebula you need very long recording times, and it isnt located overthere;)

BTW, which camera do you have? Only 5 frames @ 12800ISO stacked is pretty few :shock:

Thanks Ruben for pointing to the right name!

It is a 5DMII.

Aaah, okay! But still, I think there's some more information you didnt got out with processing. Have a try at the mid- tones!

wait a minute... what?

should I photograph nebulaes and such with longer exposure times?

mine just ends up as star circles

or Im just pointing the wrong way..

I tried using 300mm 2,8 and ISO 12800 but its just too dark...

what am I doing wrong?
